Verdict
The clearest difference is price: 14 CFR by LawStack at Free against FAR/AIM by ASA's $19.95. 14 CFR by LawStack also leads on review sentiment (77% vs 33%) and update cadence (every 2 months vs every 5 months). FAR/AIM by ASA's advantage is rating (3.4 vs 2.1) and in-app purchases (none vs 2). On ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
14 CFR by LawStack is free to download; FAR/AIM by ASA costs $19.95 up front. 14 CFR by LawStack sells 2 one-off in-app purchases. FAR/AIM by ASA asks for nothing beyond the download.
FAR/AIM by ASA holds the better App Store score, 3.4 against 2.1. That said, the two scores are not equally well evidenced: FAR/AIM by ASA has 253 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 77% of 14 CFR by LawStack's written reviews are positive against 33% of FAR/AIM by ASA's, so the app with the better star average is not the one people write more warmly about.
14 CFR by LawStack ships an update every 2 months, FAR/AIM by ASA every 5 months. The most recent releases landed on October 2, 2026 and October 22, 2026 respectively.
