## Description

Sleep easy at anchor. Anchor Alarm Pro watches your GPS position and sounds a loud alarm the moment your boat drags - even through the silent switch and overnight.

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.
