More than just a music player
Phasor brings people and music together, with everything a room needs. Open one around whatever you are listening to, at any time.
- One phone hosts and the rest receive. The host decides who gets in
- Play, pause and seek for everyone, with a queue, shuffle and repeat
- Set the room’s volume or each phone’s own
- Tap Talk and everyone hears you, with the music quieter underneath
- If you allow it, the music carries on with the app closed
Phones in these pictures are illustrations drawn from Phasor’s own design, with example songs. Screens in the gallery below are captures.
How It Works

Nobody signs up, and nobody hunts through settings.

Connect Nearby Devices
The others scan the code on your screen.


Play Together
Every phone plays the same moment.


One listening experience. Multiple devices.
Press play in a room without Phasor and every phone starts a little apart. With Phasor, they play as one. Here is the same beat on four phones, both ways.
A demonstration made in your browser. The gaps are chosen so you can hear them.
Four copies of one beat, slightly apart. The room hears a blur.
More than your music library.
Device Audio shares what another app on your phone is playing with everyone in the room. You keep using that app as usual.
Some apps do not allow their sound to be shared, and the room stays quiet for them. Android also stops sharing when the screen locks.
Live Listening
A service in every language.
One phone speaks to everyone’s phones and earbuds, for services, talks, classes and events. People hear it clearly wherever they sit.
- Main
- Yoruba
- Igbo
- Hausa
- Pidgin
- or any name you type
- Real interpreters, on their own phonesAn interpreter puts in earbuds, hears Main and taps Start interpreting. Only people who chose that language hear them.
- Up to 250 phones, no equipment to hireBig rooms run on the venue’s Wi-Fi. Connect the sound desk with a USB audio adapter or a headset cable.



Good music is even better together.
Road trips, kitchens, rooftops and quiet evenings. If the people around you have phones, you already have the speakers.
- Works offline
- No accounts
- Encrypted
- Free, with no ads

Questions
Something not working?Do I need the internet?
No. The phones only need to be on the same Wi-Fi or one phone’s hotspot. With no Wi-Fi at all, the host’s phone can make a network just for the room.
How many phones can join?
A music room takes up to 32 phones and a live listening room up to 250. Rooms that size need a real Wi-Fi router: a network a phone makes itself takes only a few phones.
Is Phasor on iPhone?
Not yet. Phasor is on Android first, and an iPhone version is planned.
Can it play what is in my streaming app?
On Android, Device Audio shares what another app is playing. Some apps do not allow their sound to be shared, and the room stays quiet for them. Android also stops sharing when the screen locks.
Will Bluetooth speakers stay in sync?
Phone speakers and wired headphones stay in sync best. Bluetooth adds its own delay, so a phone playing through a Bluetooth speaker can sound a little behind the others.
Who does the translating in live listening?
People do. Each language is a real interpreter on their own phone, so it works offline and in any language you can find an interpreter for.
Does anything leave my phone?
Only to the other phones in your room, encrypted. Nothing about you reaches us, because there is no account or server for it to reach.
What does it cost?
Phasor is free, with no ads and nothing locked away. You can leave a tip from Settings if you want to. It unlocks nothing.
