1. It was never useful at all...my sound is loud so i tried using this App to play in tune and it keeps on saying im playing in tune.
2. Whoever made this App should do some research on saxophonesClick on tuner gives advertisement that will not go away.
3. Its also written in concert pitch which is very inconvenient.
4. Even when everything is silent, it still detects notes.
5. Just really awful.This App was not designed by a Professional Saxophonist.
6. This app just con you into clicking on advertisements for developer to make money.
7. There is no tuner here.Yet another app that calls itself a saxophone tuner and yet shows notes in concert pitch.
