I wish this worked as well as I had hoped, but I just have a hard time imagining my students using this without a ton of guidance. You need to listen to their rhythm, catch the pulse, tap the pulse, then mimic the rhythm at exactly the right tempo without any aid from a metronome.
When repeating the rhythm, there is a small circle that appears when you touch the screen and grows into a larger circle. I am always a bit unsure of what registers as a “touch” when using rhythm apps like these, and this is effectively a visually deleted effect that makes it worse.
Similarly, a small circle grows and changes color with each beat of the rhythm that is to be imitated. Same problem; it obfuscates the beat.
In my studio, by the time a child is experienced enough to overcome these obstacles, this app is not challenging enough.
