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.
