Bought the app still having issues – RPM - Turntable Speed Accuracy Review

When I was using the trial it was working fine. I’d place it at the center of my TT and it would show me my results. However, once I purchased the full version, it stopped showing me my results. I’ve tried recalibrating various times but the app has unfortunately become completely useless to me :(
