HOP: Offline Messenger

HOP is a free messenger that works with no internet and no cell signal. Messages hop from phone to phone and travel further than any single device can reach. On iPhone, HOP connects over a shared Wi‑Fi network (no internet needed, e.g. a hotspot), and iPhones near each other can also connect directly over Apple’s peer-to-peer Wi‑Fi, with no network at all. The internet is optional. A message can pass through many phones on the way, and with no route it waits and sends itself later. iOS pauses connections in the background, so the mesh works while HOP is open. WHERE IT HELPS • Concerts and festivals — when thousands of phones jam the network • Matches and stadiums — find your group after half-time • Planes — in airplane mode, turn Wi‑Fi back on and text fellow passengers • Mountains, trails, sailing — valleys with no coverage • Outages, storms, blackouts • Camps and school trips…
