Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
IMIKI Ring holds the better App Store score, 3.0 against 2.8. That said, the two scores are not equally well evidenced: Circular Ring has 512 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 16% of Circular Ring's written reviews are positive against 0% of IMIKI Ring'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, IMIKI Ring every 20 months. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
