RPM Record Player Tester app analytics for January 6

This is a reasonably simple app to test/compare your turntable against the correct speeds. It will always counter rotate the display such that the RPM value is visible whilst measuring. This app also records your RPM data in graph form for you to review and optionally save after any given run. You can view your saved previous runs, which allows you to analyse any wow/flutter your turntable may have. There currently exists other apps that accomplish this, but they're either rudimentary, ad supported, and free, or are professional with more features but cost more to unlock all features. With this, I hope to provide a simple app that does exactly what it says on the tin, with some extra lovely features, for a cheap price that once paid you own forever. However, feel free to use the other apps if they suit you better! Any issues, feel free to contact me!
