The FAR/AIM in your pocket. This app was built specifically for pilots and aviation professionals. It is a one-stop reference for those who are involved with flying. Updates? We do them frequently. About once per month for the regs and 2-3 times a year for the AIM and PC/G. You’ll be much more up-to-date than with the hard copies, which are typically updated only once per year. An in-app subscription grants access to ongoing content updates. Other features: • Free one-week trial for new users. Try it for yourself at no risk with no commitment. • Complete text FAR/AIM, namely 14 CFR, Chapter 1 (FAR) and NTSB 830, and Aeronautical Information Manual (AIM), including charts and images. • Lightning fast browsing. • Intelligent search with full-text and header options. • Context sensitive search (limit search to certain sections). • Bookmarks and user highlights. • Saved search term history. • Email sections to friends. Contents: The complete FAA FAR. Don't be left missing regs. CFR 14 Parts 1, 3, 11, 13, 14, 15, 16, 17, 21, 23, 25, 26, 27, 29, 31, 33, 34, 35, 36, 39, 43, 45, 47, 49, 60, 61, 63, 65, 67, 71, 73, 77, 91, 93, 95, 97, 99, 101, 103, 105, 117, 119, 120, 121, 125, 129, 133, 135, 136, 137, 139, 141, 142, 145, 147, 150, 151, 152, 153, 155, 156, 157, 158, 161, 169, 170, 171, 183, 185, 187, 189, 193, 198.

This is the classic tail number search program, but with a twist. This app works in the air, making it the perfect tool for pilots while aviating or at remote airports. The entire FAA registration database (highly compressed) is included in the app - no cell signal or WiFi hotspot needed. And of course, the database can be updated when back on the ground.

Verdict
The clearest difference is price: FAR/AIM at Free against N Numbers's $0.99. FAR/AIM also leads on rating (4.7 vs 3.2) and update cadence (fortnightly vs every 10 months). N Numbers's advantage is in-app purchases (none vs 1) and iOS requirement (11.0 vs 13.0). On ads and device support there is nothing between them.
