# CDO2 vs Cat Wars

The clearest difference is rating: CDO2 at 4.7 against Cat Wars's 3.3. CDO2 also leads on update cadence (fortnightly vs every 2 months) and ratings volume (35 vs 3). Cat Wars's advantage is ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. CDO2 sells 15 one-off in-app purchases and Cat Wars sells 17 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

CDO2 holds the better App Store score, 4.7 against 3.3. That said, the two scores are not equally well evidenced: CDO2 has 35 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 80% of CDO2's written reviews are positive against 67% of Cat Wars's.

CDO2 ships an update fortnightly, Cat Wars every 2 months. The most recent releases landed on September 21, 2026 and September 10, 2026 respectively.
