"These two apps (Treble Cat & Bass Cat) are excellent for students to practice identifying notes on the staff. It is a great pair of apps to recommend to parents/students to use at home. I love how simple the concept of the game is — even young piano students will be able to independently use this app."

Please do a grand staff version

I have been using the bass and treble versions of this app in my piano studio. The kids love it, but I wish there was an advanced level that included bass and treble in the same game. It would have much better direct relation to piano than two rows of treble or two rows of bass!

Great for students

I love using this game with my piano students, but I would like a version that starts from the top down. That way it matches up with the order of the notes they learn.

Love it!

I love that you can play any level multiple times and each time is different. You can unlock the levels which is nice if you want to skip ahead. I would like to have the option of adjusting the speed in order to increase the challenge. The sound is totally unnecessary and distracting because it has nothing to do with what you are playing, but also it's great that you can play silently without headphones (like if you are in a doctor's waiting room). The words "Level Failed" are discouraging and should be changed to "Try Again", like in Rhythm Cat.
