Tangle

Tangle is an offline social network that lets you connect with people nearby without internet or mobile data. Using Bluetooth and local Wi-Fi, the app creates a mesh between phones so you can post, comment, chat and share photos in real time within a crowd or neighbourhood. Because content travels hop-by-hop through nearby devices there are no central servers and no account sign-up is required. If you need quick, private local communication at events, on campus or during outages, Tangle makes it easy to stay connected to the people right around you.

⭐ Peer-to-peer chat — message other local users directly without a central server.

⭐ Image sharing — photos are optimized for fast wireless transfer between devices.

⭐ Mesh relay — posts propagate hop-by-hop through nearby phones to extend reach.
