Can a smartphone app cure your sleepless nights?
NCT ID NCT04949360
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a smartphone app called SleepUp can help people with insomnia. The app provides cognitive-behavioral therapy (CBTi) and extra features like meditation and relaxation sounds. Researchers will compare the app to standard therapy with a psychologist and to basic sleep hygiene education. The goal is to see if the digital approach improves sleep and is easy for people to stick with.
