# au vs circloO

The clearest difference is rating: circloO at 4.8 against au's 3.7. circloO also leads on review sentiment (89% vs 57%) and ratings volume (2.4K vs 36). au's advantage is ads (none vs shown) and iOS requirement (8.0 vs 10). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. au sells 3 one-off in-app purchases and circloO sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

circloO holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: circloO has 2.4K ratings behind it against 36, so its average is the more settled of the two. Written reviews point the same way: 57% of au's written reviews are positive against 89% of circloO's.

au ships an update every 5 weeks, circloO every 2 months. The most recent releases landed on October 5, 2026 and October 10, 2026 respectively.
