PlaneWatcher is a travel and navigation app designed specifically for the Apple Watch. With this app, users can easily visualize aircraft around them without having to reach for their phone. It provides worldwide, real-time, unfiltered flight data, thanks to its data provider ADSBExchange, the world's largest source of unfiltered flight data.

One of the standout features of PlaneWatcher is its ability to display all aircraft, unfiltered, unlike most major flight tracking apps. This allows users to have a comprehensive view of the aircraft in their vicinity. The app also offers the option to explore aircraft details such as flight name, registration, type, operator, altitude, speeds, and more, depending on data availability.

PlaneWatcher offers a customizable view with multiple filtering options. Users can filter aircraft by altitude, type, callsign, or registration, and these filters can be combined for more specific results. The app also supports complications, allowing users to easily access it with a single tap.
