Verdict
The clearest difference is in-app purchases: USMLE Exam Prep at none against Case Files's 6. USMLE Exam Prep also leads on update cadence (every 4 months vs every 21 months) and iOS requirement (13.0 vs 15.6). Case Files's advantage is ads (none vs shown). On price and device support there is nothing between them.
