ReceptionRating · Positive reviews · Number of ratings

Triangle Calculators holds the better App Store score, 5.0 against 4.6.

Written reviews complicate that: 83% of Pythagoras Calculator's written reviews are positive against 0% of Triangle Calculators's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency
