Very helpful for my trans-atlantic flights.

Well made app

As someone who travels long distances frequently, this has been an excellent tool to help with jet lag.

Buggy and not well explained

The schedule input page keeps losing the data that I put in and giving me a light schedule that really makes no sense!

Needs clear instructions
Listen when I want

I am a physician and comfortable with Apps and regard this as the least clear App I have ever used. I am enormously jet lagged but do not think that is the reason. This App needs clear instructions. Is one supposed to start it several days before travel or just dive in. Why is it telling me when to go to bed tomorrow but not today. Like the idea but not the execution

Good idea, but poor execution

I like the concept of this app, but I don't think it is working correctly. I would like to start adjusting my sleep schedule while here in the states in preparation for a trip to Europe. However, I don't see a way to do that with the app (and I would prefer to not spend the first 4 days of vacation on a weird schedule). Wish this app was more useful, it is a neat idea...

Worthless

All of the 1-2 stars are right....no instructions and poor execution

I think it is flawed

I tried to use it during my recent trip to and back between IST and PST. During the flight I tried to stick to the recommended schedule and find that the app does not properly adjust to the changing timezone sand loss of hours. E.g., the hours that I carefully adjusted for the actual lighting and sleeping conditions went missing after a few hours. It might be that they got removed when the phone adjusted the tz, but that is wrong as the history is gone and will not be accounted for in the future calculation. The interface is terrible too but I would not mind as long as the app is functional.

Not very useful

I made two attempts to use this app, but I still can't interpret what (if anything) it is trying to tell me. Tapping 'Schedule travel' does nothing. Would be great if the app presented its recommendations clearly and identified what the 'Schedule' meant.

Great idea. Poor execution. Waste of time.

Traveling to Europe in a few weeks. Impossible to figure out now what I should be expecting. Have wasted at least an hour, maybe 2. Deleting the app now.
