# Monster Evolution! vs Fish Eater.io

The clearest difference is update cadence: Monster Evolution! at weekly against Fish Eater.io's every 2 months. Monster Evolution! also leads on review sentiment (57% vs 28%) and iOS requirement (12.5 vs 15.6). Fish Eater.io's advantage is chart position (#47 vs unranked). On price, rating, ratings volume and ads there is nothing between them.

Both are free to download. Monster Evolution! sells 1 one-off in-app purchase and Fish Eater.io sells 11 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Fish Eater.io holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 33K and 59K respectively. Written reviews complicate that: 57% of Monster Evolution!'s written reviews are positive against 28% of Fish Eater.io's, so the app with the better star average is not the one people write more warmly about.

Monster Evolution! ships an update weekly, Fish Eater.io every 2 months. Both last shipped on September 30, 2026.
