# USMLE Prime vs USMLE Step 2 CK Prep

The clearest difference is iOS requirement: USMLE Step 2 CK Prep at 17.0 against USMLE Prime's 26.2. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. USMLE Prime sells 6 in-app purchases, starting at $49.99 per month and USMLE Step 2 CK Prep sells 3 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.
