The teaching system is awesome but there's something I'd suggest you do: For each exercise, it would be better if you sticked to a particular key because picking random chords from different keys in one exercise is really confusing 😵‍💫. Sometimes I'm correct but the the system tells me I'm wrong. Please fix that 🙏🏿, I really want to make progress here because it's important to me and you guys made it possible. Thank you ❤❤

Thank you for the feedback. Unfortunately, that's exactly the opposite. The goal at this point (when you are learning to recognize a specific chord) is to hear the "color" of chords regardless of its context. It should absolutely not be done in a specific key, that would go against everything that makes these drills work. Best, Stéphane.

Very good training app. I purchased full version already. The scoring and progression system is a bit unfriendly for beginners. I don't want to unlock all levels in settings (I know about this feature). I still want to collect stars and unlock levels as I progress... But even though I get 31 correct answers out of 32 questions - it's still 2 stars... And I need 3 to "pass". It would be nice to remove timer completely and keep score for amount of correct answers only.

I love this app and I've been using it a lot. I plan to buy it as soon as I can afford to. I just have one bit of feedback for the interval recognition, would it be possible to include a "play first note longer" option in the settings. I'm really struggling to make progress and I think it would help. Love your work, I'm also using the complete rhythm and complete music reading trainers!

Thank you for the feedback. Unfortunately, as there are leaderboards for the app, we cannot. But you can easily create custom drills to have the same exercices as the classic mode but with a slower tempo. Hope this helps, best, Stéphane.
