Chat with friends.
No internet required.

Yes. GoFiChat talks phone to phone over Bluetooth Low Energy, and over local Wi-Fi when you share a network or hotspot. Airplane mode is fine as long as Bluetooth is switched back on.

Install GoFiChat while you still have internet, and ask the people you're travelling with to do the same. Downloading the app needs a connection. Using it doesn't.

Bluetooth usually reaches 10–30 metres depending on walls, bodies and the phones involved. The phones in a room link through one of them, so stay reasonably close together. If someone drifts out of range, their seat is kept for three minutes and they're back in when they return, and GoFiChat warns them first when they're getting far away.

Yes. Both connect over standard Bluetooth Low Energy, so mixed groups work, and they play the same games together. An Android phone can't find a room on an iPhone that's in the background, though, so if the room is on an iPhone, keep GoFiChat open on it while people join or come back.

English, Spanish, Portuguese (Brazil), Hindi and Indonesian. Each phone uses its own language, so a mixed group can play together: in Odd One Out each phone shows the secret word in its own language, and Draw and Guess accepts a right guess in any of them.

People who have been in the room before get back in by themselves, and friends you invite come straight in. Anyone who scans your QR code or opens your room link also comes straight in, so share those only with people you want there. Someone who types the 6-digit code waits until you tap Let in, and both phones show the same pictures to check first. A room shows on the Nearby list of people who haven't been in it only if an adult turns on Show on Nearby, then only for 10 minutes, and only on phones whose age check says adult. If someone causes trouble, block them and you won't see anything they send. On the phone the room runs through, blocking also removes them and changes the room's keys, QR code and link, so they can't come back without being let in again. Block and Report also tell us, with their last 10 messages, and we remove people who break the rules from GoFiChat.

Yes. Messages are end-to-end encrypted with keys made on the phones for that room only (X25519 key exchange and ChaCha20-Poly1305). There are no accounts, and messages never go through a server, so there's nothing for us to see or store, apart from the messages in a report someone sends us. Scanning the QR code also checks the room's key, so nobody can pretend to be your room. When someone types the code instead, the person letting them in checks both phones show the same pictures first.

Each phone keeps the last 50 rooms it was in, with up to 2,000 messages of each one's chat, so you can scroll back and open a room again. It all stays on that phone and isn't backed up to iCloud or Google. You can forget a room, delete the chats, or turn chat history off in Settings.

Yes. Tap Practice with GoFi Bot on the home screen. The bot chats back and plays 15 of the 17 games at Easier, Normal or Harder; Odd One Out and Draw and Guess need friends. Gumblox, Mini Golf, Bowling, Darts, Memory and Quiz also have Play solo.

A chat uses very little, because Bluetooth Low Energy is built to run on low power. Live games like air hockey use more because the screen and radio stay busy.

The room carries on. Another phone in it takes over by itself and everyone stays in. When the last person leaves, the room is still on everyone's phone, ready to open again.

No. GoFiChat is free, with no ads and no in-app purchases.
