# Aerospace Engineering 101 vs Mechanical Formula

The clearest difference is review sentiment: Aerospace Engineering 101 at 67% against Mechanical Formula's 0%. Aerospace Engineering 101 also leads on in-app purchases (none vs 1) and iOS requirement (9.0 vs 13.0). Mechanical Formula's advantage is rating (4.7 vs 4.5). On price, ratings volume and device support there is nothing between them.

Both are free to download. Mechanical Formula sells 1 one-off in-app purchase. Aerospace Engineering 101 asks for nothing beyond the download.

Mechanical Formula holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 51 and 34 respectively. Written reviews complicate that: 67% of Aerospace Engineering 101'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.
