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 in-app purchases: Freedive at none against Anchor Pro's 1. Freedive also leads on review sentiment (94% vs 79%) and iOS requirement (8.0 vs 17.2). Anchor Pro's advantage is ratings volume (3.5K vs 14) and rating (4.8 vs 4.6). On price, update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Anchor Pro holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Anchor Pro has 3.5K ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 94% of Freedive's written reviews are positive against 79% of Anchor Pro's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Freedive ships an update every 6 weeks, Anchor Pro every 2 months. The most recent releases landed on August 19, 2026 and September 23, 2026 respectively.
