Does not work The app is extremely sensitive and when viewing a cloud top, the scale will jump between 3.5 to - 2.0. Even when I would sight in a cloud that was obviously above me, the app would say I would top it. I used it on a 4 day trip and could never get an accurate read out
Needs ability to adjust back lighting of the numerals. It's to difficult to see inflight!!!
Simple to use yet feature-full navigation, logbook, flight recorder for pilots.
