Not enough time

This is the best ear training app I have found. It has flexibility and great sound quality. The only problem for me is I did extremely well with the first steps
I mastered them right away. When I got to harmonic chords I hit a wall. I have been stuck for 6 months working on it several times a week. The requirement of 4 seconds for each chord is too short. Could you make an adjustment to 6 seconds? Thanks.
I changed my review to 5 stars. It is very challenging and most useful. Thanks, Stephanie. Any plans to add chord progressions?

Developer Response ,

Hello and thank you for your review. You should try to hear a chord as a whole, try to recognize its color. 4 seconds is really enough for this. Maybe be sure to use a headset though! If you're above 4 seconds, it means you're not totally there yet, just be patient. But if you don't want to, just use the "free progression" option in the settings. Even if we would agree on this, we couldn't change it without invalidating hundred of thousands of scores both local and on the online iOS and Android leaderboards. That would be a huge problem. Fortunately, we don't want to! :) Best, Stéphane. UPDATE: thank you! Chord progressions are in level 3 (they are called "Chord and degrees"). You can practice them by enabling "free progression" and going to level 3, in Arcade mode, or by making a custom drill. Hope it helps, best, Stéphane.

Fun and useful

I absolutely love this app and may be a little addicted. Right now I’m on Level 2 in classic mode and it’s enough to be challenging. Typically if I don’t pass the first time I will the second or third time. The levels are very thoughtfully laid out. Love that there is an easy mode for more casual learning and classic mode for advanced musicians. I have really enjoyed challenging myself and retraining my ear with this app!
