Overhead 1090 turns your own ADS-B receiver into a beautiful live radar picture of the sky above you. No accounts. No subscriptions. No aircraft data leaving your network. If your antenna can hear it, Overhead 1090 shows it — with the low-latency, unfiltered view that only a local receiver can deliver. WHAT YOU GET • Live radar map — every aircraft your receiver hears, updated in real time on a gorgeous dark map • Aircraft details — callsign, registration, type, altitude, speed, heading, and distance from home • Reports — traffic by hour and day, busiest hours, top operators and types • Sightings — a feed of the notable stuff: military contacts, low passes, rare types, new airframes, closest approaches • Logbook — a searchable log of every flight your receiver has heard, each with its ground track • All your receivers — run more than one antenna? Add them all and filter by who heard what • Built for iPad — a full-screen radar display • Apple TV — the living-room big board. Put the sky above your house on the biggest screen you own • Mac — record every flight from the menu bar, with a live chart, Logbook, alerts and desktop widgets • Designed for iPhone Duo — half-fold it for the map above the traffic list • One purchase unlocks iPhone, iPad, Apple TV and Mac WORKS WITH YOUR RECEIVER Overhead 1090 connects to ADS-B receivers on your local network that expose dump1090-compatible data — including popular Raspberry Pi feeder setups. Setup is as simple as pointing the app at your receiver's address; it can even find it for you. No receiver yet? Demo mode lets you explore the full app with realistic sample traffic. WHY LOCAL IS BETTER Internet flight trackers filter, delay, and aggregate. Your receiver doesn't. Overhead 1090 shows exactly what's broadcast over your head the moment it's received — including traffic that never appears on the big tracking sites. PRIVATE BY DESIGN Your aircraft data stays on your network. Overhead 1090 has no analytics, no ads, and no accounts. The app's privacy label is "Data Not Collected." — Overhead 1090 is for hobbyist and educational use. It is not certified for real-world navigation, air traffic control, or safety-of-life use. Requires a dump1090-compatible ADS-B receiver on your local network for live data (demo mode works without one). The app logs traffic while it is open.
