## Description

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.

## Review summary

User feedback centers on the app's core strength—an offline FAA registration database for quick N-number lookups—paired with concerns that the data is out-of-date and the app seems abandoned. While many praise fast, offline access to ownership and aircraft type information, several reviews note updates stopped years ago, causing inaccuracies and limited coverage for newer aircraft. Some users miss features that were removed (history tools, download, share/email) and request refreshed data, more frequent updates, and added search/history capabilities. Overall, it's a useful offline reference when data is current, but reliability suffers without updates.

### Pros

- Offline in-app database enabling lookups without internet
- Fast N-number search returning ownership and aircraft type information
- Uses FAA registration data in compressed format for local access
- Handy quick-reference tool for pilots and aviation enthusiasts
- Longstanding utility for quick tail-number checks

### Cons

- Data is out-of-date and infrequently updated
- Limited coverage for newer aircraft; some searches return old data
- App appears abandoned with no recent updates and features removed
- Inaccuracies due to stale ownership information
- Underdeveloped history/search features and missing functionality (e.g., download, email/log export)
