Verdict

The call

The clearest difference is in-app purchases: Happy Chicken at none against Chicken Evolution | Merge's 12. Happy Chicken also leads on review sentiment (100% vs 90%) and iOS requirement (10.0 vs 15.0). Chicken Evolution | Merge's advantage is update cadence (every 5 weeks vs every 10 months) and rating (4.8 vs 4.4). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Chicken Evolution | Merge holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Chicken Evolution | Merge has 3K ratings behind it against 106, so its average is the more settled of the two. Written reviews complicate that: 90% of Chicken Evolution | Merge's written reviews are positive against 100% of Happy Chicken's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Chicken Evolution | Merge ships an update every 5 weeks, Happy Chicken every 10 months. Both last shipped on October 29, 2026.
