5Product description

The Mika app aims to reduce symptoms related to psychological distress following a cancer diagnosis and associated treatment and with that to increase the quality of life.

To this end, Mika includes an evidence-based psychological distress test based on a clinically validated screening instrument. The test leads patients through guideline-compliant psycho-oncological interventions that consist of psychological education, relaxation techniques, strength and flexibility exercises as well as exercises to strengthen your coping skills with methods taken from cognitive behavioural therapy (CBT), acceptance commitment therapy (ACT) and creative therapy.

These resource-activating exercises seek to improve health-related behaviour, the way you manage psychological distress and how you deal with your condition. A personalised knowledge base offers further psychosocial and psycho-oncological support with compact information on individual types of cancer, guidelines and supportive health-related behaviour.

5.1App functions

Check-up: this guideline-compliant screening instrument lets patients measure their psychological distress levels on a weekly basis and make a note of areas causing psychological distress. Patients can make a daily record of any side effects of their treatment in a symptom diary with a graphical display of their development. Data can be exported and shared with your medical team for discussion, also with a possible view to adjusting medication-based treatment.

Journeys serve the purpose of training your psycho-oncological coping skills. This modular function contains practical exercises designed to reduce psychological distress.  

Discover provides guideline-compliant and evidence-based information that is suitable for a lay audience on individual cancer diagnoses, current treatment options, nutritional knowledge, recipes, tips on dealing with physical restrictions as well as individual relaxation and physical exercises.

Involvement of medical institutes and organisations in the development of the app

  • Leipzig University Cancer Center (UCCL)
  • Leibniz Institute for Resilience Research
  • Charité – Universitätsmedizin Berlin


Mika is intended for patients who have been diagnosed with a malignant tumour (cancer) and covers all kinds of malignancy.

6Contra-indications and warnings

  General information

  1. Mika cannot replace a doctor or a therapist.
  2. Mika cannot provide a diagnosis. This can only be supplied by the medical team in charge of your treatment.

  4. Please only use Mika if no reasons not to use the app (i.e. counter-indications) exist or your medical team has assured you that you can safely use the app in your particular case.
  5. The recommendations and instructions of your medical team always take precedence over any suggestions provided by Mika. You are urged to follow them – or risk damaging yourself and your health.
  6. Please answer any questions asked by Mika carefully and truthfully, particularly with regard to your symptoms, medical indications such as diagnoses and treatment, physical limitations and capabilities as well as pain and any other symptoms. Entering wrong or incorrect information into Mika can result in the app offering you information and exercises that are not appropriate for your situation and current capabilities. Attempting exercises that are not appropriate for you can result in injury or other damage.  
  7. Before attempting any Mika exercises, please closely observe the written information flanking any audio and video instructions and then follow the instructions provided in the video or by the audio. These additional text-based details contain important information on counter-indications and exercise instructions. If you feel unsure about how to do an exercise, take a break from it and consult your medical team. Although these exercises are designed to be performed by you on your own, doing an exercise incorrectly can result in injury or emotional distress.

The Mika app provides various physical exercises and techniques taken from the field of psychotherapy. The positive effects of these exercises, especially the physical exercises as well as relaxation, mindfulness and acceptance techniques, have been proven in clinical studies. Even so, these exercises should not be attempted if certain risks exist. Please therefore always observe the following information to ensure you use Mika safely without causing yourself any harm.

Contra-indications and medical information on physical exercises

Before you begin doing any physical exercises, please always check with your medical team whether you should be doing physical exercise at all and if so which restrictions apply. The following limitations apply in general. They cannot replace first consulting your doctor. 

Following surgery, the surgical wound must have healed before any physical exercises can be attempted.

If an implant has been fitted, your medical team must confirm that it is possible for you to lie face down again.

In the case of bone metastases: if bone metastases put you at risk of breakage, certain exercises (depending on the location of any bone metastases) can be subject to restrictions that your medical team will have to discuss with you on an individual basis.

