## What is Camera RPM Meter?

How it works:
With Camera:
First, mark the edge of the machine whose rotational speed you want to find. Please make sure that the machine is properly visible in the camera preview. Now, go to the app, open camera RPM and adjust the RPM using the plus, minus buttons or seek bar on the screen. Now adjust the RPM unless the rotating machine becomes stationary in the camera preview. 
Read the value from the input field; this is the RPM of your rotating machine.

With Strobe Light
First, mark the edge of the machine whose rotational speed you want to find. Ensure that the machine is placed in suitable darkness. Now, go to the app, turn it on and set the approximate value of RPM using the Plus, minus button or seek bar in the strobe light module of the app. Focus your flashlight on the rotating machine, then adjust the RPM using the bar up or down until the mark on the machine appears stationary. 
Read the value from the input field; this is the RPM of your rotating machine.

### 1/5 — Poor performance

*2026-07-04, version 1.6.9*

Light strobe is inconsistent and camera is laggy.

### 1/5 — Trash

*2026-01-06, version 1.6.9*

So many timed adds to click through, I deleted it. After 1 minute, I still wasn’t using the app. I have no idea if it works. I’m not going to click through ads every time I use it.

### 1/5 — Ads Only

*2025-12-21, version 1.6.9*

Did not make it past the ads.  It forces an add down your throat every time you change screens or hit a button.  Deleted the app before I even got a chance to see if it would do what I wanted.

### 1/5 — Too many adverts

*2025-10-20, version 1.6.9*

This is just a bundle of adverts with an app thrown in to disguise the fact that it’s just a load of adverts. 
Every touch of the screen brings up another lengthy advert
DELETED.

### 5/5 — PERFEITO!!

*2025-06-13, version 1.6.9*

Perfeito! Funcionou como eu esperava

### 1/5 — Privacy Violation

*2025-06-04, version 1.6.9*

It took too long to object to all the legitimate interests so I was unable to use the app.

### 1/5 — 用不了

*2025-05-17, version 1.6.9*

进去后没有任何功能

### 3/5 — Full power of

*2025-02-08, version 1.6.9*

Revolution I mean the whole screen occupied by the adv before you can do anything. Great work developer for adv.

### 5/5 — Works

*2025-01-20*

Y

### 1/5 — Doesn’t work.

*2024-11-17, version 1.6.9*

Downloaded it, immediately tried to make it strobe my phone’s light….. nothing. Doesn’t work as advertised.
Also - horribly frequent ad popups make it unusable. Obnoxious.
