I really liked this app. The features are great for intervals and maybe some chords, but only if you pay for the extra stuff. Honestly not that expensive considering I am using it for music school. I would recommend not getting this app if you are training for harmonic or melodic dictation, because those features are more complicated. Easy to train intervals.

Best, most complete and professional music training app on the app store. The interface is clean and straight to the point, without any unnecessary and intimidating features that may dissuade you from learning something as complex as music theory. I've had this app for a long time now, and it's an incredibly effective and fun way to train your ears while simultaneously learning music theory. I've just downloaded their new apps for rhythm and note training, and I have no complaints. Perfect.

I want to love this app but I have a huge gripe with it. They make you do harmonic intervals before you've mastered melodic intervals ascending and descending first. Making it nearly impossible to recognize harmonic intervals (at least for me). This is like teaching multiplication before the student has mastered adding and subtracting. A major flaw if you ask me. I had to use another app because I could not move forward with this one. I had to give up on this app after months(yes months) of trying to progress through this app and I could not make it pass the P4/P5 harmonic drill In easy mode. Very disheartening!!!

Thank you, but most known and effective ear training methods uses this type of progression, so it's not something specific to this app. Be sure to use a good headset as advised. Also, you can enable "free progression" in the settings and do the drills in the order you want. Did you try that? Best, Stéphane.
