There's no official ABR CORE app. RadCore is a mobile-optimized web platform covering all three modules (NIS, RISC, Physics), with 1,500+ practice questions available from any browser.
RadCore can support a study routine across residency: practice a few questions between cases, review a full set during a break, or focus on physics topics during a dedicated session. Performance tracking is available across sessions.
