Does what it does. Got my turntable averaging 3.36 (older belt drive) while still sounding great without the wow/flutter. Needs instructions, but place device in middle of what you want, spin it. To reset avg, tap anywhere on the screen. App has no tare/adjustments so it's all on how your phone handles the gyros and send info to the app

I downloaded this app to use while I was refurbishing a vintage (1966) turntable (Dual 1009 SK). I am working on this for the 18 year old daughter of a friend. She is very interested in vinyl records, and the turntable and amp were given to her by her grandfather. I have it running properly now, lubed and adjusted. I am using the app to dial in the four speeds using my Android phone (16, 33 -1/3, 45 and 78 RPM). It is very accurate and useful for this purpose. Kudos to it's creator.

Worked great on Moto X4 and old Aiwa turntable. Used a 45 adapter to place the phone level in the middle. Tested after using this app with side by side digital vs vinyl playback. It was accurate within 1 second on a 5:34 song ~ 0.3% margin of error. Considering that level of accuracy is close to standard for recording studios, this app exceeds my expectations.
