# Global tide vs Tide Charts

The clearest difference is rating: Tide Charts at 4.8 against Global tide's 3.9. Tide Charts also leads on ratings volume (115K vs 32) and chart position (#33 vs unranked). Global tide's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.1). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. Global tide sells 4 one-off in-app purchases and Tide Charts sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Tide Charts holds the better App Store score, 4.8 against 3.9. That said, the two scores are not equally well evidenced: Tide Charts has 115K ratings behind it against 32, so its average is the more settled of the two. Written reviews complicate that: 74% of Global tide's written reviews are positive against 69% of Tide Charts's, so the app with the better star average is not the one people write more warmly about.

Global tide ships an update monthly, Tide Charts every 3 weeks. Both last shipped on November 1, 2026.
