Anchor Alarm - Anchor Watch

Anchor Alarm - Anchor Watch is an enhanced anchor monitoring app that uses customizable swing shapes rather than simple circles, so your warning area matches the real free space in every direction. It also features a loud alarm that wakes you if the anchor drags, even when the phone volume is low.

Version 2 overhauls the app with scalable map depictions of your vessel, swing-path tracking, optional anchor marking, GPS-filtered false alarms, and background alarms that run when the phone is locked. It also enables cross-device monitoring so you can watch from another device or location.
