MeshLive / meshlive-android

# MeshLive
**Encrypted voice and video calls, live video and live audio between phones over a Bluetooth mesh. No internet needed.**
 Android 10 or newer · free · no account · How to install 
## What you can do
- **Call people nearby.** Voice or video, end-to-end encrypted, phone to phone.
- **Go live.** Share your camera with everyone around you, or go **audio only**, like a local radio that keeps playing with the screen off.
- **Reach further.** Phones in between pass calls and streams along, so you can reach people out of your own Bluetooth range.
- **Stay private.** No internet, SIM card, account or server. Strangers see a random name; your contacts recognise you.
Built for blackouts, disasters, censorship, remote places and crowded events. Free and open source (GPL-3.0).
## How it works
Your phone talks to nearby phones over Bluetooth, about 10 to 30 metres, never through the internet. A phone that receives a stream can pass it on, and the next phone can pass it on again: that chain is the mesh. Bluetooth is slow, so video is small and gets a little more delayed with each hop; audio-only streams reach further.

## Privacy
- The ID your phone broadcasts is random and changes every 15 minutes, so a listener cannot follow you.
- Calls hide both phones' identities from anyone listening in. A stranger sees a throwaway identity until you answer.
- Your name, if you set one, is never broadcast. A stream title is public, so everyone nearby can read it.
Limits, plainly: a live stream shows its source to everyone who watches; on Android 13 and older a phone that connects to yours can read its Bluetooth name; anyone whose call you accept learns who you are; there has been no independent security audit. Details: docs/PRIVACY.md.
## Install
1. On your phone, tap **Download MeshLive**.
2. Open the file. If Android asks, allow your browser to **install unknown apps**, then tap **Install**.
3. Open MeshLive and allow **Nearby devices**, **Camera** and **Microphone**.
Both people need MeshLive. To get updates automatically, add the project in Obtainium with the button above. With no internet, a friend can send you the app: in MeshLive, Settings, then **Share this app**. The app can also check for updates, but only if you say yes.
To check a download is genuine, see how to verify a release. Other install options, the file list, features and common questions are in the user guide.
## Status
MeshLive is in **beta**, tested on seven phones from Samsung, Xiaomi, ASUS and OPPO (Android 10 to 16) and with a first iPhone. Results vary by phone pair: see docs/DEVICES.md. Do not rely on it where your safety depends on it. An iPhone app is in development.
**Please report your phone.** The device report form takes two minutes; reports where everything worked help as much as failures.
## Build from source
You need JDK 21, the Android SDK with NDK `28.2.13676358` and CMake `3.22.1`, Perl and Python 3.11 or newer.