In the case of orthopaedic restrictions: if certain exercises are not possible or only in restricted form, please refrain from attempting them.

Physical exercise should be avoided if:

  • you are in severe pain and if exercise makes the pain worse,
  • you are running a fever or temperature of more than 38 °C,
  • you have an acute infection,
  • you are suffering with nausea or vomiting,
  • your cognitive functions are impaired or you are confused,
  • you are feeling dizzy or have problems with your cardiovascular system,
  • you are currently experiencing acute bleeding or are more prone to bleeding: low platelet count (thrombocyte values of less than 10,000/µl),
  • you are prone to or displaying signs of bleeding: thrombocyte values from 10,000 to 20,000/µl,
  • your haemoglobin values are below 8 g/dl of blood.

Note: these contraindications do not prohibit all activity. Strenuous exercise should, however, be avoided. You can still go about your daily activities as usual.

Counter-indications and medical information on mindfulness, acceptance and relaxation exercises

Please do not attempt these exercises – or only if your medical team has confirmed that they are safe for you to attempt – if:

  • you are currently experiencing severe psychological distress and you are not receiving professional psychotherapeutic support,
  • you suffer with severe depression, psychoses or other severe mental health problems that could be made worse by relaxation and mindfulness techniques,
  • you are in severe physical pain.

If any of the points mentioned above apply to you, please consult your doctor before attempting these exercises.

Even if none of the above points applies to you, it can happen that not every exercise offered by Mika is helpful at any given time in the course of your condition. Therefore, if you feel an exercise is causing you psychological distress or is not doing you good physically and/or emotionally, then please take a break from it. You can try again at a later point in time. If it still fails to do you any good or continues to cause you severe psychological distress, then please stop doing it altogether and do not attempt it again. If these feelings of psychological distress persist, please consult your medical team if necessary and inform us about the problem by sending an email to

Exercise sessions cannot replace psychotherapy or psychiatric treatment. If your mood continues to be low over a longer period of time or if you are suffering with extreme panic attacks, are harming yourself, are thinking of taking your own life or have any other mental health symptoms, please consult your GP, medical specialist or a psychotherapist.

Help in acute crisis situations can be provided, for instance, by the Samaritans on 116 123 ( ).

If you are seriously considering or are intending to take your own life, please call 999 as a matter of urgency.

6.1Cybersecurity related recommendations

  • It is important to secure the device (E.g, password or a biometric login) on which Mika is installed since you would be storing health related information.
  • It is recommended that you update Mika whenever a latest version is made available to adopt the latest security fixes.

7Side effects

Using Mika is not associated with any known side effects.

8Duration and frequency of use

Use the ‘Check-up’ regularly to assess how much psychological distress you currently feel. 

If you are receiving treatment for your condition or are suffering with any long-term effects of your treatment, you are urged to regularly record any symptoms that arise and their severity. If necessary, this record of your symptoms can be used to adjust your medications in consultation with your medical team and so reduce any side effects.

To get the best out of the ‘Journeys’ therapy programme, you are recommended to complete the suggested exercises on a regular basis.

9.4Using the Mika app

Mika is a digital medical device that complies with the German law on medical devices. To make full use of Mika, you will need:

  • a partner code (optional)
  • a Mika user account.

9.4.1Information on the partner code

You may have received a partner code from your hospital, your doctor or a self-help group, which you can enter during initial installation of the app. Any additional or new codes can also be entered at any later time in the app’s settings. This code is also referred to as a license key, activation code or registration code.

If you do not have a partner code, you can skip this step and continue without one. You will still be able to make full use of the Mika app even without a partner code. 

9.4.2Information on your user account

To make sure that only you will be able to access your data, which will be securely stored in a GDPR-compliant manner, and to let us contact you, you will have to set up a user account. All you need is a valid email address and a secure password. Setting up your account is entirely free of charge for you.

