# Cow Evolution vs Vampire Evolution

The clearest difference is ratings volume: Cow Evolution at 23K against Vampire Evolution's 126. Cow Evolution also leads on update cadence (every 10 days vs every 6 weeks). Vampire Evolution's advantage is review sentiment (100% vs 80%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Cow Evolution sells 12 one-off in-app purchases and Vampire Evolution sells 13 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 Vampire Evolution. That said, the two scores are not equally well evidenced: Cow Evolution has 23K ratings behind it against 126, 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 100% of Vampire Evolution's.

Cow Evolution ships an update every 10 days, Vampire Evolution every 6 weeks. The most recent releases landed on September 25, 2026 and September 21, 2026 respectively.
