# Spin Pin AA vs Muscle Boy

The clearest difference is rating: Muscle Boy at 4.4 against Spin Pin AA's 3.9. Muscle Boy also leads on ratings volume (4.3K vs 25). Spin Pin AA's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, update cadence, in-app purchases and device support there is nothing between them.

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

Muscle Boy holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: Muscle Boy has 4.3K ratings behind it against 25, so its average is the more settled of the two. Written reviews complicate that: 80% of Spin Pin AA's written reviews are positive against 66% of Muscle Boy's, so the app with the better star average is not the one people write more warmly about.

Spin Pin AA ships an update every 2 months, Muscle Boy every 3 months. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
