PlaneChat: Offline Messaging

No signal, no problem. Chat with the people around you over Bluetooth and Wi-Fi, even the plane's Wi-Fi without buying internet. End-to-end encrypted, no servers.

PlaneChat lets you chat with people nearby when there's no internet: on a flight, at a festival, on a hike, or anywhere the signal drops.

Phones talk to each other directly over Bluetooth and peer-to-peer Wi-Fi. When the person you're writing to is out of range, other phones running PlaneChat pass the message along, so a busy place carries it much further than one phone could.

PRIVATE BY DESIGN • No account, no phone number, no email. • No servers and no tracking: your messages never touch the internet. • Private chats are end-to-end encrypted. Phones that relay them can't read them or see who they're for. • Conversations live in memory and disappear when you close the app.

MADE FOR PEOPLE AROUND YOU • See who's nearby as bubbles and ask "Wanna chat?". Nobody can message you until you accept. • Get a notification when someone asks to chat or messages you, while PlaneChat runs in the background. • Join the public room, or make a private room with a code only your group knows. • Add friends so they can reach you straight away, or switch to Friends only and stay invisible to everyone else. • Edit a message after sending it; everyone can see what changed. • Check you're talking to the right person by comparing a short code in person.

SAFE BY DEFAULT • Block or report anyone with a long press. • Offensive words are hidden automatically.

Everyone you want to reach needs PlaneChat open or in the background on their iPhone, with Bluetooth and Wi-Fi switched on. In airplane mode you can turn both back on from Control Center and keep chatting.
