About the application:

RPM Speed & Wow lets you either look at the speed of your turntable, or measure the average speed, min/max variations and wow value. Place your smartphone on the turntable the nearer to the center as possible, and you can: - begin the turntable and look at the rotational speed of it; - click "begin" on the apk and begin the turntable: the apk waits 10 seconds in order to have a steady speed, then acquires data for another 10 seconds and displays average, max-min RPM values and wow estimation. While still spinning, the apk becomes red where the turntable runs faster than the average, and blue where the turntable runs slower. The feature is active until the smartphone is lifted up from the platter. Offset correction: if you do a measure with the smartphone flat and steady, the mean rpm value will be automatically set as an offset for the next measurements. Offset correction remains active until the apk is closed and reloaded. Active Offset-correction is indicated by a text message. Click "restart" to restart the apk to do other measurement (this does not restart the offset of the current session). Click on the speed number to re-align it. RPM S & W requires that your smartphone has a gyroscope. Uses jjoe64 Graphview library. Enjoy vinyl listening! Update history: 1.6.7 - The offset correction now applies also to the text rotation. - Large bug in offset-correction corrected. 1.6.5 - Correction for gyroscope sensor offset added: if you do a measure with the smartphone flat and steady, the mean rpm value will be automatically set as an offset for the next measurements. Offset correction remains active until the apk is closed and reloaded. Active Offset-correction is indicated by a text message. 1.6.0 - Colorfest! Now the apk becomes red where the turntable runs faster than the average, and blue where the turntable runs slower. You can see where the speed changes happen. Achtung: don't worry, variations are totally normal in every turntable! - Sensor noise filtering algorithm was rewritten. - Clearer (and greener) average line in the graph. 1.5.2 - Average line in the graph view added. - Solved a graphic trouble with certain text size general settings. 1.5.0 - Major modernize! Graph visualization of the acquired data. - Better management of the sensor noise. - Increased resolution of the acquired data. 1.1.2 - Wow algorithm's resolution improved. - Minor graphic modifications. 1.1.1 - Wow calculation error notice corrected. - Calculation of the deviation from the correct speed corrected. 1.1 - Added Wow estimation! - Added 16 2/3 rpm to the recognized speeds. - Now the average RPM shows with 2 decimals. 1.0.1 - Minor modernize: controls if your phone has a gyroscope. 1.0 - First release.
