Verdict
Pythagoras Calculator and Math & Trigonometry both sit at 4.6 stars, but that hides the real split: 83% of Pythagoras Calculator's written reviews are positive against 38% of Math & Trigonometry's. Pythagoras Calculator also leads on ratings volume (242 vs 11). Math & Trigonometry's advantage is update cadence (every 5 days vs every 3 weeks) and iOS requirement (9.0 vs 15.0). On price, rating, ads and in-app purchases there is nothing between them.
