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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
