SET THE ANCHOR Set your anchor location in real time as you drop it, or specify it later by entering distance and bearing. Advanced users can also input exact coordinates. DEFINE THE SAFE ZONE Define the allowed swing area as a simple circle around the anchor, or create a more precise zone by setting two different radii at specific angles. MONITOR MOVEMENT Stay on top of every movement with comprehensive real-time data. Review key metrics on the main screen or switch to the map view to see your boat's track — ideal for analyzing whether your anchor is holding or dragging. GET ALERTED WHEN IT MATTERS Monitor position, GPS signal strength, and battery level — and receive alerts the moment any of these fall outside your set thresholds. REMOTE ALERTS Leave your phone on board and stay informed from shore. Receive alarm notifications via Telegram or email. With Telegram, you can also request a live status update at any time.
