Plane Finder tracks live air traffic using ADS-B data, covers commercial and general aviation flights, and has a flight detail view styled like a digital boarding pass. In theory, it's an excellent tool. In practice, Plane Finder's ad experience is frustrating, light mode costs extra, and other apps do everything it does—but better.
I tested it alongside five other apps for WhistleOut's roundup of the best flight tracking apps. Here's where it falls short, and the one use-case that might still find it worth downloading.
Free for iOS and Android.
Premium subscription available.
What is Plane Finder?
Plane Finder is a live flight tracking app available on iOS and Android that uses ADS-B (Automatic Dependent Surveillance-Broadcast) data to display aircraft positions in real time.
It covers commercial flights, private planes, and general aviation, and allows users to search for specific flights or browse air traffic across a map. It also participates in a network of ADS-B ground receivers, which adds some niche value for aviation hobbyists who want to contribute to that infrastructure.

The interface: Fine in theory, frustrating in practice
The map itself is workable, but the quality isn't on the same level as Flightradar24. The default view looks overwhelming and takes some adjusting in settings before it feels comfortable. That's not a fatal flaw, but it contributes to a first impression that doesn't inspire confidence.
The ad experience is where things get more annoying. There's a permanent banner ad at the bottom of the screen that's easy to tap by accident, especially when you're zooming or scrolling the map. Full-screen ads don't have an obvious close button. Compare that to Flightradar24, where the free version ads are unobtrusive, and you feel the difference immediately.

The biggest problem with Plane Finder is that light mode is locked behind a premium subscription. Light mode should be a basic display preference, not a premium feature. But Plane Finder putting it behind a paywall is an unusual call that's going to frustrate a significant portion of users who prefer it for readability, especially outdoors. The 3D flight watch is also similarly restricted.

Is Plane Finder for you?
If you're a general traveler looking for a flight tracker to use on your next trip, Flightradar24 is the better free option in every way. Better map quality, better ad experience, light mode included, and a smoother interface overall.
Plane Finder might be more useful in the ADS-B receiver community. The app is built around contributing to and consuming data from a network of ADS-B feeders, and it includes tools specifically useful for general aviation pilots and enthusiasts who want to interact with that infrastructure. If that describes you, Plane Finder is ideal. For everyone else, there are better options at the same price (free).
What does Reddit think about Plane Finder?
Plane Finder comes up most often in aviation enthusiast and ADS-B communities rather than general travel forums. u/OutrageousExternal on r/ADSB noted, "Plane Finder uses a combination of radar reports and live ADS-B tracking... it also has the tools to be of value for general aviation pilots."

Plane Finder: FAQ
Is Plane Finder free?
Plane Finder is free, but light mode and 3D flight watch require a premium subscription, which is an unusual limitation compared to other free trackers. Most travelers will find the free tier frustrating enough to look elsewhere.
How does Plane Finder compare to Flightradar24?
Flightradar24 is better in almost every area for general travelers: smoother map, better free-tier experience, less intrusive ads, and no paywall on display preferences. Plane Finder has niche value for ADS-B network participants and general aviation pilots.
What is ADS-B and why does it matter for flight tracking?
ADS-B stands for Automatic Dependent Surveillance-Broadcast. It's a system where aircraft continuously broadcast their position, altitude, and speed to ground receivers, which apps like Plane Finder and Flightradar24 use to display live air traffic.
Is Plane Finder good for spotting planes?
It works for plane spotting, but Flightradar24 is the better tool for that use case. Flightradar24's map quality is higher, the interface is smoother, and its AR feature lets you identify planes overhead by pointing your camera at the sky.
