# Ruler+ Utility vs Ruler

The clearest difference is rating: Ruler at 4.2 against Ruler+ Utility's 3.0. Ruler also leads on in-app purchases (none vs 1) and ratings volume (413 vs 2). Ruler+ Utility's advantage is review sentiment (47% vs 17%). On price, ads, device support and iOS requirement there is nothing between them.

Ruler holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: Ruler has 413 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 47% of Ruler+ Utility's written reviews are positive against 17% of Ruler's, so the app with the better star average is not the one people write more warmly about.
