Turn your phone into a strobe light that flashes to the beat of your music. FlashBeats drives the LED flashlight on every phone in the room at once so a single tap fills the whole space with party lights.

No speakers to carry no lamps to hang no setup. Start a track and every connected device becomes part of the same light show.

WHAT THE APP DOES

Music-synced strobe light. The app reads the track you pick and fires the LED flash in time with the rhythm. Fast beats give you a rapid stroboscope slower ones a soft pulse you can sit through all evening. This is what turns an ordinary phone torch into a DJ flashlight.

Unlimited phones in one show. Connect as many devices as you like on the same network. Every extra phone is another light source and the more you add the brighter and louder the party gets. They flash together instead of drifting apart.

Your own playlist. Build a list from your favorite songs and the disco lights follow it from the first beat to the last. The room fills with club lights that pulse to whatever you chose not to a fixed pattern.

Microphone mode. Point the phone at whatever is already playing. The microphone picks up the ambient music and builds the flashing lights from what it hears so the strobe works with a live band a car stereo or someone else's DJ set. Nothing needs to be connected to the source.

Tap to light. Build a pattern by tapping the screen and the app repeats your rhythm. Useful for a concert lighter effect a slow pulse late in the evening or a countdown at midnight.

Color light and UV mode. Beyond the LED flash the screen itself turns into a colored strobe — red blue green purple — and an ultraviolet lamp mode gives the room a different look. Tip: set display brightness to maximum for the strongest color flashlight effect.

Live video streams. Join one of the streams our editors put together — EDM hip-hop rock pop and more — and watch along with friends while the flashing lights stay in step on every phone in the room.

Volume booster. Audio and video stay aligned across all connected devices so a row of phones works like one sound system instead of an echo chamber.

Party leaderboard. Invite friends into your session and see where your group lands worldwide. The more people flashing together in one party the higher you climb.

GETTING STARTED

Open the app pick a song and the flashlight starts strobing on the first beat. That is the whole setup. To turn one phone into a room full of light put the other phones on the same network and let them join the session. Nothing needs pairing and no cables are involved.

WHERE PEOPLE USE IT

House parties and birthdays where a phone strobe stands in for a rented disco ball. Concerts and stadiums where a whole section lights up on the same beat. Dorm rooms small clubs and rehearsal spaces that need light effects without hauling equipment. Open-air gatherings where there is nothing to plug a lamp into. Anywhere the lights are already down and the only equipment in the room is the torch everybody carries in a pocket.

HOW THE SYNC WORKS

One phone starts the party and the rest join it over the same network. The host picks the music and every other phone follows the same beat so the whole group flashes as one strobe light rather than a dozen separate torches. If someone walks off mid-song their phone simply drops out and the rest keep going.

FlashBeats is built around one idea: the flashlight already in your pocket is a strobe light waiting for a beat.

SAFETY — PLEASE READ BEFORE YOU START

The LED strobe light is bright by design. Rapid flashing may be harmful to eyesight and it can trigger seizures in people with photosensitive epilepsy including people who have never had one before. Do not point the light directly into anyone's eyes. Stop using the app immediately if anyone nearby feels dizzy disoriented or unwell.
