Super helpful

This app is probably the only reason HSI needles made any sense to me. It’s like a sandbox for learning instruments. Highly recommend!

Essential for IFR

Been using this app since started flying for learning IFR as well as point to point navigation. Great tool to practice and develop skills as an aviator.

Absolutely recommend, thanks to the developer.

Excellent Training Tool

I used this app on course when it was first released, it was great then as it is (even better) now. I still use it to keep my skills up after a break from IF flight/pre IRA.
