Construction Master Pro Calc also leads on rating (4.8 vs 3.0) and ratings volume (40K vs 2). Metric Conversions Premium's advantage is in-app purchases (none vs 20).

Construction Master Pro Calc is free to download; Metric Conversions Premium costs $4.99 up front. Construction Master Pro Calc sells 12 in-app purchases, starting at $3.69 per month. Metric Conversions Premium asks for nothing beyond the download.

Construction Master Pro Calc holds the better App Store score, 4.8 against 3.0.

Written reviews complicate that: 60% of Construction Master Pro Calc's written reviews are positive against 67% of Metric Conversions Premium's, so the app with the better star average is not the one people write more warmly about.
