Stroboscope app for measuring rotation, vibration, oscillaton or reciprocation
Pros & Cons
Combines strobe light and optical tachometer in one app
Calibration and adjustable duty cycle improve measurement accuracy
Image capture and automatic saving of measurements
Quick turntable speed presets (50 Hz/60 Hz) for common use cases
Lacks some features common in competitors (e.g., built-in LED flashlight and tuner functions)
Maximum tachometer frequency is limited to 30 Hz (1800 RPM), which may restrict high-speed measurements
Not ranked in top app lists, indicating a smaller visibility footprint

Description
Stroboscope app and optical tachometer for measuring rotating, vibrating, oscillating or reciprocating objects. Optical tachometer can be used by starting it from MENU - TACHOMETER.
It is most commonly used for: - adjusting speed of rotation - for example adjusting speed of rotation of turntable - adjusting frequency of vibration
How to use: 1. Start app 2. Set frequency of strobe light (in Hz) using number pickers 3. Press ON/OFF button to start the strobe light
- use button [x2] to double the frequency - use button [1/2] to halve the frequency - use button [50 Hz] to set frequency to 50 Hz. This is for turntable speed adjustment. - use button [60 Hz] to set frequency to 60 Hz. This is also for turntable adjustment. - activate duty cycle by checking [DUTY CYCLE] check box and adjust duty cycle in percentage. Duty cycle is the percentage of time per cycle when the flash light is on. - optionally you can calibrate the app by starting calibration from MENU - Calibrate. It is good to do calibration when frequency is changed. You can also set correction time manually in Settings.
Accuracy of the stroboscope depends on latency of your device flash light.
Optical tachometer can be used by starting it from MENU - TACHOMETER. It analyzes moving objects and determines frequency in Hz and RPM. How to use: - point the camera to the object and press START - hold steady for 5 seconds - result is shown in Hz and RPM
You can save images captured during measurement by clicking on disk icon. At the end of measurement a message will be shown with information how many images were saved. Images are saved in folder Pictures/Stroboscope. The name of the images ends with information how many milliseconds they were taken relative to first picture. You can use this information to determine the object RPM by calculating time between similar images.
Minimum and maximum frequency can be set in SETTINGS - TACHOMETER. Increasing minimum frequency will reduce time needed for measurement. Maximum frequency is 30Hz (1800 RPM). Reducing maximum frequency will improve time needed for processing during measurement.
Recent changes: Stroboscope app v11.6 - Android 15 ready v11.5 - Added optical tachometer. Use it from MENU - TACHOMETER. The app analyzes moving object and determines frequency in Hz and RPM. How to use: - point the camera to the object and press START - hold steady for 5 seconds - result is shown in Hz and RPM v10.8 - add up to 5 buttons for fast setting of favorite frequencies or RPM - alternative strobe method in Settings - Use alternative strobe method

Great simple app that gets the job done (but not in sunlight). I used it to check the idle speed on my outboard. A bit of white duct tape on the flywheel and in twilight it worked well. Phone LED's are not bright enough to use in sunlight, and they aren't brief enough flashes to give a true photo grade strobe effect, but it got the job done. Ads are not obtrusive. An improvement would be a bigger frequency slider. It's hard to get the right spot when you are looking at the strobe device.

Impressively accurate strobe light compared to other apps. Perfect to measure electric motor rpm. The only app I've found that can actually measure rpm.
★★★★★Derrek Leiter· Feb 15, 2022
I am impressed that it can turn the phones led on and off fast enough to measure around 3krpm. Nice!

Worked well to check my turntable with a strobe disc.
★★★★★Zachary Varnum· Dec 7, 2022
Great little app! The strobe light on my turntable burned out and all the lights in my house are LED. I was able to use this app to adjust the speed.
★★☆☆☆Aaqil Khan· Oct 30, 2021
Tried it on motor and didn't give accurate speed measurements. I had to borrow an actual stroboscope to do the job.

Newest version locks up my phone. Complete reboot required. I hate not being sble to revert to previous version of an app!
★☆☆☆☆Daniel Gunn· Jul 26, 2024
Does this app require reflector tape? I want to use it for checking RPM's on an output shaft on pumps, the range will be 400-1725 ×/-.

Trash. Light doesn't stay on or goes full on when using it. I installed it and shortly uninstalled it.
