The Best Plane Tracker for Knowing What's Flying Over You Right Now

Last updated: April 2026

Most flight tracker apps answer one question: where is my flight?

That's useful if you're waiting at arrivals or checking whether your gate has changed. But a growing number of people open a flight tracker for a completely different reason — not to check on a specific flight, but to look up at the sky and wonder: what is that plane?

If that's what you're looking for, the standard flight trackers are not built for you. This guide covers what separates a general flight tracker from a plane identification app, what to look for depending on how you actually use it, and why the "what's overhead" use case deserves its own approach.

What Is a Flight Tracker?

A flight tracker is an app or website that displays the real-time position of aircraft using data broadcast by the planes themselves. Most commercial aircraft are equipped with ADS-B transponders — technology that continuously broadcasts each aircraft's position, altitude, speed, heading, and identity via satellite navigation. This data is picked up by ground-based and satellite receivers and fed into flight-tracking platforms.

The result is the map of moving plane icons you've seen on apps like Flightradar24: thousands of aircraft, updated in near real-time, spanning the entire globe.

Two Very Different Reasons to Track a Plane

Before choosing a flight tracker, it's worth being clear about what you're actually trying to do. There are two distinct use cases, and most apps are built primarily for one of them.

1. Tracking a Specific Flight

You have a flight number — maybe your own upcoming trip, or a family member landing in an hour. You want to know:

Apps like Flightradar24, Flighty, and FlightAware are purpose-built for this. They're excellent at it. You search a flight number, pull up the route, and get status alerts. If this is your primary need, any of the major apps will serve you well.

2. Identifying the Plane Overhead

You hear an engine and look up. Or you're sitting in the garden and a plane crosses overhead. Or you're watching the news after an aviation story and want to understand what type of aircraft looks like what. You want to know:

This is a fundamentally different question. You don't have a flight number. You don't know the airline. You just have a direction and a noise. The major flight trackers can answer this — but they require you to pan across a busy global map and try to tap the right moving dot among dozens. It's not what they're designed for.

This is the gap that a plane identification app fills.

What to Look For in a Plane Tracker (For the Overhead Use Case)

If you want to know what's flying over you right now, these are the features that matter:

Location-First Design

The app should immediately show you the aircraft closest to your current position — without you having to search, zoom, or pan. Your location is the starting point, not a filter you apply later.

Instant Aircraft Identification

You should be able to see the aircraft model, airline, registration, and callsign within seconds of opening the app. The more friction between opening the app and getting an answer, the less useful it is for the overhead use case.

A Home-Screen Widget

This is arguably the most important feature for people who track overhead aircraft casually. If you have to unlock your phone, open an app, wait for it to load, and then navigate to your location — the plane will have gone. A home-screen widget that shows the nearest aircraft at a glance, without opening anything, changes the experience entirely.

Distance and Bearing

Knowing that a plane is 4.2 miles away at your 2 o'clock position at 28,000 feet tells you something useful about where to look. A widget or app that shows raw flight numbers without spatial context isn't much help when you're staring at the sky.

Clean, Minimal Interface

General flight trackers show the entire world's air traffic simultaneously. That's the point — they're global tools. But for identifying a single aircraft overhead, all that noise is a distraction. A cleaner, location-focused interface makes it faster to get to the answer you actually want.

How What Plane Approaches This Differently

What Plane is an iPhone app built specifically around the overhead identification use case.

Rather than showing you a global map of all air traffic, it focuses on what's nearest to you right now: the aircraft model, airline, distance, altitude, heading, and speed of the planes in your immediate vicinity.

The home-screen widget is the defining feature. Glance at your iPhone home screen and you'll see the closest aircraft at that moment — updated without unlocking your phone or opening an app. For people who find themselves regularly looking up and wondering, this removes every layer of friction between the question and the answer.

The widget also works in-flight. If you're a passenger wondering what's above or below you — the model, the airline, the route — What Plane can tell you that too.

