# Math Duel vs DIY Human Body

The clearest difference is rating: Math Duel at 4.5 against DIY Human Body's 3.6. Math Duel also leads on ratings volume (235 vs 5).

Both are free to download. Math Duel sells 1 one-off in-app purchase. DIY Human Body asks for nothing beyond the download.

Math Duel holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: Math Duel has 235 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 64% of Math Duel's written reviews are positive against 75% of DIY Human Body's, so the app with the better star average is not the one people write more warmly about.
