Three things you do. One thing we do.
Filing takes about ninety seconds and two required fields. Then you go. The only part that matters is remembering to end the trip — and if you forget, that’s the whole point.
Enter the required information
When you’ll be back, and who to tell. That’s it — everything else is optional and you can add it from the trailhead.
Nothing depends on signal. The timer started when you filed, and your people were told right then — this is the message they got:
Repeat a short pattern — or a short code at a keyboard — to end the trip. Short, so it can’t happen in your pocket on the drive home.
If you don’t end the trip, we start telling people. Slowly, and you first.
Most of the time it ends at the first step, because you’re fine and just running late. That’s the buffer doing its job.
The whole thing, in one table.
If you read nothing else on this site, read this.The late times are this example’s — yours are computed from your own trip and shown before you file. Your people are invited by email; you never type anyone’s phone number, and texts are theirs to switch on. When it matters, we use every channel they’ve given us. Someone who hasn’t accepted is never messaged and doesn’t count as cover; if nobody has accepted, we tell you before you leave.
