# Aqua Map Boating vs Anchor Alert

The clearest difference is ratings volume: Aqua Map Boating at 14K against Anchor Alert's 12. Aqua Map Boating also leads on update cadence (weekly vs fortnightly) and chart position (#101 vs unranked). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Aqua Map Boating sells 17 in-app purchases, starting at $4.99 per year and Anchor Alert sells 3 in-app purchases, starting at $15.00 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 — 4.7 for Aqua Map Boating against 4.7 for Anchor Alert. That said, the two scores are not equally well evidenced: Aqua Map Boating has 14K ratings behind it against 12, so its average is the more settled of the two. Written reviews split almost evenly too, at 64% and 64% positive.

Aqua Map Boating ships an update weekly, Anchor Alert fortnightly. The most recent releases landed on October 20, 2026 and October 19, 2026 respectively.
