Flight Follower is a real-time flight tracking application built specifically for iOS devices. It allows users to identify aircraft overhead, view live flight status, track planes with native widgets, and explore a fast ADS-B map. The app was created by Dennis Walsh, a pilot and aviation enthusiast, to provide a better flight tracking experience without the frustrations of adware and slow performance found in other trackers.

The app offers several key features including Siri integration that allows users to ask "Hey Siri, what plane is that?" for instant aircraft identification. It provides live aircraft notifications showing the closest aircraft in real-time without constantly checking the app. Home Screen widgets display nearby aircraft at a glance with multiple sizes available. The app includes a native Swift map that's described as blazing fast with smooth scrolling and instant updates. Aircraft details such as type, airline, altitude, speed, and heading are provided for comprehensive flight tracking.

The application works by utilizing ADS-B data from adsb.lol and airplanes.live, which gather information from aircraft transponders to display real-time flight information. The data is updated continuously for accurate tracking. The app uses native iOS integration including Siri Shortcuts, Live Activities, and Home Screen widgets to provide seamless functionality.

Benefits include free core features with no advertisements, making it accessible to all users. The app is designed for plane spotting sessions, family walks where children can identify planes overhead, airport spotting activities, and general aviation tracking. Users appreciate the distraction-free experience and the ability to track flights without paying for basic functionality.

The target audience includes aviation enthusiasts, casual plane spotters, licensed pilots, families interested in aviation, and anyone wanting to identify aircraft overhead. The app integrates with native iOS features including Siri Shortcuts, Live Activities, and Home Screen widgets. It's built using Swift technology for optimal iOS performance and currently only available on iOS platforms.
