## What is RegBrief?

The complete FAR/AIM — always at hand, with Apple Intelligence on call.

RegBrief puts the full Federal Aviation Regulations and Aeronautical Information Manual on your iPhone and iPad, with fast full-text search and on-device AI to help you actually understand what you are reading.

Everything you need. Nothing you don't.
• Full 14 CFR (all aviation-relevant parts), 49 CFR Part 830, the AIM with color figures, and the Pilot/Controller Glossary
• Selected Advisory Circulars covering aviation weather, pilot certification, stall and spin awareness, collision avoidance, and non-towered airport operations
• Fast full-text search — find any regulation in milliseconds
• Always at hand — no signal, no account, no problem
• Tap any §-reference to jump directly to the cited section

Your ACS study guide
RegBrief ships the full FAA Airman Certification Standards for every certificate and rating — Private, Instrument, Commercial, Flight Instructor, and ATP across Airplane, Helicopter, Glider, Powered-Lift, and LTA variants.
• Read the ACS top-to-bottom: Areas of Operation, Tasks, Knowledge / Risk / Skill elements
• Every element links to the live FAR / AIM / AC section the FAA cites — tap a citation chip to read the source inline
• Cert-tailored: pick your certificate, see only the ACS that applies to you
• Sort tasks by Area, search by ACS code (PA.I.A.K1, IR.III.A.S1)

Built for how pilots actually study
• Highlight text, add notes, and bookmark sections (Plus)
• Bookmarks, highlights, and notes sync across your devices via iCloud
• Reading history keeps your place automatically
• Filter content by certificate (Private, Sport, Remote/Part 107, Instrument, Commercial, CFI, ATP, Mechanic)
• See exactly what changed when regulations are updated

Apple Intelligence on call
With Plus, on Apple Intelligence-capable hardware, RegBrief uses Apple Foundation Models on-device:
• Plain-English RegBriefs — every section gets a plain-English RegBrief, plus tap any subsection for a focused brief on just that part of a long rule
• AI-enhanced search — results re-rank to surface the section that actually answers your question
• Selection RegBriefs — highlight any passage and get a plain-English explanation in place
On-device Apple Intelligence features run entirely on your device. The regulation text and the generated RegBrief never leave your phone.

Need more? Upgrade to Pro
Pro adds a cloud-powered Q&A service: ask any FAR/AIM question in plain English and get an answer with citations to the cited sections. Pro Q&A is the only feature that requires an internet connection, and it works on every iOS 18+ device — Apple Intelligence not required.

Three tiers. Start free.
The full regulation library is free — all text, all search, no cost. Upgrade for more:

Free: Full regulation text, full-text search, study-by-certificate filtering, reading history. Always free.
Plus: $2.99/month or $19.99/year — bookmarks, highlights, notes, change tracking, export, custom collections, and on-device Apple Intelligence features.
Pro: $5.99/month or $39.99/year — everything in Plus, plus cloud Q&A for deeper regulatory questions. Pro Q&A sends your question and, when applicable, the section ID you are reading. No name, email, device identifier, or certificate selection is sent.

Annual Plus and annual Pro include a 7-day free trial. Monthly Plus and monthly Pro start billing immediately. Cancel anytime.

Designed for student pilots, certificated pilots, flight instructors, and aviation mechanics — anyone who works with the regs.

## Version history (last 5 releases)

### 1.10 — 2026-08-20

Try an annual Plus or Pro plan free for 14 days before you're ever charged.

- New annual Plus and Pro subscriptions now start with a 14-day free trial, with a simple timeline showing when it started and when you'll be charged.

### 1.9 — 2026-08-08

Bug fixes and performance improvements.

### 1.8 — 2026-07-17

AIM browsing now drills all the way down — Chapter, then Section, then paragraph — with a breadcrumb in the Reader so you always know where you are.

Study's "Start Reading" card is now a swipeable pager. Tap it on any ACS task and swipe through every cited regulation, one section per page, without backing out to the task list.

Share a link straight to a section from the Reader. More citations are tappable too — spelled-out "14 CFR section N.N" references in the AIM now link like every other cross-reference.

Ask AI shows a one-time notice before your first cloud question, naming exactly what's sent and to whom.

### 1.7 — 2026-06-01

Reg of the Day: the Browse home now opens with a daily ACS-referenced regulation you can open with one tap. A good one to read before you fly.

Cross-reference links got smarter. Multi-section citations like "§§ 91.126 and 91.127" now link every section in the string, and "subpart X of this part" references are tappable too. The specific case in §91.129 that was missing a link is fixed.

Offer codes: you can now redeem a code from your flight school or CFI from the App Store menu.

The 7-day free trial now applies to annual Plus and annual Pro — not just monthly plans.

### 1.6 — 2026-05-25

This update brings performance and reliability improvements for a smoother, more dependable experience.
