Description

Strobily is the most accurate strobe light app on Android.

Features include:
- Millisecond precision LED flashing
- Flashing to the beat of music
- Pattern flashing
- Audio tachometer mode
- Torch/flashlight mode
- Burst mode
- Adjustable duty cycle
- Flashing with screen off

The newest feature in this app is its ability to flash to the beat of music. This is great for parties because strobe lights make music more fun!

The primary feature of this app though is its extremely accurate stroboscope ability. Uses include everything from checking the RPM of your car engine, to calibrating a record turntable, and even to finding the speed of a spinning fan. With millisecond accuracy and adjustable duty cycle, spinning objects can be made to appear stationary.

The LED will continue to flash even if you quit the app, this makes it perfect for use when you need to be visible at night. Mount your phone on your bike or carry it with you walking so that cars will be able to see you clearly.

The new audio tachometer feature allows your phone to listen to a repeating sound and discover the fundamental frequency plus any harmonics. Then with a simple button press, you can flash the LED at that frequency and watch everything freeze.

Finally, the new pattern section allows you to flash your LED in any pattern you desire. With saving and importing, highly complex patterns can be programmed.

Give it a try! There's something for everyone. Whether you're a technical person or a partygoer, this is the strobe light app you want.

A quick note about different phone hardware: This app works flawlessly on some phones and pitifully on others. Before you say "this app is crap" send me an email and I'll see if I can get it working on your phone.

Comments on Strobily - strobe light for Android

★★★★★ A. Schmitt · Jan 17, 2024

Perfect for my use cases where I need a low frequency strobe light with adjustable duty cycle

★★★★★ J FUJAK · Jun 13, 2026

No ads and works well enough to get a rpm reading. Many thanks to the guy that made it!

★★★★☆ Tom Tella · Jul 5, 2026

This is an ambitious project. Device hardware and system build matter. The diagnostic mode really helps to dial it in. I think a lot of the settings could be hidden by an "expert mode" toggle. I think a general guide about using strobes would help some people. There is a learning curve, and a device calibration curve. After that, the amount of granular control and flexibility is unrivaled. I use the strobe tachometer to experiment with fantasize animation and stroboscopic effects.

Locked up my phone (2024 Motorola Play w/ Android 13)

Showing much higher rating than actual. Domestic ceiling fans' rpm lies between 350 and 400. But this app showing much higher, at around 1000 rpm.
