Dolphin Evolution and Merge Zoo both sit at 4.7 stars, but that hides the real split: 93% of Dolphin Evolution's written reviews are positive against 55% of Merge Zoo's.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Dolphin Evolution sells 16 one-off in-app purchases and Merge Zoo sells 13 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Merge Zoo holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Dolphin Evolution has 807 ratings behind it against 70, so its average is the more settled of the two. Written reviews complicate that: 93% of Dolphin Evolution's written reviews are positive against 55% of Merge Zoo's, so the app with the better star average is not the one people write more warmly about.
Dolphin Evolution ships an update every 6 weeks, Merge Zoo every 4 weeks. The most recent releases landed on October 18, 2026 and October 10, 2026 respectively.
