Entrain is a mobile application that uses your lighting history, activity, and heart rate to recommend schedules of light and dark. These schedules are able to shift a model of the circadian clock to a new time zone as quickly as possible. Users can opt-in to share their data with the University of Michigan for research purposes.
What's New in Version 3.4
Added more explanations, bug fixes
Glitchy and difficult to use
I tried to use this to avoid jet lag on a trip with a 17 hour time difference. On the way out, the light suggestions were very challenging. The app wanted me to avoid light during all of my waking hours and had the “seek light” time for only a handful of hours while I was asleep. On the return they app became glitchy and kept changing the times to seek and avoid light by a few minutes or a few hours over the course of the day. It was so annoying. Then it added 5 days to the cycle on the last day and I gave up.
Fix the light scheduling nightmare
The new Entrain interface is a nightmare. I've been relying on the app for years to avoid jet lag during trips to Europe and Asia. As a token of gratitude, I always submitted data to the U Mich group.
In the past, adjusting the light schedule was a breathe. Now it's a baffling horror, which must be fixed. If necessary, bring back the old version, but interface must be user friendly. Your fans and new users would appreciate it.
Love how this app works. makes adjusting and avoiding jet lag a breeze. however, there needs to be an alarm or notification to let you know when to seek / avoid light. i have to set my own alarms
