M-sense - App against Migraine
End-to-end design of a medical app that helps patients to reduce migraine attacks
About the Project
M-sense is a medically certified digital therapeutic (DiGA, prescribable in Germany) for people who live with migraine. The hard part of a product like this isn't the feature list — it's earning enough daily trust that people actually open it on a bad day, not just a curious one. A migraine app only works if the relationship between user and product survives the disease itself.
The discovery question across six years of design was: what makes someone open this when their head already hurts? Every feature decision — tracking, exercises, the "Brainy" assistant, cycle-aware insights — had to clear that bar.
Project Execution
I led end-to-end product design from early concept through medical certification — driving discovery research, UX, brand, and design specification across iOS, Android, and web. Regular user testing, in person and remote, kept the team close to the bad-day reality.
The product reached 60,000 monthly active users and became a regulated digital therapeutic that doctors can prescribe. The headline outcome was certification and community. The quieter one was a six-year design system and decision history that let a small team ship and maintain a regulated medical product.
