# Case Files vs USMLE

The clearest difference is update cadence: USMLE at every 6 weeks against Case Files's every 21 months. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Case Files sells 6 in-app purchases, starting at $9.99 per 7 days and USMLE sells 1 in-app purchase, starting at $49.99 per month. Whichever you choose, the download price is not the number that matters.

Case Files ships an update every 21 months, USMLE every 6 weeks. The most recent releases landed on October 24, 2026 and November 2, 2026 respectively.
