Such a great idea, I'm really tempted purchase the pro version to show support. I can't help but wonder if my own phone has a certain amount of in built latency that is throwing off my results. Maybe a calibration mode using a couple of mirrors could help, using the signal generator and results combined. Just an idea, keep up the good work.

Nathanael Newton, 2024-06-29Finally an app like that on android. I've been playing with it for a while and I would really like to have some more explanation about what each setting (in the pro version) actually does. Also i would love to have an option to calibrate my phone. Otherwise this helps a lot with troubleshooting AV sync issues! Thanks!
