This study was closed on April 23, 2020, and we will no longer be collecting or reviewing data from the SleepHealth App after that date. No new participants will be enrolled and the SleepHealth app is no longer available on the App Store. As study results and publications become available, they will be posted on this site and emailed to enrolled participants.
We invite anyone, health or unhealthy (with respect to sleep and other illnesses), age 18 and over to join the study.
As data will be collected primarily via the mobile application, participants must have their own (i.e., not shared) iPhone. Additionally, some data can be collected more conveniently by the app if the user also has an Apple Watch. Participants must be fluent in and able to read English, must be able to provide informed consent and be willing to follow study procedures. Versions in other languages for outside the U.S. will be available in the future.
