CLUSTER MESSAGING-NEARBY-OFFLINE · 16 ENTRIES · EARLIEST ENTRY 2026-05-05

Offline Bluetooth messaging apps

This cluster consists of offline-first social messaging and networking apps that use Bluetooth or direct device-to-device connections to exchange messages and content without internet or cellular infrastructure. Only three dated entries exist before the index start, so the cluster's dated history is too thin to read a shape from. Traction is led by offgrid with 1 star, while offGrd and AirChat each have 0 stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
