Both are free to download. 100cm Ruler sells 1 one-off in-app purchase. Photo Measures Lite asks for nothing beyond the download.
100cm Ruler holds the better App Store score, 4.0 against 2.2. That said, the two scores are not equally well evidenced: Photo Measures Lite has 31 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 49% of Photo Measures Lite's written reviews are positive against 45% of 100cm Ruler's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on August 16, 2026 and June 11, 2026 respectively.
