Registration for the study
Here you will find all the important information about our app and how to take part in our free study, which has been running since spring 2025.

Hi, I'm Hanna, co-founder of coreway. As a sufferer of inflammatory bowel disease, I know how challenging it can be to stay in control of the disease. Our 2024 pilot study has already shown that relapses can be detected early by analyzing vital parameters and health factors. Also Hirten et al. has investigated the early detection of chronic inflammatory bowel disease using vital parameters and confirmed its feasibility. Our app has also been certified as a risk class I medical device since spring 2025. The current three-month study serves to certify the app as a medical device in risk class IIa, with the aim of being able to display the risk of relapses in the app in the future.
- Diagnosis of a chronic inflammatory bowel disease such as Crohn's disease or ulcerative colitis.
- Minimum age: 18 years.
- Regardless of whether you are currently experiencing a relapse, a chronic relapse or are in remission - all disease states are welcome and valuable for the study.
- You can also specify other illnesses when registering. They are not an exclusion criterion.
- The motivation to support CED research through daily commitment.
- Participation in the study is 100 % free of charge and without obligation.

As an internist in private practice for many years, I consider the application to be a useful tool for people with IBD. It supports patients and enables further treatment at home.
