I have created an Android app called "Chime Ball."

The idea for this app = SUPER SIMPLICITY, for kids. Balls are dropped into a play area which can be arranged on a stealthy treble clef-ish shelf system. Intended to make understanding Western note and timing relationships simple and fun.

I picture this as a short activity for the musically-minded kid. If you'd like to join my Google Play Console-based closed testing team, just follow the link at the top of this post. Thanks so much!
