# GPS Data vs Navigation Marine PRO

The clearest difference is price: GPS Data at Free against Navigation Marine PRO's $2.99. GPS Data also leads on rating (4.4 vs 2.0) and update cadence (fortnightly vs every 13 months). Navigation Marine PRO's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.

GPS Data is free to download; Navigation Marine PRO costs $2.99 up front. GPS Data sells 1 one-off in-app purchase. Navigation Marine PRO asks for nothing beyond the download.

GPS Data holds the better App Store score, 4.4 against 2.0. That said, the two scores are not equally well evidenced: GPS Data has 458 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 77% of GPS Data's written reviews are positive against 100% of Navigation Marine PRO's, so the app with the better star average is not the one people write more warmly about.

GPS Data ships an update fortnightly, Navigation Marine PRO every 13 months. The most recent releases landed on November 2, 2026 and October 24, 2026 respectively.
