# Marinus vs Seagull Training

The clearest difference is review sentiment: Marinus at 65% against Seagull Training's 28%. Marinus also leads on update cadence (every 5 weeks vs every 3 months) and ratings volume (215 vs 55). Seagull Training'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. Marinus sells 1 in-app purchase, starting at $8.99 per year. Seagull Training asks for nothing beyond the download.

Seagull Training holds the better App Store score, 4.8 against 4.4. Both are backed by a comparable volume of ratings — 215 and 55 respectively. Written reviews complicate that: 65% of Marinus's written reviews are positive against 28% of Seagull Training's, so the app with the better star average is not the one people write more warmly about.

Marinus ships an update every 5 weeks, Seagull Training every 3 months. Both last shipped on October 24, 2026.
