Piano Ear Training

Can't get any sound from this. Tested sound using others apps, music, movies, etc... All worked. Reopened app and still no sound. Contacted support, they suggested sound might be muted. Deleted app, reinstalled, same result. No sound. Looks like a well designed app. Would love to use it. Unfortunately, with no sound, it's unusable. Update - tech support worked with me to fix this. After checking the volume and every other sound setting I know about, there is a mute button I didn't know about. The directed me to it and there is sound using the app now. Why Apple allows sound from other apps when the mute is enabled is a mystery. Regardless, it's working now thanks to tech support.

Very easy to use

The app has great ideas. It looks amateur, and crashes constantly. When receiving g feedback on your answers the feedback immediately shows up and disappears leaving no time to know why you got the answer wrong. Very buggy app but good sound quality and useful concept.
