Entrain

As people have said before, the recommended schedules make zero sense. Therefore useless.

User interface is awful and cryptic. This is a shame since I am sure it would be very useful.

Was really hoping that this would work but the schedule that it keeps giving me makes no sense. It's telling me to wake up at midnight and go to bed at 8 am when I'm only shifting four hours (going backwards). :(

Doesn't recognize that you are leaving HKG and arriving LAX same day going back across the date line ... leaving at 3pm HKT and arriving same day at 11am

Awful user interface and hard to follow

It, unfortunately, doesn't work

When I input my To & From cities, it gives the wrong amount of hours. NYC to Tokyo would never be 11 hours. Its either 13 or 14 depending on DST. Also the light schedule seemed totally wrong when arriving in Tokyo.

Does not work for me. It says that there are no recommendations to display. I travelled from Manila to Vancouver a few days ago.

More explanations about the "typical amount of light exposure" would be nice to know before I make the selection that fits my situation. We can't just assume what it means. You don't even have it in your FAQ.

Can't set my location. I'm in Tucson, always MST. Closest city listed is Phoenix, but time zone given is MST. Arizona is always on MST. Tucson is not an option.

Could not be more oblique.

Only 12 hrs in a day

Needs a simpler and less ambiguous ui

Try making it easier to use, that's the key for success. (You should fell embarrassed that a child can design an app better than you can)

Just doesnt work. 11 hour difference, tells me to shift light by 2 minutes one day then 30 minutes back the next, then jump 7 hours the last day. Nonsense.

Never let scientists design an app. the user experience will be horrible. Choose a user friendly alternative.

For a trip to Oz from UK it shows going to full light at 2am on first day of adjustment which is totally impractical for trying to maintain normal life before trip. While in theory it may work, just unusable

Hoped this would be helpful but the recommended light / dark schedule is completely impractical

Nice try...

So the advice for adjusting a 12 hour time difference ahead of time is to be exposed to light from midnight to 9am. Tell me sth that I don't already know.

So confusing

I've read the jet lag research that this app is based upon, and I am really keen to see this app succeed, but it doesn't ... It is awkward to use and cannot provide any pre-travel recommendations. Most importantly, the advice it gives is obviously faulty. Have the developers tested the app outside of a limited set of US timezone scenarios?

So confusing I couldn't follow what it was recommending... Needs to be way more intuitive.

Did not work in android

New ideas are pioneering.

Funciona, experimentei o método mesmo ainda sem existir o aplicativo e minha viagem foi muito mais prazeirosa. Praticamente anulei o jet lag seguindo a recomendações básicas de dieta de luz antes da viagem. It works better than pills. But the interface needs to improve. There is many cities missing. It doesn't preview savings time

Great concept well executed. I look forward to using it on my next trip. A few niggles I have already come across: when viewing the schedule it defaults to Detroit time for some reason. Surely it should show local time for before the trip starts and new time zone for after the trip starts. A monthly calendar view would be nice for setting trip details. Date ordering other than US month/day/year would be a useful option.

This app is a great idea and I am happy to see it on Android. I look forward to using it on future trips.

Wonderful app, great to see it on Android!

I like that the learning curve to use this app is not steep at all. The interface is simple but pleasant to look at, and it's pretty fun dragging my lighting history to update it... but maybe I am just easily amused. In any case, the optimal schedule it gave me to shift my sleep cycle back a few hours worked surprisingly well! (I stayed in the same timezone IRL but told the app I was traveling to Anchorage.)