Your securely encrypted personal data will be stored on servers located in Germany. We will never sell your data, but will instead use it only to optimise Mika for you.  

9.5Start and initial set-up (onboarding)

When you start Mika for the first time, you will be taken through a basic initial set-up (called onboarding).

You will first be asked to enter a partner code. If you have a valid code, your account will then be set up. But you will still be able to use Mika even if you don’t have a partner code. Further information on the license key (or code) and your user account can be found in the ‘Using Mika’ section.

Once these formalities have been completed, you will be asked questions regarding your current status: your age, your gender, your diagnosis, whether you are currently receiving treatment, etc.. These details will be treated in the strictest of confidence and securely encrypted for storage. They serve the purpose of optimising Mika to suit your requirements. Any questions you would rather not answer can be skipped.

The individual steps you will encounter during your Mika onboarding are explained below.

9.5.1Logging in or new to Mika?

Figure 9 Detailed Problems


In the course of setting Mika up for the first time, you can also conduct a first partial check-up, during which Mika will ask you about your current health status and/or how psychologically distressed you feel. You can find detailed information on how exactly this check-up works in the ‘Check-up section.

9.6Mika’s basic structure and functions

Once you have completed the initial set-up, you will have all-area access to Mika.

Mika consists of four main areas that you can access at any time from the tab bar at the bottom of the screen. The following screenshots may differ from the display on your device depending on the Mika version and the operating system of your device.

My Mika is your personal start page. This is where you will find personalised messages, information and notes on using the app.

From here, you will also be able to access Mika's settings (tap on the cogwheel symbol on the start page).

Check-up is the area in which you can record your symptoms and keep track of the way you feel in general. This will give you a better overview of the course your condition is taking. In addition, you can pair Mika with your fitness tracker and/or your smartwatch.

Journeys offer you an extensive programme of exercises that are designed to help you deal with the emotional and psychological effects of your condition.

Discover provides you with information, physical exercises and practical tips that aim to help you live with your condition day to day. Content that is particularly relevant to you is highlighted automatically by Mika. In addition, the ‘Discover’ section lets you search for keywords or set bookmarks at any time.

9.7My Mika


‘My Mika’ is the central area from which you can access all Mika functions. The actual composition of ‘My Mika’ will gradually change over time as the app learns to better adapt to the way you use it and your interests.

‘My Mika’ is divided into sections that will gradually change and/or be added to over time. At its most basic, which means when you first start using the app, Mika will display three sections:

The What can you do? box provides tips on which things you can do in your current situation. In the course of time, the composition of these tips will change depending on how you use Mika.

Recommended for you highlights content that Mika believes would be particularly relevant for you. In this regard, Mika may highlight new functions or content such as journeys, videos, texts or exercises.

Lastly, Suggested for you lists articles from the Discover section that were selected by Mika based on information provided by you. The composition of this section will change over time in the same way as the previously mentioned sections. Whenever you see anything that takes your interest, simply tap on it. Tapping on the cogwheel symbol at the top right will take you to Mika’s settings.




The Check-up delivers an overview of how you feel and your symptoms. Regular and active observation of how you feel and your symptoms will help you to better understand the consequences of your condition. In addition, this data can provide your medical team with valuable information regarding your treatment.

How you feel seeks to find out what you would say if asked ‘How are you feeling?’. In Mika, you can indicate how psychologically distressed you currently feel on a sliding scale. If you are feeling really good, you will feel only a low level of psychological distress or even none at all. The slider would then be set to a lower value on the scale. If you are not feeling so good, you will be experiencing psychological distress – and the slider will rise on the scale. If you regularly record the way you feel, you will get a good idea of when and why you feel better or worse.

