Flightradar24 is a flight tracking app that allows users to track flights in real-time on a detailed map. The app offers a range of features, including historical data, playback of past flights, arrival and departure boards, flight status, aircraft on the ground, current delay stats, and detailed weather conditions. Users can search for individual flights using flight number, airport, or airline, and filter flights by airline, aircraft, altitude, speed, and more. The app is free, but there are two upgrade options—Silver and Gold—that come with a free trial.

Flightradar24 Silver includes 90 days of flight tracking history, more aircraft details, filters and alerts to find and track the flights you’re interested in, and current weather at 3,000+ airports overlaid on the map. Flightradar24 Gold includes all the features included in Flightradar24 Silver, plus 365 days of flight history, detailed live map weather layers, aeronautical charts and oceanic tracks, air traffic control boundaries, and extended Mode S data.

The app uses ADS-B transponders that transmit positional data, and Flightradar24 has a rapidly growing network of over 20,000 ground stations around the world to receive this data that then shows up as aircraft moving on a map in the app. Coverage is variable and subject to change at any time. Users can contact the developer directly via email, Twitter, or Facebook for feedback. However, the use of this app is strictly limited to entertainment purposes, and the developer will not be held responsible for incidents resulting from the use of the data or its interpretation or its use contrary to this agreement.
