Explore freely — without live tracking.
Set your expected return time before you go. ABB alerts your emergency contacts only if you do not return on time.
How ABB works
1) Create your adventure
Name your adventure, choose your activity, set the location, and choose who gets notified.
2) Set your return time
Pick your date, time, and time zone. ABB keeps the clock so reminders and alerts line up with your real-world plans.
3) Start the beacon
When your expected return time passes, ABB sends you a reminder to check in. If you don't tap Mark Safe within 1 hour, your emergency contacts are alerted.
What makes ABB different
Privacy-first, no tracking
ABB never streams your live location or records GPS trails. It only uses the adventure details and contacts you choose to share, and only if you're overdue.
Built for real adventures
Your emergency contacts are only alerted if you don't return on time — not when you set off. Start your adventure knowing no one will be alarmed unnecessarily.
Works even if your phone dies
Once you start a beacon, ABB's server-side timer keeps running. Reminders and alerts can still go out even if your battery dies or you lose signal after you set your plans.
