You can download the app for free, as soon as you start to use the app you are hit with a £4.99 paywall that is required to use the app...


Design is nice


'free' download' not so free

Dear Nathan, We didn't intend for people to think it was a free service, and do mention the paid nature of the app in the app store descriptions. But your point is well taken. Like you, others have been surprised too, and we were reminded that we don't read these full descriptions either. As a consequence, we are going to change our model so everyone gets the first jet lag plan at no cost, giving them a chance to evaluate our service on their next trip. If you (or anyone else who downloaded the app) would like one, please contact me at mickey@timeshifter.com. Thanks for taking the time to provide us with your feedback. We really appreciate it.
This has now been changed in the app. Now, everyone will get the first jet lag plan at no cost. Thanks for your input, Nathan.
That's just awesome. Will definitely try your app on my next flight!

I was part of the pre-launch testing. I travel a lot for business, and thought I knew about jetlag. But, there is no way anyone could take the right actions to adjust without an app like this giving personalized guidance.


Easy to add a trip, easy to follow the guidance


Should be a watch app (too)

Part of pre launch testing, I had a recent trip to Milan from NYC for a trade event, have to say the app worked... hit the ground running... Talk about competitive advantage!
