It works!
I used the Timeshifter app on a recent trip from Boston to London. The plan was tailored to my personal sleep/wake habits and was easy to follow. It was presented in a clear, easy to follow manner with simple instructions and information about the science behind the plan. My plan started two days before my departure day and included advice on when to get/avoid sun and light exposure, timing of caffeine and melatonin consumption (both optional) and when to sleep and wake. I followed the plan as closely as I could and it worked very well!! I was slightly drowsy part way through my first day in London, but I stayed outside in the sun and kept busy and didn’t go to bed until 10pm local time. After that day, I was completely “timeshifted” to London time. I will most definitely be using the Timeshifter app for all my future travel across time zones.

Fantastic
Backed by science, no magic portions. This really works. Thank you, team. I have been telling all my friends about this app.

No dark mode
It’s rich that an app focused on sleep doesn’t even have an icon that goes into dark mode. Simple lines of code to help our eyes stay less awake. Wild to me.
It works!
I fly from NY to Japan, and or Korea. These are long flights. This app really helps me adjust, so I'm fresh when I arrive. I'll be honest, it can be hard to stick to the plan when you're in a bright airport and it's telling you to avoid light, or there are multiple stop overs. But be as diligfent as you can. It's worth it to avoid that crippling jetlag.
Now if I could just remember to do it on the reurn trip! ;-)

Great help
Even though i wasn’t able to follow the instructions exactly while was on the plane because of the lack of caffeine and exposure to light because it was an overnight flight. I do believe the prep before I left helped.
I was expecting to feel bad the next day after the flight. But I felt good and was able to enjoy a whole day sightseeing.
