Voice Teacher - Sing in tune

The app starts off fine asking you the right questions, but the actual app functions doesn’t provide feedback. A dot starts moving across the bottom of the screen with no feedback on what is happening. I tried 7-8 times to understand what it was telling me to do and gave up

IIIIy

I literally just installed this app and i love it already but i get get past a single practice without it crashing and closing out on me. I see great potential in this except for those crashes

It crashes way to much
