Description
Anchor Alarm Pro turns your iPhone into a dependable anchor watch. Drop your anchor, set a safe radius, and the app sounds a loud, escalating alarm the instant your boat drags outside the zone, so you can actually sleep at anchor.
KEEPS YOU SAFE OVERNIGHT
Loud alarm that overrides the silent switch and rings even when the phone is asleep
Soft pre-alert first, then a full alarm if you don't respond
Smart drag detection that ignores normal swinging and won't false-alarm when you motor up to retrieve the anchor
FLEXIBLE ANCHOR ZONES
Simple circular safe zone around the anchor
Sector zones for swing on a single tide line
Bow/stern corridor for Mediterranean and stern-to mooring: point your bow and set how far the boat may move
ACCURATE POSITION, YOUR WAY
Built-in iPhone GPS
External Bluetooth GPS receiver for better accuracy
NMEA 0183 over TCP/UDP from your chartplotter, or Signal K from your boat network
Auto-selects the most accurate connected source
WATCH FROM YOUR PHONE OR FROM SHORE
Share a short code to link a second device, no account, no login
One phone stays on the boat; another monitors remotely and gets the same drag alarm via push notification, even backgrounded
Live boat position, track history, and battery status of the boat's device
BUILT FOR REAL CRUISING
Live map with your track, swing circle, and OpenSeaMap-style detail
Battery-conscious: eases off GPS while holding, sharpens up near the edge or while dragging
Scrub back through your night's track to see exactly where you sat
Anchor Alarm Pro is made by sailors, for sailors. Set it once and trust it.