Symptoms can be of a physical, emotional or mental nature. In contrast to the way you feel, it is often necessary to specify and record symptoms in much more concrete terms. Such symptoms will mostly be a direct consequence of your condition and treatment. Depending on the symptom, Mika uses various scales that are designed to help you to evaluate the severity of any given symptom. Please note: not every person experiences the same symptoms. Select those symptoms from the list that you are actually experiencing. If a symptom is not listed, you can add it yourself.

Depending on the app version, the start page of the ‘Check-up’ section may offer further options: 

‘Creating a new diary entry’ (currently only on iOS devices). Tapping on this button will take you to the Mika diary, in which you can make a note of your thoughts and come back to them again at any time. Further details can be found in the ‘Creating a diary entry' section.

‘Pairing fitness trackers, smartwatches and health apps with Mika’. Choosing this options lets you, for instance, export data from your fitness tracker for integration into the Mika app. Further details can be found in the ‘Pairing other devices and services with Mika’ section.

Under ‘Exporting already recorded data’ you can do just that. You can have all your previously captured data exported as a PDF or in machine-readable format for storage outside of Mika or you can share it, for instance, with your medical team.

9.8.1Overview of how you feel

The overview of how you feel shows how the way you feel has developed over time. You can change the period of time for which data is displayed by using the segment switch to choose between 7 days, 30 days and 12 months. This lets you choose the time period you want to review yourself. When you first start using Mika, this overview page is likely to look rather empty. But making regular use of the Mika ‘Check-up’ will soon show you how the way you feel develops over time.

By the way, you can also export data previously captured by you as a PDF or in machine-readable format (in accordance with the FHIR standard). Simply go to the start page of the ‘Check-up’ section or go to Mika’s settings and then to the ‘Export data’ subsection. 

9.8.2Recording the way you feel



The way you feel is measured in the same way you would use a thermometer. Move the slider within the scale with your finger. The higher up the slider is on the scale, the more psychological distress you feel.

Choose a value that corresponds to the severity of your psychological distress level, in which 0 represents no psychological distress at all and 10 an extreme, maximum level of psychological distress. After you have set the value, tap on ‘Next’.

In the following step, you can then specify the area(s) of life that you feel are causing you psychological distress.

Choose an area of life that is contributing to the way you currently feel. Tap on the respective area to be shown various aspects that you can additionally supplement if required. Tap on ‘Done’ at the top right to confirm your selection.

If you like, you can also add several areas of life and aspects. Please remember, though, that it makes sense only to select entries that correspond to actual contributing factors regarding anything you are currently dealing with.

Recording the way you feel and/or your current psychological distress levels serves to better understand which topics are especially important to you right now; it is less about extreme accuracy, rather it aims to ‘take your temperature’. The idea behind it is to gradually make you more aware of when, for instance, physical and when practical problems are at the forefront. In this way, you will gain a better understanding of why you feel the way you currently do.

Please note: if clearly physical aspects are currently at the forefront, you should accurately record your symptoms. If you enter physical symptoms while recording the way you feel, these will also be added to your symptom list.

9.8.3Symptom overview

The symptom overview displays how your symptoms have developed over time. You can change the period of time for which data is displayed by using the segment switch to choose between 7 days, 30 days and 12 months. This lets you set the time period you want to review yourself.

To see the course of individual symptoms over time, simply tap on the blue symptom. If you recorded several symptoms, you will now be shown a list of all recorded symptoms.

Tap on ‘Record a new value’ if you wish to record existing or new symptoms.

By the way, you can also export data previously captured by you as a PDF or in machine-readable format (in accordance with the FHIR standard). Simply go to the start page of the ‘Check-up’ section or go to Mika’s settings and then to the ‘Export data’ subsection. 

9.8.4Recording symptoms

It is recommended that you regularly record the severity of any symptoms you want the app to monitor over time. Mika lets you do this with ease.

Depending on the kind of symptom, you will be shown various scales, the principle of which always remains the same. Simply select the value that applies to you or the applicable description by tapping on it. Once you have updated all the symptoms you want to monitor in this way, tap on ‘Apply values’.

