# REDCap Mobile App vs USMLE

The clearest difference is in-app purchases: REDCap Mobile App at none against USMLE's 1. REDCap Mobile App also leads on iOS requirement (11.0 vs 15.0). USMLE's advantage is ratings volume (5K vs 4) and review sentiment (49% vs 25%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. USMLE sells 1 in-app purchase, starting at $49.99 per month. REDCap Mobile App asks for nothing beyond the download.

USMLE holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: USMLE has 5K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 25% of REDCap Mobile App's written reviews are positive against 49% of USMLE's.

REDCap Mobile App ships an update every 3 weeks, USMLE every 6 weeks. The most recent releases landed on September 11, 2026 and September 25, 2026 respectively.
