# Geometry!! vs Circle & Sphere

The clearest difference is rating: Geometry!! at 4.5 against Circle & Sphere's 4.0. Geometry!! also leads on ratings volume (56 vs 4). Circle & Sphere's advantage is ads (none vs shown) and review sentiment (100% vs 67%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Geometry!! sells 2 in-app purchases, starting at $0.99 per year and Circle & Sphere sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Geometry!! holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Geometry!! has 56 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 67% of Geometry!!'s written reviews are positive against 100% of Circle & Sphere's, so the app with the better star average is not the one people write more warmly about.

Geometry!! ships an update every 7 months, Circle & Sphere every 3 weeks. The most recent releases landed on September 28, 2026 and September 19, 2026 respectively.
