# circloO vs AI Simulator

The clearest difference is update cadence: AI Simulator at weekly against circloO's every 2 months. AI Simulator also leads on review sentiment (100% vs 89%). circloO's advantage is ratings volume (2.5K vs 8) and iOS requirement (10 vs 13.4). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. circloO sells 1 one-off in-app purchase and AI Simulator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for circloO against 4.8 for AI Simulator. That said, the two scores are not equally well evidenced: circloO has 2.5K ratings behind it against 8, so its average is the more settled of the two. Written reviews are what separate them: 89% of circloO's written reviews are positive against 100% of AI Simulator's.
