# marée.info vs Meduseo

The clearest difference is in-app purchases: Meduseo at none against marée.info's 3. Meduseo also leads on rating (5.0 vs 4.6) and update cadence (every 2 weeks vs monthly). marée.info's advantage is ads (none vs shown) and ratings volume (28 vs 3). On price, review sentiment and device support there is nothing between them.

Both are free to download. marée.info sells 3 one-off in-app purchases. Meduseo asks for nothing beyond the download.

Meduseo holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: marée.info has 28 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 89% of marée.info's written reviews are positive against 81% of Meduseo's, so the app with the better star average is not the one people write more warmly about.

marée.info ships an update monthly, Meduseo every 2 weeks. The most recent releases landed on October 16, 2026 and October 9, 2026 respectively.
