overfly records every aircraft that flies over your home — automatically, continuously, with the registration number, altitude, noise level, and timestamp. Your reports carry legal weight from the moment you verify your email.
"A receiver network used as a legal evidence source needs to be designed like evidence, not like a weather station."
— overfly design principleoverfly combines a home ADS-B receiver with a mobile app and a verified-identity reporting system. Together they produce a record that is technically precise, personally attributed, and legally durable.
A small ADS-B receiver at your home captures every aircraft's transponder broadcast: registration, position, altitude, and speed. It runs without your involvement, even while you sleep.
When an aircraft is disturbing you, open the app and tap. The app matches the sound to the aircraft overhead and records the moment: who, where, how loud, and how much it bothered you — on a 1–5 scale you set yourself.
Your reports are timestamped, tied to your verified email, and exportable as structured data. The combination of passive monitoring and active complaints documents both pattern and impact.
Every log entry captures the full picture of an aircraft event — not just "a plane flew over" but the specific aircraft, its path, and its acoustic impact at your location.
FAA registration (tail number), aircraft type, and operator name — resolved from the official FAA aircraft registry.
Latitude, longitude, altitude, ground speed, and heading at the moment of the event. Accurate to the aircraft's Mode S transponder broadcast.
dB(A) estimate at your location, calculated from slant distance and aircraft type using a standard acoustic propagation model.
Piston aircraft burn leaded aviation fuel (100LL). The app flags events where a piston aircraft's proximity and altitude indicate meaningful lead exhaust exposure at ground level.
Every report carries a precise UTC timestamp and is linked to your verified email address — establishing a chain of custody from event to complaint.
Your complete log exports as structured JSON — ready to attach to an FAA Part 150 comment, a town council submission, or a legal filing.
Some aircraft operators participate in the FAA's Limiting Aircraft Data Displayed (LADD) program, which suppresses their registration from public ADS-B feeds. overfly identifies these aircraft using a receiver that captures raw transponder broadcasts, then cross-references the FAA aircraft registry. When we resolve a LADD aircraft's identity, we record both the identity and the fact that the operator chose to suppress it from public tracking. This combination constitutes a documented attempt to evade civic accountability.
overfly is designed with regulatory and legal use in mind. A noise complaint without supporting data is an anecdote. A noise complaint with timestamped, aircraft-attributed, acoustically-modeled records is evidence.
Identity verification. Email verification links every report to a real person with a real address. Reports submitted to the FAA, airport authorities, or courts are personally attributed.
FAA Part 150 compatibility. The export format is designed to support submissions under FAA Part 150 noise compatibility programs, which require documented noise exposure data from affected residents.
Pattern, not just incident. The passive monitoring system records every flight automatically — not just the ones you notice. This establishes cumulative exposure over time, which is the basis for most regulatory noise standards.
Primary source data. Positions come directly from ADS-B transponder broadcasts, not from a third-party aggregator. The receiver is at your address. There is no intermediary between the aircraft's broadcast and your record.
overfly records aircraft behavior — not resident behavior. Your log is stored on your device. It is only transmitted when you choose to submit a report.
Your log entries are stored on your device. No account required to use the app. No background data collection.
Manual log entries are only sent to overfly.report when you explicitly tap to log a plane. Passive monitoring (the automatic background scanner) runs on our secure servers and stores only aircraft positions — never your GPS location.
Your data exports as standard JSON at any time. You can move it to another device, share it with a lawyer, or delete it. No lock-in.
overfly currently serves Pennington and Hopewell Township, New Jersey (ZIP codes 08534, 08525, 08560). The receiver network covers a roughly 8-mile radius centered on Woosamonsa Road, with particular focus on the KTTN (Trenton-Mercer Airport) flight corridors.
Yes. The manual log — tapping when a plane bothers you — works anywhere and does not require a local receiver. You can document aircraft, export your log, and submit complaints based on your own observations. The automatic passive monitoring (background scanning) requires a receiver in your area.
Fill out our coverage request form. We'll contact you when coverage reaches your area, or to discuss setting up a dedicated receiver at your home (~$300 one-time, self-installed).
A receiver is a small software-defined radio (SDR) device — roughly the size of a USB drive — connected to a Raspberry Pi computer. It picks up the ADS-B radio signals that aircraft transponders broadcast continuously. Cost: approximately $300. You do not need a receiver to use the app; you only need one to enable 24/7 automatic monitoring at your specific address.
Some aircraft operators enroll in the FAA's Limiting Aircraft Data Displayed (LADD) program, which suppresses their registration number from public flight-tracking services. These aircraft are still legally required to broadcast their transponder signal — overfly captures that signal and identifies them using the FAA aircraft registry. When the app shows a LADD flag, it means the operator deliberately chose to hide their identity from public view, while continuing to fly over residential neighborhoods.
Your manually-logged entries are stored on your device and sent to our servers only when you choose to submit them. Your email address is collected only for verification and is used to attach legal identity to your reports — it is never sold or shared. Passive monitoring stores aircraft positions and noise estimates; it does not track your GPS location.
When you verify your email, every subsequent report is timestamped and linked to a verified identity with a known address. The data includes the aircraft's FAA registration number, altitude, estimated noise level, and your GPS location at the time of logging. This combination is suitable for submission under FAA Part 150 noise compatibility programs, town council filings, or legal proceedings. Your export file is structured JSON — readable by lawyers, regulators, and journalists.
overfly works on any modern phone as an installable web app. No app store required.
