Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
