What it is
Ham Exam Trainer covers the three United States amateur radio licence exams — Technician, General and Amateur Extra — with the complete NCVEC question pools, all 1,431 questions, and the current errata applied.
Every question carries a plain-language explanation of why the right answer is right, rather than a right-answer key to be memorised and forgotten. A spaced-repetition scheduler tracks what you keep getting wrong and brings it back.
Mock exams are assembled the way the real ones are, to the per-element rules. The Android build ships without the internet permission, so none of it depends on a signal and none of it leaves the phone. It is a one-time purchase: no subscription, no ads, no analytics, no accounts.
