ADSBWho

Your receiver speaks seven dialects — we translate all of them. Live map, background alerts, coverage heatmap, moon transits, iCloud sync.

ADSBWho — Your Personal Sky Radar

Ever looked up at a plane and wondered where it's going? ADSBWho turns your iPhone into a powerful aircraft tracking station, giving you real-time data on every flight overhead.

Your Own ADS-B Receiver, Your Own Data ADSBWho is designed to work with your personal ADS-B receiver on your local network. Connect directly to devices like FlightAware PiAware, ADS-B Exchange feeders, or any receiver running dump1090 or readsb. Because the data comes straight from your receiver over your local Wi-Fi, there's no internet dependency and no data usage — everything stays on your home network. For times when you're away from your receiver or want extended range, remote feed support is available too. Use local only, remote only, or both together for maximum coverage.

Live Aircraft Radar Watch planes appear on your map in real time. See callsigns, altitudes, speeds, aircraft types, and registrations at a glance. Local feed updates arrive instantly with no cloud latency — as fast as your receiver can decode them.

Augmented Reality Sky View Point your phone at the sky and see aircraft labels overlaid in AR. Identify flights instantly with callsign, altitude, and distance — right where you're looking. The AR view filters to your configured radius so you only see what matters.

Spotting Log Every aircraft you detect is automatically logged with registration, callsign history, route history, and timestamps. Filter by date range to explore your spotting history — today, last 7 days, last 30 days, or all time. Track how many times you've seen the same aircraft and watch your collection grow.

Moon Transit Predictions A unique feature you won't find anywhere else. ADSBWho calculates whether an aircraft is about to pass in front of the moon from your exact location. Get notified before it happens so you can look up and watch a plane silhouette cross the lunar disc.

Live Activity & Dynamic Island Keep monitoring even when the app is in the background. The lock screen Live Activity and Dynamic Island show your current aircraft count, nearest flight, and distance — all updating in real time without opening the app.

Smart Notifications Receive proximity alerts when aircraft enter your chosen radius. Each notification includes the flight's altitude, distance, and compass direction from your location. Duplicate alerts are suppressed, and ground infrastructure like towers is automatically filtered out.

Detailed Statistics Dive into your data with statistics on most-spotted aircraft, aircraft type breakdowns, busiest spotting days, and more. See which registrations appear most often in your skies.

Aircraft Watchlist Flag specific registrations or hex codes you want to track. Watchlisted aircraft are highlighted on the map with a distinctive ring so you never miss them.

Coverage Map Visualise your ADS-B reception coverage over time. See where your setup performs best and identify gaps in your tracking range.

Built for Enthusiasts Whether you're a seasoned plane spotter running your own receiver, an aviation photographer timing the perfect shot, or just curious about the traffic above your house — ADSBWho gives you the tools to explore the sky like never before.
