# SeaNav US vs Aqua Map Boating

The clearest difference is price: Aqua Map Boating at Free against SeaNav US's $19.99. Aqua Map Boating also leads on update cadence (weekly vs every 4 months) and rating (4.7 vs 4.3). On ads, in-app purchases, monetization model and chart position there is nothing between them.

Aqua Map Boating is free to download; SeaNav US costs $19.99 up front. SeaNav US sells 7 in-app purchases, starting at $7.49 per year and Aqua Map Boating sells 17 in-app purchases, starting at $4.99 per year. Whichever you choose, the download price is not the number that matters.

Aqua Map Boating holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Aqua Map Boating has 14K ratings behind it against 100, so its average is the more settled of the two.
