Ruler's advantage is ratings volume (413 vs 1) and rating (4.2 vs 4.0). On price, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Ruler holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Ruler has 413 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of EC Ruler'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.
EC Ruler ships an update every 2 months, Ruler every 14 months. The most recent releases landed on October 3, 2026 and October 14, 2026 respectively.
