Verdict
The clearest difference is price: Radiology Core at Free against NIS+RISC Prep's $9.99. Radiology Core also leads on iOS requirement (9.0 vs 15.1). NIS+RISC Prep's advantage is update cadence (every 9 days vs every 22 months) and ratings volume (11 vs 1). On rating, review sentiment, ads and in-app purchases there is nothing between them.

Radiology Core is free to download; NIS+RISC Prep costs $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.
