Verdict
The clearest difference is rating: FAR AIM by Flightready at 4.7 against 14 CFR by LawStack's 2.1. FAR AIM by Flightready also leads on ratings volume (561 vs 7) and update cadence (monthly vs every 2 months). 14 CFR by LawStack's advantage is review sentiment (77% vs 44%) and iOS requirement (9.0 vs 15.1). On price, ads, in-app purchases and monetization model 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
Both are free to download. 14 CFR by LawStack sells 2 one-off in-app purchases and FAR AIM by Flightready sells 4 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
FAR AIM by Flightready holds the better App Store score, 4.7 against 2.1. That said, the two scores are not equally well evidenced: FAR AIM by Flightready has 561 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 44% of FAR AIM by Flightready'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 Flightready monthly. The most recent releases landed on October 1, 2026 and September 25, 2026 respectively.
