Know what’s flying near you.
Most drones broadcast Remote ID — position, altitude and the pilot’s location — over Wi-Fi and Bluetooth. LittleSpec listens with its onboard Wi-Fi chip and plots them just like aircraft.

A pocket device for exploring the RF spectrum. The air around you is full of signals - listen in.

A plane spotter, drone finder, boat tracker and signal analyser. In your pocket.
LittleSpec listens with its own antennas. No internet feeds, no dongles, no desktop software — whatever is transmitting nearby, it picks the signal up directly, works out what it is, and shows you. Aircraft and boats on a map, drones and their pilots, key fobs, sensors and radio stations on a live spectrum.
Signal analyser
Watch the airwaves in real time
A live spectrum of everything transmitting around you, from 5 MHz to 1.7 GHz. Peaks rise as devices key up — tune in, zoom, and listen to supported broadcasts.
Plane spotter
Live aircraft, no internet
A dedicated internal 1090 MHz antenna picks up ADS-B broadcasts straight from aircraft overhead and plots them on a map — callsign, altitude, heading and speed.
Drone finder
Hears Remote ID at 2.4 GHz and shows nearby drones on the map — along with where their pilots are standing.
Boat tracker
Picks up AIS from vessels on 162 MHz and plots them live, with names, headings and speeds.
Scanner & listener
Sweep a band, stop on activity and listen in — airband, marine VHF, PMR, ham repeaters and FM radio.
Antennas
Two antennas. Zero fiddling.
Everything LittleSpec shows you comes in over the air, through its own antennas. Inside, one tuned for 1090 MHz ADS-B aircraft tracking — which also picks up strong nearby signals like FM radio. On top, the included wideband extendable antenna on a standard SMA connector for everything else. LittleSpec switches between them automatically.
One pocket device. The whole spectrum.
Everything here is a real thing LittleSpec hears, from drones at 2.4 GHz down to FM radio at 88 — straight off the air, through its own antennas.
Every aircraft overhead. Straight off the air.
Aircraft constantly broadcast their position, identity, altitude and speed. The internal 1090 MHz antenna receives them directly — a live picture of the sky, no internet required.
Your neighbourhood, chattering away.
Key fobs, doorbells, weather stations, tyre sensors — the busiest airspace in any home. LittleSpec catches their short coded bursts, identifies the device, and explains what it just said.
Nearby vessels, plotted live.
Near a coast, river or port? Ships report their name, position and speed over AIS — the maritime cousin of ADS-B. LittleSpec plots the vessels around you as they report in.
The original social network.
Hams have been talking across town — and across continents — for a century. Listen in on local repeaters, nets and calling channels, and watch band activity rise and fall through the day.
Old-school radio, new-school view.
At the bottom of the dial, the classics: every FM station near you appears as a peak on the live spectrum. Tap one to tune in and listen through your phone.
Smart identification. Real decoding.
LittleSpec matches every signal against what it knows — frequency, bandwidth, modulation, timing — and names it with a confidence level. Structured signals like ADS-B, AIS and Remote ID are decoded outright into aircraft, boats and drones on a map. RF expertise not required.
“Car key fob · 433.92 MHz · OOK burst. Short coded transmission, then silence — someone just locked their car nearby.”
Your window into the spectrum.
LittleSpec pairs with your phone over Wi-Fi and Bluetooth — iPhone app first, with Android coming later. The app is where signals get names, aircraft get plotted, and neighbourhoods get heat-mapped.
