# Mobile Multibody Dynamics vs Mechanical Formula

The clearest difference is rating: Mechanical Formula at 4.7 against Mobile Multibody Dynamics's 3.7. Mechanical Formula also leads on ratings volume (34 vs 6) and iOS requirement (13.0 vs 16.0). Mobile Multibody Dynamics's advantage is in-app purchases (none vs 1) and update cadence (monthly vs every 4 months). On price, ads and device support there is nothing between them.

Both are free to download. Mechanical Formula sells 1 one-off in-app purchase. Mobile Multibody Dynamics asks for nothing beyond the download.

Mechanical Formula holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Mechanical Formula has 34 ratings behind it against 6, so its average is the more settled of the two.

Mobile Multibody Dynamics ships an update monthly, Mechanical Formula every 4 months. The most recent releases landed on September 16, 2026 and September 19, 2026 respectively.
