Improving Treatments

Filling a survey every day takes only a minute, but it yields important information for understanding the pandemic.

One small step for you, one giant leap for all of us.

If you are healthy, you just push one button every day. If you are sick, you answer a short questionaire every day. It won’t take more than a minute. Sometimes you can help with new studies, e.g. by recording the sound of your breath.


Every datapoint helps science

You think your data is not that important? Only if many people participate, important treatment and decision strategies can be derived from the data. Every single donation of data counts.



The data provide insights into the spread and course of disease of COVID-19 in unprecedented detail.



Identifying early indicators of severe disease progression is important to protect as many people as possible.



Medical studies use the app to collect data and recruit probands to improve treatments.

You stay anonymous

We collect only the most necessary data - and nothing else. No motion profiles, no names, no phone numbers, no email addresses, no device information. We only store a random pseudonym and your answers to our questions, and they are about your health, not your identity. You can delete your data at any time. More in our privacy statement.

About this project

This project was initiated by scientists from the Tübingen AI Centre at the University of Tübingen and the Max Planck Institute for Intelligent Systems as well as medical scientists from the University Hospital Tübingen.

With this project we want to collect urgently needed data on COVID-19 as quickly and efficiently as possible and support medical and scientific studies in this field. Here, the app serves as a platform to answer as many questions as possible. To this end, continuously collected health data of as many people as possible are invaluable.

The platform as well as the collected data will be made available to trustworthy partner institutions for scientific and medical purposes regarding COVID-19.

Let us stand together against COVID-19
