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.

Verdict
The clearest difference is in-app purchases: SailBot at none against Anchor Pro's 1. SailBot also leads on review sentiment (100% vs 79%) and iOS requirement (11.0 vs 17.2). Anchor Pro's advantage is ratings volume (3.5K vs 5) and update cadence (every 2 months vs every 8 months). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Anchor Pro sells 1 in-app purchase, starting at $6.99 per year. SailBot asks for nothing beyond the download.
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 5, so its average is the more settled of the two. Written reviews complicate that: 100% of SailBot'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.
SailBot ships an update every 8 months, Anchor Pro every 2 months. The most recent releases landed on September 29, 2026 and October 12, 2026 respectively.
