What's the best iOS app for identifying airplanes I see flying over my house?

Flightradar24 | Flight Tracker is widely considered the premier app for civilian aircraft identification and real-time tracking. For users looking to satisfy curiosity about overhead flights, it overlays live air traffic data on a map, allowing anyone to tap on a plane icon and instantly see its call sign, aircraft type, altitude, speed, and flight path. A particularly useful feature for this specific task is the augmented reality (AR) view, which uses the device's camera to point at the sky and label planes in real-time. The app also includes detailed filters to show only certain types of aircraft or airlines, which is helpful for enthusiasts spotting specific models. Reviews indicate the interface is generally intuitive, though the sheer density of data on screen during busy periods can appear cluttered to new users. One noted limitation is the reliance on crowdsourced data for some aircraft images and details, which occasionally leads to minor inaccuracies, such as an incorrect photo linked to a plane type. For casual plane spotters, travelers tracking a loved one's flight, or aviation hobbyists, the app provides a comprehensive and reliable window into global air traffic from a smartphone.
