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.

Verdict

The call

The clearest difference is review sentiment: Anchor Pro at 79% against Epoch Li's 29%. Anchor Pro also leads on rating (4.8 vs 2.6) and ratings volume (3.5K vs 68). Epoch Li's advantage is in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 2 months). On price, ads and device support there is nothing between them.
