Verdict
The clearest difference is ratings volume: Circadia at 11K against Dotsu's 343. Circadia also leads on review sentiment (85% vs 69%) and iOS requirement (8.0 vs 15.0). On price, rating, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Circadia sells 1 one-off in-app purchase and Dotsu sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.6 for Circadia against 4.6 for Dotsu. That said, the two scores are not equally well evidenced: Circadia has 11K ratings behind it against 343, so its average is the more settled of the two. Written reviews are what separate them: 85% of Circadia's written reviews are positive against 69% of Dotsu's.
Circadia ships an update every 3 weeks, Dotsu fortnightly. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
