SmartMusic

The SmartMusic Inbox app is a waste of your time and and makes all musicians want to destroy their instrument. There are many reasons for this.

1) This app/website doesn't allow you to breath if you play a wind instrument unless there's a rest (on many exercises there are no rests ie scales). This app registers the note if you shorten it at all to sneak a breath.

2) The tracking mechanism is completely broken. The note you play correctly, for example a B flat, could be tracked as a G)

3) If you want to find some music to play for fun on its search bar, more chances than not, it won's show up.

4) The tracking of how long you have practiced is also non-functional. For example. if you practiced for 30 minutes, 50% of the time, it won't track properly

With these points put into consideration, I sincerely hope you will stay away from this app until the developers decide to improve it
