Developed in cooperation

The symptom tracker was developed in cooperation with Charité – Universitätsmedizin Berlin to supplement CovApp, the online questionnaire that helped people with potential symptoms of COVID-19 decide the appropriate measures to take.

Your symptom history when you need it

A day-by-day breakdown of your symptoms can help you take better care of yourself and be prepared for a possible visit to the doctor. Your personal symptom report in the symptom tracker is always accessible in the Data4Life app and will continue to be available for future reference.

Update your symptoms regularly

It’s important to record your symptoms as often as possible and incorporate it in your daily routine. Self-reporting is an effective way to document your health. The more often you use the symptom tracker, the more helpful and accurate your personal symptom report will be when you need it.

Show your doctor

Documenting your symptoms can be for more than just personal reference. If you decide to visit a doctor or hospital at some point during the COVID-19 pandemic, you can show your complete symptom history to a trusted medical professional and provide all of your information.

German opinion: Donate data to fight COVID-19

The COVID-19 pandemic has truly reminded us how much our health and quality of life depends on medical research. Understanding a threat like coronavirus disease is essential to improving treatment and evaluating preventive measures like a vaccine.

In a survey from April 20–April 30 2020, Data4Life asked 5,002 people in Germany if they would donate personal health data to help research coronavirus disease. An analysis of the results offers new insights on how public opinion varies throughout Germany among people from different regions and backgrounds.

Is the symptom tracker a medical device?

A digital solution for documenting symptoms is not a medical device.

From a legal perspective, the symptom tracker is not classified as a medical device.

Data4Life sought advice on this matter from D+B Rechtsanwälte, a law firm specializing in healthcare law. As Dr. Ulrich Grau, a partner at the firm, explains: “The classification of a product as a medical device depends to a large extent on whether the manufacturer intends for the product to be used for one or more specific medical purposes. In the case of health apps, the following medical purposes are particularly relevant: diagnosis, prevention, monitoring, treatment, and alleviation of disease.”

Exclusively documentation and data storage.

The symptom tracker is not intended for medical purposes. The product was not developed to help diagnose, monitor, or treat diseases. On the contrary, the sole purpose of entering day-to-day health information, according to Data4Life, is to document and store this information. Data4Life also expressly refers to this in the presentation and promotion of the symptom tracker.

As Dr. Ulrich Grau points out: “Digital solutions that the manufacturer intends to be used purely for documenting and storing data – as is the case with the symptom tracker developed by Data4Life – are not medical devices, since documentation and data storage are not medical purposes.”

Symptoms are not analyzed, evaluated, or monitored.

Besides the fact that it is not intended for medical purposes, the symptom tracker is also not classified as a medical device because the data entered by the user is not influenced in any way. The symptom tracker doesn’t analyze, evaluate, or monitor symptoms entered by the user. It simply documents and stores the data.

The symptom tracker is the modern digital alternative to a conventional health diary.
