# Marés vs Tide Charts

The clearest difference is review sentiment: Tide Charts at 69% against Marés's 19%. Tide Charts also leads on rating (4.8 vs 2.5) and update cadence (every 3 weeks vs every 4 months). Marés's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Tide Charts sells 1 one-off in-app purchase. Marés asks for nothing beyond the download.

Tide Charts holds the better App Store score, 4.8 against 2.5. That said, the two scores are not equally well evidenced: Tide Charts has 114K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 19% of Marés's written reviews are positive against 69% of Tide Charts's.

Marés ships an update every 4 months, Tide Charts every 3 weeks. The most recent releases landed on October 7, 2026 and October 22, 2026 respectively.
