# Circadia vs Rytmos

The clearest difference is rating: Circadia at 4.6 against Rytmos's 3.6. Circadia also leads on review sentiment (85% vs 48%) and ratings volume (11K vs 62). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Circadia holds the better App Store score, 4.6 against 3.6. That said, the two scores are not equally well evidenced: Circadia has 11K ratings behind it against 62, so its average is the more settled of the two. Written reviews point the same way: 85% of Circadia's written reviews are positive against 48% of Rytmos's.

Circadia ships an update every 3 weeks, Rytmos every 2 months. The most recent releases landed on October 16, 2026 and October 15, 2026 respectively.
