Anchor Alarm – Boat Monitor

Anchor Alarm keeps watch while you relax.
The app alerts you instantly if your boat drifts outside the anchoring area you define — helping you stay safe and sleep better at anchor.

Key Features

Drift Notifications

Get instant alerts when your boat moves beyond your safe zone.

Custom Polygon Area

Define an accurate polygon-shaped anchoring zone based on the specific layout of the anchorage. Perfect for complex shorelines, crowded bays, or irregular holding areas.

Share Settings Between Devices

Transfer your anchor position and defined area to another device using a QR code.
(Requires internet connection only for sharing — not for normal operation.)

Works Fully Offline

Anchor monitoring works without internet access. Ideal for remote anchorages.

No Registration Needed

No account, no cloud storage — your data stays on your device.
