# Fish Eater.io vs Monster Trainer

The clearest difference is rating: Fish Eater.io at 4.8 against Monster Trainer's 4.4. Fish Eater.io also leads on ratings volume (59K vs 3.4K) and chart position (#47 vs unranked). Monster Trainer's advantage is review sentiment (54% vs 28%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Fish Eater.io sells 11 in-app purchases, starting at $2.99 per 7 days and Monster Trainer sells 19 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Fish Eater.io holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Fish Eater.io has 59K ratings behind it against 3.4K, so its average is the more settled of the two. Written reviews complicate that: 28% of Fish Eater.io's written reviews are positive against 54% of Monster Trainer's, so the app with the better star average is not the one people write more warmly about.

Fish Eater.io ships an update every 2 months, Monster Trainer every 4 months. The most recent releases landed on September 30, 2026 and September 29, 2026 respectively.
