# OpenSeaMap vs Navily

The clearest difference is review sentiment: Navily at 94% against OpenSeaMap's 38%. Navily also leads on rating (4.8 vs 1.0) and ratings volume (832 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. OpenSeaMap sells 1 one-off in-app purchase and Navily sells 4 in-app purchases, starting at $9.49 per year. Whichever you choose, the download price is not the number that matters.

Navily holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: Navily has 832 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 38% of OpenSeaMap's written reviews are positive against 94% of Navily's.

OpenSeaMap ships an update every 2 months, Navily fortnightly. The most recent releases landed on October 12, 2026 and October 15, 2026 respectively.
