The clearest difference is rating: Protractor for Angle Measuring at 4.5 against HM | DCC's 3.0. Protractor for Angle Measuring also leads on update cadence (every 3 weeks vs every 4 months) and ratings volume (1.1K vs 6). HM | DCC's advantage is in-app purchases (none vs 5) and ads (none vs shown). On price, monetization model and device support there is nothing between them.

Protractor for Angle Measuring holds the better App Store score, 4.5 against 3.0.

Written reviews complicate that: 56% of HM | DCC's written reviews are positive against 48% of Protractor for Angle Measuring's, so the app with the better star average is not the one people write more warmly about.
