# Bolts Off vs Wool Master 3D

The clearest difference is rating: Wool Master 3D at 4.9 against Bolts Off's 4.6. Wool Master 3D also leads on iOS requirement (13.0 vs 15.0). Bolts Off's advantage is ratings volume (14K vs 1.9K) and review sentiment (33% vs 22%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Bolts Off sells 18 one-off in-app purchases and Wool Master 3D sells 13 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Wool Master 3D holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Bolts Off has 14K ratings behind it against 1.9K, so its average is the more settled of the two. Written reviews complicate that: 33% of Bolts Off's written reviews are positive against 22% of Wool Master 3D's, so the app with the better star average is not the one people write more warmly about.

Bolts Off ships an update fortnightly, Wool Master 3D monthly. The most recent releases landed on October 30, 2026 and October 28, 2026 respectively.
