# SeaNav vs SailSpeed

The clearest difference is review sentiment: SailSpeed at 100% against SeaNav's 55%. SeaNav's advantage is rating (4.4 vs 3.8) and update cadence (every 3 weeks vs every 14 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. SeaNav sells 18 in-app purchases, starting at $4.99 per year and SailSpeed sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

SeaNav holds the better App Store score, 4.4 against 3.8. That said, the two scores are not equally well evidenced: SeaNav has 247 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 55% of SeaNav's written reviews are positive against 100% of SailSpeed's, so the app with the better star average is not the one people write more warmly about.

SeaNav ships an update every 3 weeks, SailSpeed every 14 months. The most recent releases landed on September 22, 2026 and September 25, 2026 respectively.
