Turn the phones in the room into one big speaker. No cables, no bluetooth pairing, no waiting for anyone.
Starting one needs an account — 3 days free, no card.
Joining one needs nothing at all: a code, and you are in.
How it works
Nobody downloads an app to join. Nobody signs up. Nobody waits.
Tap once. You get a short code and a QR, and you are the one who runs the music.
Point a camera at the code, or type the six characters. That is the whole joining process.
Every phone starts on the same instant and stays there. Put them around the room and it sounds like one system.
Why it stays in sync
Messages arrive late, and differently late on every phone. So we do not send them. Every device is told the instant the music starts, measures its own offset from a shared clock, and works out for itself where the song should be. A slow phone is not a late phone.
Each phone measures its own offset the way NTP does, then keeps measuring. Being on a different network changes nothing.
No two sound cards run at exactly the same speed. Each phone learns its own and nudges playback rate to cancel it out.
Whoever starts the party controls the music. Hand out control to anyone you like, and take it back when the aux-cord thief appears.
On a limited plan? One switch fetches one song ahead instead of three. The sync is exactly the same.
Parties are held on whichever of our servers answers your phone fastest. Shorter hop, steadier clock, tighter sync — wherever in the world you are.
FAQ
No. Everyone needs an internet connection and that is all. Phones can be on wifi, on mobile data, or on completely different networks.
Yes. Nothing in it is tied to a country. When you start a party it lands on whichever of our servers answers your phone quickest, so the clock every phone measures itself against is a short hop away wherever you are. A party is a room full of people standing together, so all the traffic stays local to that room and nothing has to cross an ocean to keep the music lined up. The app is in English today, and prices are shown in your own currency through the store you installed it from.
Two to six is the sweet spot for a room. It works well well beyond that, and the practical limit is the wifi in the room rather than the app.
Only the person starting the party. Guests scan a code and are in, with nothing to install and nothing to pay. After ten minutes as a guest we ask you to make a free account — it takes about ten seconds and the first three days are free.
Join any party as a guest and listen for ten minutes with no account at all. When those are up, a quick sign-up carries you on. The ten minutes are counted on our side, so closing the app and reopening it does not start them again.
Three days free while you try it, then from ₹11 a week, ₹39 a month or ₹449 a year. No card is asked for up front and nothing renews on its own during the trial. Full pricing.
It lives only for the party. When the party ends everything uploaded to it is deleted from the server, and a party ends automatically after three hours, or an hour after the last person leaves.
The website works on iPhone today, in Safari or Chrome. A native app is on the way.
Three days on us, no card asked for — then from ₹11 a week. Anyone can join with a code and listen for ten minutes before they need an account of their own.
