Tangle

Tangle is an offline social network that lets you post, chat, comment and share photos without internet or mobile data. Using Bluetooth and local Wi-Fi, the app builds a peer-to-peer mesh so messages travel hop-by-hop between nearby phones, making it ideal for campuses, events, markets or areas with poor connectivity. You can use Tangle for real-time local conversation, emergency communication when networks fail, or simply to keep social interactions private and local — no central servers or sign-up required. It's a practical tool for anyone who wants instant, local sharing without relying on cellular data.
