Verdict

The call

The clearest difference is monetization model: Step Gunner at freemium against USMLE Prime's subscription. Step Gunner also leads on ratings volume (24 vs 1) and iOS requirement (17.0 vs 26.2). USMLE Prime's advantage is rating (5.0 vs 4.8). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Step Gunner sells 2 in-app purchases, starting at $9.99 per month and USMLE Prime sells 6 in-app purchases, starting at $49.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

USMLE Prime holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Step Gunner has 24 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
