# SeaNav vs GPS2IP Lite

The clearest difference is rating: SeaNav at 4.4 against GPS2IP Lite's 3.7. SeaNav also leads on ratings volume (251 vs 3) and update cadence (monthly vs every 3 months). GPS2IP Lite's advantage is in-app purchases (none vs 18). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. SeaNav sells 18 in-app purchases, starting at $4.99 per year. GPS2IP Lite asks for nothing beyond the download.

SeaNav holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: SeaNav has 251 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 55% of SeaNav's written reviews are positive against 60% of GPS2IP Lite's, so the app with the better star average is not the one people write more warmly about.

SeaNav ships an update monthly, GPS2IP Lite every 3 months. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
