Love everything of this app. However I would recommend to introduce a way to change the color palette. While it is immediate the difference between white and yellow highlighted keys, it is very difficult to me being able to distinguish between black and brown highlighted keys. Maybe introduce a color inversion: white to black and black to white if not possible to add a new more visible color. Thanks for the app!

I need a monthly subs to access other scales? Just make it 10 bucks and I’ll buy it. There is zero need having to pay monthly.

You hear and see what you play. It helps to sink it into your brain the way it is set up. What more do you want!? 5 stars. Thanks for making this.

This app does everything you need, without extra nonsense. A++ exactly what I was looking for.

Amazing app for piano players beginning to learn their scales and chords. Literally has every scale and chords and amazing learning game to help u memorize it

I like it and I expect it will be a significant help in learning basic music theory so I can have fun in the process too. (I initially had a little trouble getting the sound going but this was not the app's fault. My privacy setting was on and this muted the sound.) Thanks for such a useful app.

For free playing it is awesome

It's just what I need. Has the notes on the scales highlighted and labeled so you can easily play the scales and notes you need.

I wish that I could go over all inversions in all keys continuously and not be limited to the 12 that are randomly preselected for me. Or perhaps, I am able to select what keys I want to test on. Also to be able to review what you got wrong in the would be helpful. Good app!

You showed the whole keyboard and interesting to see all of the keys at once
