The light suggestions are interesting and sometimes counterintuitive. When I often thought it would be best to get up early and force myself into local schedules, the app would say otherwise. When I followed the app, I generally felt better. Problems: - it has a place for Apple Watch data but there is no way I can discern to actually allow the app to use that data. - in the space of 5 minutes the suggested time that I was supposed to seek light until changed by hours. Not sure what happened there.

Very confusing to use. I was hoping to use this app to counter long jet lag adjustments on my trips between Eastern and Western countries. Unfortunately I’m so confused about the time notation, and it makes me feel quite stupid. If I’m following correctly, the the app is simply suggesting that I avoid light for 12 hours and avoid dark for 12 hours each day for about 4 days, and then (hurrah!) my schedule is complete. BUT the daily suggested schedule is only maybe 30 minutes off my final target sleep/wake times. Really? Maybe the schedule is this way because of the complete reversal of day/night in Eastern and Western countries, but I didn’t need an app to tell me to just force myself to be awake during the day and asleep at night to adjust. OR maybe I’m a complete dunce and I’m reading the time notation wrong. If that’s the case, how does being awake at night for days on end somehow magically help me adjust in 4 days. Its just a little muddled and unclear in the delivery. The jet lag o...

As a frequent traveler (2-4 trips per month, US-Europe, Asia, & deep South America), I was excited to learn about an app like Entrain. I’m just using it on my first trip and noticing some basic omissions and, what appear to be, some bugs: 1. Upon installation, there was no tour or tutorial explaining how to optimally use the app; only a few questions. 2. There aren't any recommendations on when to start “adjusting” prior to starting a trip. 12 hours prior? 24 hours? 3. There aren’t any notifications (badges, alerts, etc) for when a “seek light/dark” period is starting. Also, no Apple Watch integration for the notifications. 4. (Bug?) The “seek light/dark” times keep changing. Sometimes by minutes, sometimes by hours. Sometimes in the middle of a period. 5. (Bug?) When setting a trip end time, it changes the time to other than what is selected. For instance, our arrival time was 10:50a (GMT-3). The app kept changing this to 12:50p (GMT-3). 6. The UI for changing the “Normal ...

There seems to be a bug in setting up your regular schedule. I accidentally set my wake up time as 6:00 PM instead of 6:00 AM and it wouldn't let me change it later. Every time I changed my wake up time, it would reset back to the original value. I had to delete the app and then reinstall it. I'm not sure I agree with other saying that is too technical. The app shouldn't be required to give you definitions of things like LUX. However, like others, I find it difficult to determine what it's trying to tell me to do next. It'd be nice to have a link to a 2-page "how to" document.

I followed the directions to the letter, though difficult on a flight from Australia through New Zealand, ending up in San Francisco. Aside from a few uncomfortable moments, my jet lag was minimal. A good tip is to use a light box to help with the “seeking light” part of the program as I returned in winter, and it still gets dark early in SF. The program is greatly improved in simplicity since I tried to use it last.
