Verdict
The clearest difference is rating: Ruler® at 4.3 against Ruler's 3.5. Ruler® also leads on ads (none vs shown) and ratings volume (35K vs 79). Ruler's advantage is review sentiment (40% vs 22%) and update cadence (every 3 weeks vs every 2 months). On price, in-app purchases, monetization model 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. Ruler® sells 2 in-app purchases, starting at $1.99 per 7 days and Ruler sells 4 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Ruler® holds the better App Store score, 4.3 against 3.5. That said, the two scores are not equally well evidenced: Ruler® has 35K ratings behind it against 79, so its average is the more settled of the two. Written reviews complicate that: 22% of Ruler®'s written reviews are positive against 40% of Ruler's, so the app with the better star average is not the one people write more warmly about.
Ruler® ships an update every 2 months, Ruler every 3 weeks. The most recent releases landed on October 19, 2026 and October 15, 2026 respectively.
