Verdict
Quick Graph and MathNotes both sit at 4.6 stars, but that hides the real split: 94% of Quick Graph's written reviews are positive against 33% of MathNotes's. Quick Graph also leads on ratings volume (423 vs 52). MathNotes's advantage is update cadence (every 11 days vs every 5 months) and iOS requirement (15.0 vs 17.0). On price, rating, ads and in-app purchases there is nothing between them.
