Find your people, anywhere. GroupIn helps you and your friends find each other in real time — at festivals, on a trip, around the city, on a hike. Open the app, create a group, share a code, and everyone sees the same live map. Built for the moments that matter • Stop typing "where are you?" — see everyone on one live map. • Walk toward a friend with the precision compass. • On iPhone 11 and later, GroupIn uses Ultra Wideband for AirTag-style direction finding. Works when nothing else does Most apps stop the moment the signal drops. GroupIn keeps working over Bluetooth and direct device-to-device — so you can still find each other in the crowd, the venue, the canyon. When you're back online, it picks up where it left off. Joining is one tap No account. No email. No password. The group creator shares a code or QR — everyone else taps it. That's it. End-to-end encrypted Your group's location, chat, and profile photos are encrypted on your phone before they're sent anywhere. Even Apple and our servers cannot read your data. The invite code is the key — only people you share it with can join your group. Designed around privacy • No sign-up, no email, no tracking. • Groups expire automatically — set your own duration. • Leaving a group removes you from everyone's map instantly. • Owners can remove members or delete the whole group at any time. Great for • Festivals and concerts • Group trips, road trips, and hikes • Friends meeting up across a city • Family on vacation • Conferences and conventions • Block parties and small events GroupIn is built by a small independent team. We don't sell ads, we don't sell your data, and there's no feed. The app does one thing — help you find each other — and it does it well.
