Used by astronauts, elite athletes, and top CEOs, Timeshifter is for travelers who want to eliminate jet lag.

It’s developed with Harvard Medical School Associate Professor Steven Lockley, Ph.D., and based on the latest research in sleep and circadian neuroscience.

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...

Pros:

Design is nice

Cons:

'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.

This is great - I just downloaded as I am very bad with jetlag! I wish I had a way to try before I have to pay.

@mickeybc I think it should be freemium as an example of 'spotify' where people could feel how an app could help em for shorter amount of period which would trigger them to buy an app or people who want to use free services (which is not there right now) will be using your app because their needs are enough according to free services.

@mickeybc WOW, thank you for such an immediate action to my feedback. I have recommended to my friends who travel internationally and they must appreciate that they are able to try out the feature before they subscribe. I can't wait for the next travel without the stress! Thank you again Timeshifter - this kind of action makes me become a fan. Wishing you the best!

I have been traveling between US and Asia for 10 years and had the worst jetlags. This is so helpful! I featured it on my new travel resource site that just launched. Feel free to check it out and let me know if you'd like any of the info changed~

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.

Pros:

Easy to add a trip, easy to follow the guidance

Cons:

Should be a watch app (too)

Cool app! I think it will be useful for many students. I graduated from ( https://www.trinityschoolofmedic... ) caribbean medical student and I can advise many students, especially doctors, to plan their time and keep track of time. From my point of view, this is the area in which we should invest the most because of its importance to society. When I moved to train as a doctor, it was very difficult for me to adjust to the time, but I think this application would help me very much. I'm wondering how this app has influenced you and how it has helped you in life?

Timely. I'm flying to NY today, Canada next week. ✈️

@rrhoover Hi Ryan - We would be very happy to learn about your experience with the app. Please do not hesitate to send feedback along the way – praise is great, critique even better ;-)

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!

In fact, in medicine, the most important thing is the desire of the student and the desire to gain new knowledge

The app user experience is meh, but an even bigger issue for me is the company's ethics. They stole one of my photos and used it without my permission on their site for 4-5 months. When I had attorneys send them a demand letter asking they pay commercial licensing fees for the image, they did not pay.
Michael Nilsson
That's just awesome. Will definitely try your app on my next flight!

Hope this works. Fingers crossed :)