What All Flight Trackers Have in Common

Regardless of which app you use, it's worth understanding the data that powers all of them.

ADS-B: The Technology Behind Plane Tracking

ADS-B (Automatic Dependent Surveillance-Broadcast) is the system most consumer flight trackers rely on. Aircraft equipped with ADS-B Out transponders continuously broadcast their position, altitude, speed, heading, and a unique ICAO aircraft address. This data travels on 1090 MHz and can be received by anyone with a compatible receiver — which is how thousands of volunteers around the world contribute to crowdsourced flight-tracking networks.

Because ADS-B data is not encrypted, it can be read by any receiver. This is why a simple app on your phone can tell you, in real time, that the aircraft overhead is a Boeing 737-800 operated by Ryanair, currently at 31,000 feet, heading towards Dublin at 462 knots.

Why Some Planes Don't Show Up

Not every aircraft appears on consumer flight trackers, and there are several reasons why:

Military aircraft frequently operate without broadcasting ADS-B data, or use restricted codes that consumer apps don't display. If a fast jet passes overhead and doesn't appear on your tracker, this is why.

Some private jets can request to have their data filtered from public feeds — in the US, for example, the FAA's LADD programme (Limiting Aircraft Data Displayed) allows operators to block their data from third-party services.

Small general aviation aircraft may not be fitted with ADS-B Out equipment, particularly older aircraft.

Helicopters are sometimes tracked and sometimes not, depending on their equipment and the network coverage in the area.

Very low altitude aircraft may fall outside receiver range in some areas, particularly in rural locations.

If a plane doesn't show up on your tracker, it doesn't mean the app is wrong — it usually means the aircraft is operating outside the standard broadcast parameters.

Common Questions About Flight Tracking Apps

Is flight tracking data real-time?

Near real-time. Most consumer apps display data with a delay of a few seconds to around 30 seconds, depending on the data source and network. For commercial aviation, this is close enough to real-time to be genuinely useful.

Do I need a subscription to track planes?

Most major flight trackers offer a useful free tier. Paid subscriptions typically unlock features like extended flight history, detailed airport statistics, weather overlays, and ad-free experience. For simply identifying what's overhead, a free tier is usually sufficient.

Can I use a flight tracker to identify a plane without a flight number?

Yes — this is exactly what location-based tracking does. Rather than searching by flight number, you let the app use your GPS position and show you the nearest aircraft. You don't need to know anything about the flight in advance.

What is the difference between a flight number and an aircraft registration?

A flight number (e.g., BA249) is a commercial identifier — it refers to a scheduled service on a particular route, operated by a particular airline. The same flight number runs every day, potentially on different aircraft. The aircraft registration (e.g., G-XLEL) is the permanent, unique identifier of a specific physical aircraft — the equivalent of a vehicle's licence plate. For aviation enthusiasts and planespotters, the registration is the definitive identifier.

Are military planes on flight trackers?

Occasionally. Some military transport aircraft, refuelling tankers, and training flights do broadcast ADS-B data and appear on consumer trackers. Combat aircraft and classified operations typically do not. Specialist military tracking networks exist but are separate from consumer apps.

The Right Tool for the Right Question

Flight trackers and plane identification apps serve overlapping but distinct needs:

If you're a traveller checking on your own or someone else's flight — go with Flightradar24, Flighty, or FlightAware. They're optimised for that use case and excellent at it.

If you're someone who regularly looks up at the sky and wants to know what's overhead — an app with a home-screen widget and location-first design is the better fit. That's what What Plane is built for.

The best plane tracker isn't necessarily the one with the most data. It's the one that answers your actual question, as quickly as possible, with as little friction as possible.

For most people who find themselves searching "what is that plane overhead" — that's a glanceable widget, not a global map.

Find Out What's Above You Right Now

What Plane shows the nearest aircraft to your location — aircraft model, airline, altitude, distance, heading, and speed — directly from your iPhone home screen.
