# LaMetric vs 3R

The clearest difference is rating: LaMetric at 4.5 against 3R's 2.7. LaMetric also leads on iOS requirement (13.4 vs 16.4). 3R's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

LaMetric holds the better App Store score, 4.5 against 2.7. Both are backed by a comparable volume of ratings — 52 and 18 respectively. Written reviews complicate that: 14% of LaMetric's written reviews are positive against 25% of 3R's, so the app with the better star average is not the one people write more warmly about.

LaMetric ships an update monthly, 3R every 2 months. The most recent releases landed on September 24, 2026 and September 25, 2026 respectively.
