It didn’t work. After inputting all the numbers, II press calculate, and it does nothing. Like it freezes. Terrible. The old original one is way better. ### 1/5 — It used to be great. *2026-03-10* It’s sad to see a great app being redesigned to a terrible app. Make it simple again. ### 5/5 — Easy & works *2025-05-17* Designed for PILOTS flying as augmented crews, the app allows for 2/3/4 even breaks and has options for a buffer between periods if necessary. The app works well and is easy to use. ### 2/5 — Not for any flights with a mid flight service *2024-09-17* It only allows up to a 15 gap between rests, and there in no where to enter a mid flight service, so for us it isn’t useful. ## Frequently asked questions about Crew Rest Calculator ### What is Crew Rest Calculator?
