For each level, the animated pieces draw increasingly complex patterns. The challenge is to be attentive to image juxtapositions in order to stop each circles movement at the right moment. Now available on the App Store with retina graphics! "Beautiful. Engaging.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
OKO costs $3.99 and The Guides Compendium $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
The Guides Compendium holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: The Guides Compendium has 18 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 71% of OKO's written reviews are positive against 70% of The Guides Compendium's, so the app with the better star average is not the one people write more warmly about.
OKO ships an update every 44 months, The Guides Compendium every 25 months. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
