About this app

Put the phones on the table, press play, and the whole room plays the same song at the same instant. SynkEngine turns the phones at a party into one sound system: no speakers, no cables, no account.

HOW IT WORKS
• One phone creates the party. Friends on the same Wi-Fi or hotspot join with one tap.
• The phones listen to the music in the room, line themselves up, then keep each other in step.
• Joining a party is always free.

WHAT YOU CAN PLAY
• Songs from your own phone
• YouTube, in YouTube's own player, on every phone
• SoundCloud, in SoundCloud's own player
• Share a song from the YouTube app to SynkEngine to add it to the party

AT THE PARTY
• Karaoke: sing into your phone and every other phone plays your voice, with the lyrics on screen if you like
• Everyone adds songs and votes; the most votes plays next
• The party master sees every phone and its connection, and can rest a phone the network can't keep up with
• "Which one?" makes a phone flash its name, so everyone knows whose phone is whose
• The master's volume buttons set the volume of the whole party
• In 11 languages: English, French, Spanish, Portuguese, Hindi, Chinese, Japanese, Korean, Thai, Vietnamese and Russian

PRIVATE BY DESIGN
No account, no ads of our own, no analytics. The phones talk to each other on your own network, and nothing about you or your music is sent to us. YouTube, SoundCloud and the lyrics come straight from those services.

GOOD TO KNOW
• Made for private parties. Playing music in public or in a business usually needs a licence from your local music rights society.
• Hosting a party is free for 40 minutes; after that, hosting needs a SynkEngine licence. Joining is always free.
• Music from a phone keeps the tightest sync and keeps playing with the screen off. Streamed songs need the app on screen.

SynkEngine is an independent app, not affiliated with YouTube, Google or SoundCloud.
One song on every phone at the same instant. Party sound, no speakers needed.

What’s new

6.61.6
• Bluetooth: the light's menu now asks before it changes a device between earphones and speaker (a speaker saved as earphones never timed itself).
• A Bluetooth device tuned by hand 5 times? SynkEngine offers to time it by its own sound.
• The master's desk points to a member's own Bluetooth check.
• 🏁 on an open deck says who can end the party; a master the host hands the deck to can end it.
• Fixes from the 31 Oct field test.
