iatroX (US) is more focused. Its Step 3 value lies in AI-adaptive sequencing, repeated active recall, and spaced repetition designed to keep revision efficient when time is fragmented.

When To Use Each

  • Choose AMBOSS when:

    • you want Step 3 preparation plus a broader clinical knowledge resource,
