## What is True Note?

Use True Note to test a record player to see if it's playing at the correct speed.

Here's how:

1. Download the True Note app and open it
2. Print and cut out the included turntable strobe disc
3. Place the strobe disc on your record player and start it at the 33 1/3 RPM speed
4. Tap "START" in the True Note app and shine the flashing LED light from your iOS device onto the strobe disc

If your record player is playing at the correct speed, you should be able to make out the individual lines on the strobe disc - and they should appear to remain in the same position (not drifting in one direction).

Many record players have an adjustable speed and can be calibrated with the help of True Note.

Perhaps you're shopping for a used record player? The True Note strobe disc is small enough that you can fold it in half to keep in your wallet or iPhone case - ready to use when you're at a thrift store or garage sale and want to make sure the turntable you're considering buying works properly.

### 5/5 — Strobe light works perfectly

*2026-07-22*

The strobe light works perfectly with my physical stroboscope disc that I already owned. Wasn’t able to print the stroboscope disc through the app but that wasn’t needed

### 5/5 — Not idiot proof

*2023-02-09*

In order to use this app properly one needs to know if they have a 50 or 60 hz motor.   I downloaded and printed the proper speed checker.  Preprinted speed disc are also available for 15-20 through mail order.  When done properly this app works totally gets the job done.

### 1/5 — I need a printer? Seriously?

*2022-03-09*

I wasn’t counting on needing a printer to use this.

### 1/5 — Incorrect on iPhone 13

*2021-11-05*

Does not produce correct frequency, at least with an iPhone 13.

### 5/5 — Great for Empire Turntable Owners

*2021-08-11*

This app is great to ensure that my 1975 Empire 598 III Troubadour turntable is spinning at the proper speed. Since there is already a strobe disc built-in to the center portion of the platter for both 45rpm and 33 1/3rpm, the 60hz strobe light setting within this app lets me adjust the rotational speed properly until it is locked-in completely for proper playback. Other apps will give you ballpark figures, but only a strobe will give you a proper reading every time. Highly recommend to turntable owners that already own strobe discs or platters.

### 5/5 — Perfect

*2020-07-14*

Very simple, easy to use. Sorted the speed on my Gyrodec in a couple of mins. Thank you.

### 5/5 — Funktioniert perfekt!

*2020-05-03, version 1.2*

Tut das, was es soll.

### 5/5 — Great App

*2020-04-30*

This was the only app I found that actually helped me fix my turntable. It was straightforward and quick to use. I wish it included a 45 rpm strobe disc as well, but I was able to find one online.

### 5/5 — Works great!

*2020-02-10*

I didn’t try their strobe disc, but the strobe matched up accurately with the one on my technics turntable.  Pretty cool!

### 5/5 — Works fine

*2019-11-05*

I have the app on an old iPhone 5 and it works well. Very useful free app.
