I don't think that the drills in this app progress strictly from easy to hard. To be more specific, after I completed chapters 1 and 2 (easy mode) relatively easily, I was stuck in chapter 3 for over a YEAR. Drill 3.2 (P4, P5 harmonic) was horrible. I only barely managed to earn a passing grade on it today, after very literally MONTHS of trying. Chapter 4 got unlocked, and I immediately completed it with perfect scores on first attempt. A weird difficulty progression...

Thanks for the feedback. Unfortunately, this is different to everyone, and there is no learning curve that would be perfect for each person. It depends on many many things, including your ear previous "background" when you start the app. Do not hesitate to enable free progression and play the chapters out of order if you feel it is better for you!

It's a great app overall. My only gripe is the interval spelling exercises that are extremely tedious. I find them somewhat useless. Moreover, they would be way too difficult for somebody who's not already familiar with music theory (e.g. they won't easily understand why D double flat is jot the same as C). Making these exercises optional or, at least, providing a piano interface would have been better. After all, it's an ear trainer, not a "technicalities of music theory" trainer.

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.
