No good for multi-flight trips

Only allows 1 transit location enroute, so gives poor advice (eg sleeping whilst needing to go through security!)

Response from developer

Thanks for the feedback! Good news — we’ve since added support for multi-flight trips with multiple transit locations, so this should work much better now. Please update to the latest version and give it another try. If you run into any issues or have more suggestions, email us at support email— we’d love to hear how it works for your routes. Thanks for helping us improve!

Scam

This was supposed to be free but when following instructions it was not free. You will be charged if not careful!

Response from developer

Thanks for your message! The app was free during our AppAdvice campaign, but that promotion has now ended — sorry for the confusion! If you missed the free period, please feel free to reach out to me by email and I’ll be happy to send you a free code. 🙏 I really appreciate your understanding and support!

Free app was not a choice

Don’t bother

Response from developer

I really appreciate your feedback and I’m sorry if the pricing was unclear. The app is free to try, and optional premium features help cover ongoing development. I’m constantly improving the experience — thank you for pointing this out.

Not worth it

My biggest complaint is no way to edit or delete any trip that was created. Time for caffeine is not relevant. The usage of caffeine should be bases on person not by schedule. Presetting coffee schedule has no helps to adjusting jet lag.

Response from developer

Thanks a lot for your feedback! 🙏 The caffeine schedule is actually optional — the app asks about your caffeine tolerance at the start, so that part only activates if you choose to include it. I totally agree though, being able to edit or delete trips is super important. It’s already planned for the next update. I really appreciate you taking the time to share your thoughts — feedback like this helps me make the app better for everyone. ☕✈️
