## Strobe tachometer (RPM meter) Description
STROBE TACHOMETER
When the flicker frequency of light coincides with the speed of any object, such as a fan, the rotating fan may appear to be stationary. Changing the frequency of the flicker of light may help detect the rotation speed.

You may easily use the flicker frequency control buttons to quickly assign the flicker frequency with an accuracy of 0.0001 Hz (0.01 RPM):

• Up to 1000 Hz (60 000 RPM) for a connected flashlight (see the video on YouTube: 
• Up to 100 Hz (6000 RPM) for the iPhone flashlight.

IF THE SPEED IS MORE THAN UPPER LIMIT, YOU MAY STILL DETERMINE THE SPEED BY FIRST MAKING MEASUREMENTS WITH A LOWER FLICKER FREQUENCY AND THEN MAKING A SIMPLE CALCULATION (AS EXPLAINED IN THE APPENDIX).

To change the frequency, you should simply press and hold the button. In the app settings, you can adjust the speed at which the flash rate changes when you press and hold the button. The flicker frequency can be displayed either in Hz or RPM.

The image you see will be sharper in lower external light.

After a long period of usage, in case of overheating, the iPhone flashlight turns off automatically.

LASER TACHOMETER
• Measurement range from 0.3 Hz (18 RPM) to 1000 Hz (60 000 RPM).
• Step 0.01-0.0001 Hz (1-0.01 RPM).
• Update time 1 sec.
• 5 mW laser power required.

MAGNETIC TACHOMETER
This tachometer operates by measuring the magnetic field from a spinning magnet. The magnetic field is measured by the iPhone's magnetometer. The magnetic tachometer is best suited for measuring low rotation speeds (from 6 revolutions per minute). It can also be used for measuring medium rotation speeds (up to 2,700 RPM), but at such speeds there is a risk of spontaneous tearing away of the magnet and strong vibration due to center-of-gravity shift.

• Measurement range from 0.1 Hz (6 RPM) to 45 Hz (2,700 RPM).
• Step 0.2-2 %.
• Update time 2-5 sec.

## Strobe tachometer (RPM meter) Reviews in United States

### ***-- "Inconsistent RPM"
I use the iphone flashlight but there is an inconsistent RPM where the flicker will stop for every second and then flash a steady light
-- Coppertone_baby, 2024-12-27

### ***** "Tattoo Machine Necessity"
I’m a professional Tattoo Artist and I use this app to know the speed of my machine. Absolutely a wonderful tool to have!
-- TatBlaster5000, 2024-10-05

### *---- "Not impressed."
Doesn’t work on 3 blade house fan. Haven’t seen it work anywhere else either.
-- SpencerRC3, 2024-06-20

### *---- "Terrible"
Don’t waste your time and money.
-- whybotheranyway, 2024-04-14

### ***** "I like it. It works"
I like it. It works
-- Thislittlecamper, 2023-12-15

### ****- "No longer available on iPad"
I had a version on my iPad for years. Last update it says this app not compatible on iPad, even though it say update on App Store!,

Developer got problem corrected. Great job!!
-- Kc2hlg, 2023-09-05

### *---- "Do not buy the photos features"
It’s just adds the rpm you had set onto a picture
-- slydilphin, 2023-06-27

### ***** "Yes"
My eye hurt
-- Baked potato tator-tot, 2022-12-29

### ***** "Amazing"
I use the free version to measure the movement of the impact head on a massage gun. Which in hertz and rpm shows very accurately.  It is very easy to work with this program. Put a contrasting mark on the mechanism that you need to measure (Rotating or reciprocating). Turn on the mechanism and turn on the light on your phone, and select the numbers by which the mark becomes stationary. Definitely five stars. Do not forget to turn off the light on your phone by pressing the button in the upper right corner.
-- Бармамия киргуду, 2021-05-09

### ***** "Industrial strobes"
I compared this application with our industrial strobes we use at work, very very close, we compare drum rpm with others controlled by VFD in a paper mill , in most every case this is exactly the same reading.
-- Russ H L, 2021-04-15
