Check 33, 45 and 78 RPMTurntable Speed: RPM Meter
Lay your phone flat on the spinning platter and tap Start. Turntable Speed waits for the platter to settle, times five whole turns, buzzes and holds the result, so you read it after you pick the phone up: the RPM and how far it is from 33 1/3, 45 or 78. Each reading is checked against the phone's compass, which goes round exactly once per turn.
Free: held, compass checked readings at 33 1/3, 45 and 78, and a result card. Pro is a one-time purchase that adds history for each turntable, a fine-tune mode, a wobble graph and more speeds.

Questions
Is Turntable Speed: RPM Meter free?
Free: held, compass checked readings at 33 1/3, 45 and 78, and a result card. Pro is a one-time purchase that adds history for each turntable, a fine-tune mode, a wobble graph and more speeds.
What does Pro add?
A one-time Pro purchase adds history for each of your turntables with CSV export, a fine-tune mode with a big FAST or SLOW cue for setting a deck's speed, speed wobble and a graph of each measurement, extra speeds (16 2/3, 78.26, 77.92 and your own) and Brass and Night card styles.
How accurate is it?
Phone motion sensors can be out by a percent or more, so each reading also times whole turns with the phone's compass, which goes round exactly once per turn whatever the sensor's own error. The app learns your motion sensor's error from these checks. If a magnet near the platter blocks the compass, the app tells you and uses the corrected motion sensor instead.
Do I have to read the screen while it spins?
No. Leave the phone on the platter until it buzzes, then pick it up. The result stays on screen.
