# Armillary Sphere vs Tinkercad

The clearest difference is rating: Tinkercad at 4.6 against Armillary Sphere's 4.0. Tinkercad also leads on ratings volume (20K vs 6). Armillary Sphere's advantage is review sentiment (86% vs 59%) and device support (3 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Tinkercad holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Tinkercad has 20K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 86% of Armillary Sphere's written reviews are positive against 59% of Tinkercad's, so the app with the better star average is not the one people write more warmly about.

Armillary Sphere ships an update every 5 months, Tinkercad every 4 months. The most recent releases landed on October 16, 2026 and October 22, 2026 respectively.
