This app perfectly replaces the need for a high end flight instrument for just a few dollars. And it makes sense, you already have the best computer/gps in your pocket.
The thermal centering tool is excellent and has significantly helped me improve my thermaling abilities. I also love how it will switch between the glide screen and thermal screen automatically.
The wind direction tool is also pretty accurate and has helped me determine the wind direction a number of times.
Battery life is good on an iPhone 11 but I do recommend using an external battery for longer flights. You can also turn the screen off which will save battery.
I even broke my vario and for a few months used the built in vario in the app. While slightly delayed compared to a dedicated vario, it still works very well. So well I’m fact, that my 3 longest flights were all accomplished using the built in vario. An awesome option as a back up vario, or for more casual pilots that don’t want to pay big money for a dedicated vario.
Also, you can change the vario sound! As someone who uses a Bluetooth speaker to listen to music while flying, this is a hugely underrated feature. Finally I can pick a sound and volume level that blends perfectly with my music instead of a clashing beep beep.
I could go on and on about the features, but
overall the app is extremely well built, performs a variety of functions, and is incredibly stable. I was considering switching to android but I think I may have to stay in the iPhone ecosystem just for this app—it’s that good. Strongly recommend to anyone who’s a paragliding pilot with a flight deck.
