# M Tool vs Span Installer

The clearest difference is review sentiment: M Tool at 50% against Span Installer's 0%. M Tool also leads on device support (3 vs 1) and iOS requirement (9.0 vs 17.6). Span Installer's advantage is rating (3.7 vs 3.0) and ratings volume (13 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Span Installer holds the better App Store score, 3.7 against 3.0. That said, the two scores are not equally well evidenced: Span Installer has 13 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of M Tool's written reviews are positive against 0% of Span Installer's, so the app with the better star average is not the one people write more warmly about.
