About this app
Chat with everyone around you when there's no signal. Messages hop from phone to phone.
Hopline is an Android app for treks, camps, festivals, fairs, rallies, power cuts — anywhere people with phones have no mobile signal and no WiFi. Phones link to each other directly over Bluetooth / WiFi, and every phone passes messages along for the others, so a message can travel down a line of hikers or across a packed ground, far beyond the range of any single phone. It works the same for five friends or a crowd — the protocol automatically sheds overhead as the group grows (see Built for a crowd below).
No internet. No mobile signal. No account. No server. No hotspot to set up.
