Verdict

The call

The clearest difference is rating: USMLE Prime at 5.0 against Step2Drill's 3.9. USMLE Prime also leads on review sentiment (100% vs 86%). Step2Drill's advantage is monetization model (freemium vs subscription) and ratings volume (13 vs 1). On price, ads, in-app purchases and device support there is nothing between them.
