Real-time radar alerts
Set your point and a radius up to 80 km: as soon as an aircraft enters the sector you get the alert with callsign, altitude and type, like a real proximity radar.

Behind the scenes of LowPass
A project born from a passion for the sky and for code.
Hi! I'm an Italian student passionate about technology, programming and plane spotting. Often, while outside, I'd look up at the sky, see an aircraft and, out of pure curiosity, want to know where it was headed and much more.
That's how LowPass was born: a bot developed entirely from scratch to offer precise proximity alerts, flight tracking and instant weather data, designed both for demanding spotters and for anyone with a passion for aviation.
