Built the way the examiners build it

Practice exams that mirror the real paper The real number of questions, one drawn from each key topic, the real passing score and a timer. No feedback until the end, then a review of every missed question with your answer beside the right one.

Spaced repetition What you miss comes back tomorrow, collected in a Due tab, alongside flashcards and the same study modes on every element.

A readiness estimate A straight answer to “am I ready to book the exam?”, computed per element from what you have learned, your recent practice exams and your retention. It is an estimate from your own study record, not a guarantee.

Sources you can check Each pool’s approval date, FCC link and SHA-256 hash of the source document are shown in the app, so the claim is checkable rather than merely asserted.

The app stores everything on your device, has no server, collects nothing and works with no network connection. You can export your whole study history as JSON or CSV from Settings.

Element 1 free, the rest one payment

GROL Exam Prep is free to download. Element 1, all 144 questions, stays free forever with the same study modes, flashcards and practice exams as every other element. A single $14.99 purchase unlocks the remaining elements (3, 6, 7, 7R, 8 and 9) with their figures. There is no subscription, no account and no advertising, and Family Sharing is on.

On iPhone and iPad the same pools are inside Band Plan & GROL Exam Prep, an amateur radio reference app. It is $2.99 with the exam prep included and no in-app purchase.

Most of the question pools date from 2009 to 2021 and are nonetheless the pools in force. Confirm with your COLEM that no newer pool has been adopted before you sit.
