I really was liking this app for clinic to hold kids attention. But now the animals scroll upside down no mater what orientation I hold my iPad. I tried unlocking and locking the screen orientation but it did not fix the issue. Frustrating. I wish the developer would fix this glitch.

This is fantastic as a tool for vestibular rehab! Is there a way to make it a 360 immersive video version—where it looks like you are in an optokinetic drum (compatible with a phone VR headset) to use for patients with MdDs?

The flow is not smooth at all very jerky like it is glitching. This does not function as it should. The metronome doesn’t work. I can’t change the direction of flow. I’d like a refund
