Anchor Watch (free) is a practical utility application designed specifically for boaters to monitor their anchored position. Users can easily activate the app after dropping anchor, requiring only the bearing and distance to the anchor, without the need for exact coordinates. Key features include background task support, allowing alarms to function while using other apps, and a user-friendly drag-and-drop interface for setting and adjusting alarms. Additionally, the app supports advanced drift radius settings, making it ideal for crowded anchorages or when mooring near buoys.

This application operates fully offline, eliminating the need for an internet connection, while also providing optional access to OpenSeaMap data for enhanced navigation. Users can configure measurement units to suit their preferences, and the map can be rotated according to the device's compass. Permissions include fine GPS location tracking, wake lock for alarms, and access to external storage for offline map capabilities.
