Current question pools, or your practice is wasted
The FCC question pools rotate. Study an expired one and you will sit the exam having memorised questions that are no longer on it. SEVENTY3 uses the 2026–2030 Technician pool, current as of July 1, 2026, plus the newest published revision of the General and Amateur Extra pools.
Here is exactly what you get, with the revision date for each, so you can check it against NCVEC yourself.
| Element | Questions | Exam | Pass | Pool valid | Revision |
|---|---|---|---|---|---|
| Technician free | 409 | 35 | 26 | 2026–2030 | 19 Feb 2026 errata |
| General | 423 | 35 | 26 | 2023–2027 | 6th errata, 4 Feb 2026 |
| Amateur Extra | 599 | 50 | 37 | 2024–2028 | 4th errata, 4 Feb 2026 |
Questions come word for word from the official NCVEC documents, and every pool is checked against a second independent copy before it ships. When a pool rotates, you get the new one free.
A look inside the app
Real screenshots, not mockups.
Everything you need to pass, in one app
Full-length practice exams
Take a real 35-question Technician or General exam, or a 50-question Amateur Extra, drawn the same way a volunteer examiner draws yours: one question from every group in the pool. Score it, see what you missed, take another.
Know when you are actually ready
SEVENTY3 tracks how you are scoring and shows you where you stand against the 74 percent you need to pass. You will know whether to book the exam or keep studying, instead of guessing.
Study hands-free in the car
Questions and answers read aloud at whatever speed suits you, so a commute or a walk turns into a study session. No screen needed.
Drill the questions you keep missing
Get one wrong and it comes back sooner. Get it right repeatedly and it fades out. Your study time goes to your weak areas instead of the material you already know.
Easy to read, easy to hear
Large type that scales as far as you need it, high contrast, and full VoiceOver support on every screen. Nobody should fail an exam because they could not read the app.
Works with no signal, keeps no data
Everything lives on your phone, including the diagrams, so it works in a basement, on a plane, or at a hamfest with no bars. No account, no tracking, nothing uploaded.

Frequently asked questions
Are SEVENTY3 practice tests like the real ham radio exam?
Yes. The questions are the real ones. US amateur radio exams are drawn from published question pools, and every question in the app is taken word for word from the current pool. A practice exam here is built the same way a volunteer examiner builds yours, with one question pulled from each group, so the length, the mix, and the 74 percent pass mark all match.
Is the Technician practice test really free?
Yes, and it stays free. You get all 409 Technician questions and unlimited full-length practice exams without paying anything. Only the General and Amateur Extra pools are behind the one-time $9.99 unlock.
Where do the questions come from?
From the question pools published by the National Conference of Volunteer Examiner Coordinators, which are public domain. Every pool is taken straight from the official document and checked against a second independent copy before it ships, so the answer keys are right. Wording is never edited or reworded.
Which question pools are in the app?
The 2026–2030 Technician pool current as of 1 July 2026, the 2023–2027 General pool, and the 2024–2028 Amateur Extra pool, each at its newest published revision. When a pool rotates you get the replacement in a free update.
Can I study without an internet connection?
Yes, completely. Every question and every exam diagram is stored on your phone, so it works on a plane, in a basement, or anywhere with no signal. The app makes no network calls while you study.
Does the app explain the answers?
Yes. Every question has a plain-English explanation of why the correct answer is correct, and Elmer, the built-in tutor, will rephrase it if you want it put another way. Elmer runs entirely on your phone, so it works offline and nothing you ask leaves the device.
The explanations are first drafts and are labelled as such in the app until they have been checked line by line. The questions and answer keys are not drafts: those come straight from the official FCC pools and are correct.
Are you affiliated with the ARRL, NCVEC, or the FCC?
No. SEVENTY3 is an independent study aid. It is not affiliated with, endorsed by, or approved by any of those organisations.
Is there an Android version?
Not yet. SEVENTY3 is on iPhone first.
Why is it called SEVENTY3?
73 is the sign-off operators have used since the telegraph. It means best regards. It seemed like the right name for something whose job is to get you on the air.
