This group of apps are flat out the best thing I have found for learning to hear intervals and read sheet music and rhythm notation. You need all 3 apps for real they are so fantastic that it will be hard to put them down. It is so much harder to learn ear training than you might think this app helps so much. I honestly rate it in the top of its class. I love the apps

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.

One of if not the best ear trainer available on phones. Greatly helped a university to pro level musician tune in his ear and upgrade his theory skills.

It's not a COMPLETE ear trainer, it's a partial ear trainer locked behind a paywall

This is a great app. Though I'm experiencing a glitch where the app just doesn't play the sound. It's really annoying when I'm nearly done with a level, and it just can't load the sound. I'm using Samsung Galaxy. Please fix.

It's not very efficient for beginner. Sad Fact, I stuck on chapter 1 easy mode for almost 2 years. I only persevere because I paid the app. It still feels waste of money though. Only when I start to learn Solfège song this month, I managed to get 3 star and continue to chapter 2. Suggestion: Having Solfège training in the app would be very helpful.

Nice app but so frustrating I'm stuck on"easy level" 3.5 despite putting hours in. When I get it wrong and get the app to play the notes that I was meant to hear, they just weren't there for me in the original, on my phone speakers or my nice headphones, they just aren't there. If I'm listening for a fourth but not getting the root, then I am getting the fifth to the harmonic at the octave. How am I to guess what notes are missing?
