BuddySOS

BuddySOS is a group safety app that puts your crew on a live shared map and lets you send a one-tap SOS with your real-time location. Set safe zones for instant entry and exit alerts, and see everyone in your group at a glance. It also texts your emergency contacts, who don't need the app installed.

BuddySOS keeps your data private with no location history and nothing sold. It's free on iOS and Android, with optional upgrades for more groups and zones.
