Verdict

The call

The clearest difference is rating: Ruler at 4.3 against Ruler+ Utility's 3.0. Ruler also leads on update cadence (every 7 months vs every 40 months) and ratings volume (136 vs 2). Ruler+ Utility's advantage is review sentiment (47% vs 33%). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Ruler holds the better App Store score, 4.3 against 3.0. That said, the two scores are not equally well evidenced: Ruler has 136 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 33% of Ruler's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Ruler+ Utility ships an update every 40 months, Ruler every 7 months. Both last shipped on October 24, 2026.
