# MotionGen vs Mechanical Formula

The clearest difference is review sentiment: MotionGen at 50% against Mechanical Formula's 0%. MotionGen also leads on in-app purchases (none vs 1) and iOS requirement (7.0 vs 13.0). Mechanical Formula's advantage is rating (4.7 vs 3.4). On price, ratings volume, ads and device support there is nothing between them.

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

Mechanical Formula holds the better App Store score, 4.7 against 3.4. Both are backed by a comparable volume of ratings — 15 and 34 respectively. Written reviews complicate that: 50% of MotionGen's written reviews are positive against 0% of Mechanical Formula's, so the app with the better star average is not the one people write more warmly about.
