### 5/5 — Must have app

*2023-11-11*

Quick and simple to use a must have for pilots

### 5/5 — Great app

*2023-04-07*

Great app does exactly what it says very straight forward, also references the CARs section it takes it’s data from.

Would be great to see an Apple Watch app or a widget for iPhone would make this great for quick referencing your duty day and time remaining.
