# Cow Evolution vs Robot Evolution

The clearest difference is update cadence: Cow Evolution at every 10 days against Robot Evolution's every 6 weeks. Cow Evolution also leads on ratings volume (23K vs 729). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Cow Evolution sells 12 one-off in-app purchases and Robot Evolution sells 12 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 Cow Evolution against 4.8 for Robot Evolution. That said, the two scores are not equally well evidenced: Cow Evolution has 23K ratings behind it against 729, so its average is the more settled of the two. Written reviews are what separate them: 80% of Cow Evolution's written reviews are positive against 86% of Robot Evolution's.

Cow Evolution ships an update every 10 days, Robot Evolution every 6 weeks. The most recent releases landed on October 1, 2026 and September 15, 2026 respectively.
