## RPM Description
The best Turntable RPM accuracy test mobile app available.

See the RPM speed variations, know as wow/flutter, of your turntable in real time graphics like you've never seen before, continuous display makes it easy to make adjustments as necessary if your turntable allows it.

Test the RPM speed and wow/flutter accuracy of your turntable, whether 16, 33 1/3, 45, or 78. 

And now with the Worldwide RPM Turntable Accuracy Database you can research what other RPM users are finding out about their turntable's accuracy and what they think of them. 

  ●  RPM is proud to be recommended by Rega Research Ltd, makers of some of the best turntables in the world.
  ●  Great review by Techmoan on Youtube
  ●  Used in high end TT reviews in Stereophile magazine

See the wow/flutter accuracy as the max % deviation from the average rpm of the turntable, as well as graphically in the chart.

Save all your rpm test sessions to the history log for review or sharing later.

RPM uses the gyroscope in your iPhone to determine the rotation speed of your turntable, automatically determines which speed setting you're on, and reports how accurate it is.

Simply place your iPhone on your turntable, close to the centre but doesn't have to be over the centre spindle.   As the iPhone rotates the display will remain stationary from your perspective for easy reading.

The UNIQUE feature of RPM is that it shows a scrolling graph of the rpm accuracy variation over time, this shows wow/flutter effects, especially those associated with the turntable not being level, belt wear, etc.  You can even detect the small drag caused by the stylus resting in the grooves of the record.

The most recent amazing new innovative feature is to visualise wow and flutter variations plotted around the vinyl centre to show a heat map of exactly where in the turntable rotation inaccuracies occur. 

There are many ways of testing the average RPM of your turntable, some turntables even have this built in, however there is no other practical way of showing the wow/flutter variation over time than RPM.

The history graph parameters can be customised to:
 - Set the moving average sample size.
 - Accuracy at which to turn the rpm circle sold green.
 - Set a duration after which the display updates will freeze so they can continue to be read after the turntable is stopped.
  
The RPM realtime display is reliant on the iPhones gyroscope accuracy, if you suspect yours isn't quite right then you can now use Calibration Mode to auto test and then apply any necessary correction in real time.
This auto calibration uses the compass to count the turntable revolutions, if you have an older iPhone (not iPhone 6S or newer) then this may be unreliable, in this case you can still add your own multiplier if you have done an independent calibration.

Extensive testing means we're now confident that using RPM can help you setup your turntable to be within 0.1% of its target RPM, assuming your turntable can be adjusted and is itself stable within that tolerance of course.

The World RPM Turntable Performance Database now has over 10,000 submissions from RPM users worldwide to build the ultimate resource for researching the most accurate turntables out there.  Upgrade to join in and upload your own turntable data, go to Settings and make sure you have the Freeze time set then do an RPM session as normal.  At the end of the time you will be asked to name your session after which you will have the option to also upload it to the World DB.  You can always upload from History later too.

Upgrade to enable unlimited measurements, continuous display, all settings, all speeds, no ads.

## RPM Reviews in United States

### *---- "Greedy"
$15 payment needed after 10 uses. For an app that shows how fast your turntable is spinning. A real greedy loser is behind this app - DO NOT SUPPORT THEM
-- AcePhoenix007, 2025-01-02

### ***-- "Good but can't save??"
It's nice to see what my vintage turntable is still able to do but not being able to save my results and needing to pay $15 for the full app is kind of too much
-- adrianpriv, 2024-10-24

### ***** "Quick and Easy"
Super easy to use. Love the helpful tip of using a tape roll and the rotation lock feature. Nice touches that show thoughtful design.
-- Calwoot, 2024-09-27

### **--- "Wasted Money"
I liked the free version so much that I paid $14.99 for the upgrade. Big mistake. None of the pay to play functions actually work: freeze display, history, etc. What a waste of money.
-- Douglas1001, 2024-06-15

### **--- "Not accurate. At least on my iPhone 13 Pro"
This app had me very confused. Had all of my tables running fast with extremely high wow and flutter.  Now I know my quartz lock Technics SP-25 and my Pioneer PL-550
Run dead perfect. Used my prior app and it noted a perfect 33.33 for both of them. Tested my direct drive Luxman PD-277 and again, very close at 33.30. This would be my expected results. I’ll be deleting this app.
-- BenDover4Dover, 2024-01-29

### *---- "This is only a TRIAL VERSION!"
After 10 tries you have to BUY IT. They don’t tell you that in the description.  Had I known this I would never have downloaded it!
-- Veryoldmusic, 2023-12-31

### *---- "Utterly useless"
History doesn’t record without paying $15, don’t waste your time.
-- George78955, 2023-11-11

### ****- "Love the app but it won’t let me save any more"
Got a new turntable, and wanted to save it to my history and share it to the database. But for some reason, my app no longer allows me to save new turntable data. I deleted a bunch of the duplicates I had submitted thinking I might’ve reached my limit, but that’s not the case, because even with just a few measurements in my history, it no longer allows me to save new measurements. I’m sure it’s just a short term bug.
-- Wembely, 2023-10-03

### *---- "Obnoxious Paywall"
The app doesn’t for long enough to be useful before it interrupts and tries to get you to buy the app, over and over and over again. So obnoxious. Deleted.
-- cmeerdo, 2022-12-13

### *---- "Don’t"
You’ve got only 10 “tests” then 15$ to upgrade.
-- argusor, 2022-12-04
