Tonic is the most fucked up app on iOS. It just straight up internally dies. As soon as you try scanning the piano it scans it in the wrong plane and doesn’t scan like the picture wants it to. Then it asks you to map the first key of the piano and it moves the key vertically instead of horizontal. If you scan it the other way it does the opposite plane. I just want to try a cool app for my phone and you call your app a functional app. How.
