# Ruler Professional vs Ruler

The clearest difference is review sentiment: Ruler Professional at 57% against Ruler's 0%. Ruler Professional also leads on device support (3 vs 1) and iOS requirement (10.0 vs 18.0). Ruler's advantage is in-app purchases (none vs 1) and rating (3.7 vs 3.3). On price, ratings volume, ads and monetization model there is nothing between them.

Both are free to download. Ruler Professional sells 1 one-off in-app purchase. Ruler asks for nothing beyond the download.

Ruler holds the better App Store score, 3.7 against 3.3. Both are backed by a comparable volume of ratings — 3 and 3 respectively. Written reviews complicate that: 57% of Ruler Professional's written reviews are positive against 0% of Ruler's, so the app with the better star average is not the one people write more warmly about.
