Paywalling features which were previously free is a totally unfair move. You can introduce new features as much as you want, you can make them free or paid as you wish, but leave alone that what was present before. // Edit: And now annoying intrusive video ads. I increase the volume for the training, and then my ears get split by screaming ads. An absolute disgrace. Also, UI issues emerged at some point, like inadequate hyphenation and text not fitting inside buttons. I am dropping this app.

Thanks for your review! I'm sorry about the paywalling, but this is a solo project and it takes a lot of time/money to develop apps Edit: Can you send me a screenshot of the UI issues?

It really helps alot with scales and triads, but, in my school they require us to transpose melodies, if it could give examples on how to transcribe and transpose, it will really help me, and if we could change scales from treble, to bass or tennor clef it would be 1000× better, shout out the the programmers and producer, us students need more of y'all 💙

it's really a good app best of all, I think this is the best for any music student, the notes are well explained and easy to understand. but one bad thing is that u have to pay to unlock some features. But for real the app is pretty good, best app for every beginner.
