Anchor Alarm: Boat Watch

Set the anchor, choose a safe zone, and keep a clear eye on your boat’s movement—even when a map is unavailable.

ANCHOR WATCH, MADE CLEAR

Anchor Alarm helps you monitor a small boat or yacht while anchored. Mark the anchor position, set a safe zone, and follow your boat’s movement on a focused marine radar.

BUILT FOR REAL ANCHORAGES

• Clear drift distance, GPS accuracy, safe-zone status, and movement trail • Circle, ellipse, and corridor zones for different anchoring situations • A practical radar view that remains useful when a map is unavailable • GPS filtering designed to reduce the effect of noisy location samples • A sound and notification check before you settle in

ANCHOR ALARM PRO

• Background monitoring while the screen is locked • Local alert notification when confirmed movement crosses the safe boundary • Anchor-session history with the recorded swing track • A calm night interface for a dark cabin

Privacy comes first: no account, no advertising, and no developer-operated location server. Location and trip history stay on your iPhone.

Important: GPS accuracy, iOS background execution, notification delivery, device power, Focus, and Silent Mode can affect alerts. Force-quitting the app or turning off the device stops monitoring. Anchor Alarm is an aid and does not replace a proper anchor watch, seamanship, or certified navigation equipment.
