Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Circular Ring holds the better App Store score, 2.8 against 2.1. That said, the two scores are not equally well evidenced: Circular Ring has 493 ratings behind it against 36, so its average is the more settled of the two. Written reviews complicate that: 16% of Circular Ring's written reviews are positive against 25% of Silo Kitchen's, so the app with the better star average is not the one people write more warmly about.
Circular Ring ships an update every 2 weeks, Silo Kitchen every 6 weeks. The most recent releases landed on September 22, 2026 and September 23, 2026 respectively.
