Verdict

The call

ACOG and USMLE both sit at 4.9 stars, but that hides the real split: 90% of ACOG's written reviews are positive against 49% of USMLE's. ACOG also leads on in-app purchases (none vs 1). USMLE's advantage is update cadence (every 6 weeks vs every 3 months) and iOS requirement (15.0 vs 17.0). On price, rating, ratings volume and ads there is nothing between them.
