Small Group Tracker
Read full descriptionHide full description
Small Group Tracker shares live location with a small group — up to 6 people — during a walk, hike, festival, or day out. One person creates a group and shares a QR code; everyone else scans it to join. From there, everyone's position, messages, and points of interest travel directly between phones over an encrypted peer-to-peer connection. Nothing is stored on a server, and no account or sign-up is required. MAIN FEATURES Live group map Everyone in the group appears as a coloured pin on the map, updating automatically as people move. Quick join by QR code No usernames or passwords. Scan a code, enter your name, and you're on the map. Group messaging Send a message to everyone in the group instantly, with a notification sound. Panic button One tap alerts every group member with an alarm and your last known location, for genuine emergencies. Points of interest Drop a shared pin — a meeting point, parking spot, or landmark — visible to the whole group, and export it for reuse. Automatic expiry Every group has an expiry time. When it passes, or the Coordinator ends the event, all group data is deleted. PRIVACY BY DESIGN Your location never touches our servers — it travels directly between your group's phones.
