# PRO CHARTS vs Seapilot

The clearest difference is rating: PRO CHARTS at 4.5 against Seapilot's 2.8. PRO CHARTS also leads on ratings volume (8.5K vs 16) and chart position (#188 vs unranked). Seapilot's advantage is review sentiment (38% vs 17%) and iOS requirement (9.3 vs 15.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. PRO CHARTS sells 4 in-app purchases, starting at $2.99 per month and Seapilot sells 18 in-app purchases, starting at $8.99 per year. Whichever you choose, the download price is not the number that matters.

PRO CHARTS holds the better App Store score, 4.5 against 2.8. That said, the two scores are not equally well evidenced: PRO CHARTS has 8.5K ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 17% of PRO CHARTS's written reviews are positive against 38% of Seapilot's, so the app with the better star average is not the one people write more warmly about.

PRO CHARTS ships an update every 2 months, Seapilot every 3 months. Both last shipped on October 24, 2026.
