Brightness
The flash is not bright enough to be useful.
Broken
This app no longer works.
Ok
Don’t get how you are suppose to use it
Cannot hold a steady strobe light; constantly cuts out.
Very disappointed in this flawed app. The strobe light, although accurate in speed, cannot hold its light and blacks out every 2 seconds. Useless.
Awesome teaching tool!
The metrics (frequency and RPM) bring awesome demonstration to ceiling fans, house fans, guitar strings, water streams! Visual perception is so interesting as inspired by frame rates.
Erratic
On my iPhone 14 the strobe light is very erratic.
Works, but dimly
Does the job, but doesn’t set the flash to full brightness.

This app works very well and is very accurate! Very easy and quick to use, even one handed!

Perfect Strobe for Zoetropes
Outstanding app. Very accurate strobe for timing the frame rates for zoetropes. The flashes are clean also, which gives crisp animations.
I actually like how the flash is not overly bright — this shields my zoetrope animations from over exposure.
I am stunned that this superb app is free. I will check the author’s web page to see if there is a option to submit a donation.

Great app! Used every day!
Each Hertz is equal to 60 cycles per minute! 10 Hz equals 600 cycles per minute!! I love using this strobe light as it has the exact Hertz setting!
Excellent
Excellent - perfect for checking the 33/45rpm speed of my Dual record player turntable. Thank you.
Strobe light review
Love the concept however the torch light is not bright enough.
Does what it says
Simple to use, does what it says. Ideal for checking rpm of drill press, lathe, etc. Not sure if LED flash is at max brightness - had to turn workshop lights off to see things properly. Useful app though.
Erratic
LED flashes erratically, no use at all. Deleted.
Sir
Light is on lowest brightness with no way to increase it whatsoever
Consistently accurate flashes? No
Needs a fix to make the strobe flash at even rates.
Not ISO or NIST compliant; way off
We just had our centrifuge calibrated by an ISO 17025 accredited lab. It was recorded at 2515 RPM and this app reads 2664. That’s out of specification for us.
50hz brilliant
Used it to check turntable speed.
Either turntable is 0.3% slow or this is 9.3% fast - close enough for my ears👂👂

Lump of horses—t
Ruined it by putting an add in the control box. I before paid too. What a joke.
