My new one-stop shop for ear training!

I teach private music lessons to a diverse client base, and this is going to be my new #1 ear training app recommendation. I just love how it breaks down different options and makes targeted drills easy to find for each learner. I’m sure I will be able to help many different people solve their ear training problems to advance toward their goals with this awesome app. And it works elegantly and looks great. Don’t change a thing!

The best ear training method out there.

I gotta say, this is an incredible app. I’m surprised there aren’t that many users, but it’s super stable, and I’m enjoying it so much. I have already achieved all the stars in the beginner section and I’m now half-way done with the chords section.

I use the app every morning and every evening, on my commute to work and I have definitely noticed my ears getting so much better.

And THANK YOU for no ads. I hope it stays this way.

I would love it if there was a plain piano feature. I have a separate piano app, but I would definitely get rid of it if a piano section with no objectives would be included.

I will definitely share this app with my musical friends.

Bravo bravo, simple elegant ear training

Absolutely flawless, clean design with wonderful scaffolding of interval, chord, scale, and tune training. I’ve tried many ear training apps and this one is the best — and free! I especially love the Charlie Parker tune tests — a great way to check improvements in interval recognition!