To add a new symptom to your list of monitored symptoms or to delete a symptom from the list, tap on ‘Add or delete a symptom’.

9.8.5Recording new symptoms



You can add new symptoms at any time in one of the following ways:

  1. Select one or more symptoms from a standard symptom list.
  2. Search for a specific symptom by entering it in the text input field.
  3. Use the text input field to add a symptom that is not on the list.

To search for a symptom, simply tap on the text input field and start typing. After you have entered a few letters, you will often be shown a corresponding symptom. Tap on it and it will be added to your list. If the symptom has not yet been included in Mika, you can add it yourself. To do so, tap on ‘Add new symptom’.

Please note: you are recommended to focus only on symptoms that you are currently actually experiencing. The course any health condition and its treatment takes will differ in every individual case and just because a symptom has been included on the standard list of symptoms does not automatically mean it has to apply to you.

9.8.6Creating a diary entry (only iOS)




You can keep your own personal diary using Mika and simply make a note of things that are currently on your mind. You can also use the diary to make a record of additional information regarding the way you feel or about any treatment-related side effects. As a result, you will even be able to track the effects of any new medication, for instance, days later.

To create a new diary entry, simply tap on the ‘Creating a new diary entry’ tile on the start page of the ‘Check-up’ section. The overview page of your diary will then be displayed and you will see a list of all former entries made by you. A new entry can be made by tapping on the blue ‘Create new entry’ button. This will automatically create a new entry for the day in question and you can start typing straight away. Once you have finished, tap on ‘Done’ at the top right. The new entry will then appear in the overview. If you want to edit and/or change an entry, simply tap on the corresponding entry. You can then edit or even delete the entry if you want. All diary entries can also be accessed via the calendar. This is a quick way to check what was on your mind a few weeks ago. 

9.8.7Calendar (only iOS)

Mika includes a calendar that you can view in the ‘Check-up’ section by tapping on ‘Calendar’ at the top right.

The Mika calendar provides an accurate daily overview of your previously recorded data. Ticks placed in the overview indicate that data is available for these days. An overall overview is created for each day that displays all captured data at a glance:

  • The way you felt and if applicable any aspects that contributed to the way you felt on this particular day.
  • Symptoms observed by you.
  • Any data captured by your smartwatch. 
  • The diary entry made on this day. 

You can still edit some of the data at a later point in time by tapping on the pen symbol to the right of the section name.

9.8.8Pairing other devices and services with Mika

You can pair Mika with your fitness tracker, your smartwatch and with other health apps. To this end, you will have to allow the respective service to share data specified by you with Mika. This enables any values you recorded in Mika, e.g. symptom details, to be combined with data automatically recorded by your device. Please be aware that this process takes place in only one direction – values that you have recorded using the Mika app will never be transferred to other devices or services.

Sharing data with Mika is particularly useful if such data says something about your activity levels, for instance the number of steps taken per day or the average amount of sleep you get. Such values let Mika get to know you even better and enable the app to offer you specific content to match.

This is how it works:

  1. Tap on the ‘Pair fitness trackers, smartwatches and health apps with Mika’ tile on the start page of the ‘Check-up’ section.
  2. Select the manufacturer of your device from the overview shown and/or the service that you want to pair. If the manufacturer of your device is not included on the list, it is not yet possible to pair Mika with it. Please check back at a later point in time since new manufacturers are constantly being added to the list.
  3. In the next step, you will be asked to log into your account with the manufacturer of your device (for instance your Garmin user account).
  4. Now you can select data you want to share with Mika. Please note the following in this regard: when you have newly paired a device and/or service with Mika, you are likely not to see all the captured data to begin with since Mika continually ‘learns’ and will initially capture only simple values such as the number of steps you walk per day or the amount of time you spend asleep. Mika will gradually collate and add to this data.
  5. Once you have confirmed your selection, your device and/or service will be paired.

