# Idle Animal Evolution vs Snake Evolution

The clearest difference is ratings volume: Idle Animal Evolution at 5.1K against Snake Evolution's 367. Idle Animal Evolution also leads on update cadence (fortnightly vs every 5 weeks) and iOS requirement (10.0 vs 15.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Idle Animal Evolution sells 2 one-off in-app purchases and Snake Evolution sells 15 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Idle Animal Evolution against 4.8 for Snake Evolution. That said, the two scores are not equally well evidenced: Idle Animal Evolution has 5.1K ratings behind it against 367, so its average is the more settled of the two. Written reviews are what separate them: 69% of Idle Animal Evolution's written reviews are positive against 71% of Snake Evolution's.

Idle Animal Evolution ships an update fortnightly, Snake Evolution every 5 weeks. The most recent releases landed on October 30, 2026 and October 27, 2026 respectively.
