Regulations, offline & cited
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
The full FAR/AIM, free and offline, with fast search and live citations. Upgrade for study tools and plain-English help that links back to the source.
RegBrief is an iPhone and iPad app that puts the full FAR/AIM offline on your phone, for pilots from student to ATP. Fast full-text search covers the whole library, and after a one-time download it works completely offline, with no account needed.
What's included
• 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 finds any regulation.
• Offline once downloaded, no account, no problem
• Tap any §-reference to jump directly to the cited section
Your ACS study guide
RegBrief ships the FAA Airman Certification Standards for Private, Remote Pilot, Instrument, Commercial, Flight Instructor, and ATP.
• 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.
• Study by certificate: pick your certificate, see only the ACS that applies to you
• Sort tasks by Area
Study tools
• 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 (Plus)
On-device Apple Intelligence
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
• 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.
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.
