# USMLE Prime vs Tutor Kay

The clearest difference is in-app purchases: Tutor Kay at none against USMLE Prime's 6. Tutor Kay also leads on ratings volume (5 vs 1) and iOS requirement (15.0 vs 26.2). On price, rating, ads 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. Tutor Kay asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for USMLE Prime against 5.0 for Tutor Kay. That said, the two scores are not equally well evidenced: Tutor Kay has 5 ratings behind it against 1, so its average is the more settled of the two.
