# Cow Evolution vs Save the Koala

The clearest difference is rating: Cow Evolution at 4.7 against Save the Koala's 3.5. Cow Evolution also leads on ratings volume (24K vs 2) and update cadence (every 10 days vs monthly). Save the Koala's advantage is ads (none vs shown) and review sentiment (91% vs 80%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Cow Evolution sells 12 one-off in-app purchases and Save the Koala sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Cow Evolution holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: Cow Evolution has 24K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 80% of Cow Evolution's written reviews are positive against 91% of Save the Koala's, so the app with the better star average is not the one people write more warmly about.

Cow Evolution ships an update every 10 days, Save the Koala monthly. The most recent releases landed on October 20, 2026 and October 13, 2026 respectively.
