Permission in writing, and a warning before you cross the line
Turn a verbal yes into a signed PDF, keep each landowner's permission with its expiry date and boundary in one place, and let your phone warn you before you cross the line you agreed to.
Android only.
Turn a verbal yes into a signed PDF
A permission letter with a satellite map of exactly where you'll detect, signed by the landowner on your screen, stored encrypted, with a calendar reminder before it expires.
- A4 request letter + thank-you letter, generated in-app
- On-screen signature, drawn by the landowner
- Encrypted at rest; screenshots blocked
- Expiry reminders 14 days ahead
Alerts you before you cross the boundary
Draw the boundary you agreed with the landowner. The phone checks your position every 2 seconds and escalates from a vibration at 15 meters to a full alarm at the line, even through Do Not Disturb.
- 4 escalating zones: 15 m, 8 m, 3 m, crossed
- Vibration tuned to reach a pocket through field clothing
- Alarm punches through Do Not Disturb
- Any measured polygon becomes a Guard in one tap