Due to the synchronisation process, you may have to wait a few minutes before the overview displays your data.

The following fitness trackers, smartwatches and health apps can be paired with Mika:

  • Apple Health (only iOS)
  • Fitbit
  • Garmin
  • Polar
  • Withings      Viewing paired data

You can view data from paired devices in a new overview. For every category actively evaluated by Mika you will see a tile displaying the latest updated value in each case. Tapping on a tile included in the overview will display the details and you can track the way they developed during various time periods..      Disconnecting paired devices and services

You can disconnect any pairings between your devices and Mika at any time. Simply go to the Mika settings, then to ‘Manage paired devices and apps’ under ‘Paired services’ and select which device/service you want to disconnect from Mika.

All previously captured data will be retained by Mika. You can view such data at any time via the ‘Historical data’ overview, which you can access from the ‘Check-up’ start page. Your data will be stored by Mika until you delete your user account. You can also export your captured data at any time for use in other applications.      Information on data protection

To make sure that Mika can capture and interpret your data from another device, this data must first be translated into a format that Mika can understand. This happens automatically using a service called Thryve, with which we collaborate. This service works like a bridge between your fitness tracker and Mika. Since both have to communicate with one another, the following applies: the manufacturer of your device will gain knowledge that you use Mika. And Mika will know which device you use. However, the device manufacturer will never have access to your Mika data (symptoms, how you feel, progress made, etc.). What you do in Mika stays in Mika.


Mika’s journeys are designed to help you to better deal with the emotional and physical consequences of your condition. These journeys were developed on the basis of scientific evidence and in close cooperation with experts.

The list of journeys shows you which topics are currently available. This list is added to on a continual basis and can also contain specific, treatment-related journeys that may not be relevant or visible for every user.

Every journey addresses a main topic. You only have to select the ones that interest you to embark on a fascinating and educational path. Simply tap on the respective tile.

Grouped into individual stages, journeys consist of various exercises and provide food for thought. As these stages build on each other, it is recommended to work through any given journey from beginning to end in the order suggested to ensure you get the most out of it.

9.9.1Basic structure of a journey

Every journey follows a clear structure that is designed to help you make sense even of more complex topics at your own pace:

Each journey is made up of individual stages that include certain exercises and together form a meaningful whole. Think of a stage as a chapter in a book. You will automatically progress from one stage to another.

Every stage begins with a short introduction to the respective topic that will tell you what it is about and what to expect.

After that, you will be asked for a self-evaluation that is intended to help you to establish where you are at present and what a good, achievable goal might be for you.

This is followed by various exercises that will help you to explore the respective topic. These include:

Please read the ‘Counter-indications and exclusions’ section before using this section of the app.

  • Mindfulness exercises that aim to put your focus on being more aware of your body and your mind. These exercises are audio files and you will find them in various journeys as recurring exercises for completion every day.
  • Physical exercises in the form of videos that are designed to strengthen your body. You can choose the degree of difficulty of these exercises.
  • Relaxation exercises that are designed to help you find inner peace. These are longer audio files that, for instance, can help you fall asleep.
  • Journal exercises that let you specifically reflect on challenges and order chaotic thoughts. These guided writing exercises are designed to be completed on your own on a daily basis.
  • Explanatory or informative content that provides valuable background knowledge such as videos, diagrams or texts that let you learn something about yourself, your condition and/or its effects.

In addition, many journeys contain courses to be completed over several days that include exercises which you will ideally do on a daily basis. These can be mindfulness exercises, but can equally be physical exercises. Regardless of how long you may want to spend on the content of a journey, you will benefit greatly from actually doing the exercises on a regular basis. This will allow them to become a valuable part of your daily life and you will reap their full benefit.

To begin with, you can of course try various journeys until you find one you want to complete from start to finish. And: you can take a break from a journey at any time and come back to it again later.
