MeshLive

Calls, chats and livestreams over a Bluetooth mesh.
Every phone passes it on, so you reach further than Bluetooth alone.
No internet, no SIM, no account.

What it does

Calls Voice and video calls with people nearby End-to-end encrypted, phone to phone Missed calls, call back, block unknown callers Livestream Go live and share your camera with everyone around you Audio only, like a local radio that keeps playing with the screen off Phones in between pass your stream along

Contacts Add people by scanning each other's code Call them from Contacts whenever they're nearby Strangers only see a random name that changes every 15 minutes Your privacy No internet, SIM, account or server Your calls never touch the internet Delete everything from the phone in seconds

Works wherever there's no signal or Wi-Fi, like hikes, festivals, trips and basements. MeshLive is in beta: see which phones work, and don't rely on it where your safety depends on it.

How it works

Bluetooth on its own reaches about 10 to 30 metres. MeshLive turns every phone running it into a relay: your livestream or call hops from phone to phone, so the more people around you use MeshLive, the further you reach.

• Livestreams pass from phone to phone: everyone watching can also pass it on to the next people.
• Calls go straight to the other phone, or through phones in between when they are out of range (beta).
• Nothing touches the internet. Each hop adds a little delay and Bluetooth is slow, so video is small; audio-only streams reach the furthest.

Privacy

No accounts, no ads, no analytics, no servers. Calls and streams are encrypted, and your real name is only sent, encrypted, to the people you choose. What nearby phones can and can't see is explained in Privacy.
