# Anchor Pro vs SailboatData

The clearest difference is update cadence: SailboatData at every 4 weeks against Anchor Pro's every 2 months. SailboatData also leads on review sentiment (89% vs 79%) and iOS requirement (15.5 vs 17.2). Anchor Pro's advantage is ratings volume (3.5K vs 293). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Anchor Pro sells 1 in-app purchase, starting at $6.99 per year and SailboatData sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Anchor Pro against 4.8 for SailboatData. That said, the two scores are not equally well evidenced: Anchor Pro has 3.5K ratings behind it against 293, so its average is the more settled of the two. Written reviews are what separate them: 79% of Anchor Pro's written reviews are positive against 89% of SailboatData's.

Anchor Pro ships an update every 2 months, SailboatData every 4 weeks. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
