# Ocean Fish Evolution vs Idle Aquaria

The clearest difference is rating: Ocean Fish Evolution at 3.8 against Idle Aquaria's 3.0. Ocean Fish Evolution also leads on ratings volume (2.1K vs 10) and iOS requirement (13.0 vs 16.0). Idle Aquaria's advantage is update cadence (every 5 days vs every 2 months). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Ocean Fish Evolution sells 14 in-app purchases, starting at $7.99 per 7 days and Idle Aquaria sells 12 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Ocean Fish Evolution holds the better App Store score, 3.8 against 3.0. That said, the two scores are not equally well evidenced: Ocean Fish Evolution has 2.1K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 12% of Ocean Fish Evolution's written reviews are positive against 16% of Idle Aquaria's, so the app with the better star average is not the one people write more warmly about.

Ocean Fish Evolution ships an update every 2 months, Idle Aquaria every 5 days. The most recent releases landed on September 25, 2026 and September 20, 2026 respectively.
