All Features

Turns your device into a radio so you can listen to stations in the air.

📶 1 MHz – 6 GHz (commonly 88–108 MHz FM, airband, ham bands)

Shows airplanes flying near you, with their names and how high they are.

📶 1090 MHz

Like plane tracking, but for boats and ships on the water.

📶 161.975 / 162.025 MHz

Hears the little reports your electricity, gas, or water meter sends out.

📶 ~915 MHz ISM (US)

Hears the sensors inside car tyres that report air pressure.

📶 315 MHz (US) / 433.92 MHz (EU)

Reads the temperature and humidity that home weather gadgets send.

📶 433.92 MHz / 868 MHz / 915 MHz

Follows weather balloons that scientists send up into the sky.

Reads short text messages that planes and airlines send each other.

📶 ~129–137 MHz (VHF ACARS)

Turns the beep-beep of Morse code into letters you can read.

📶 Any (HF/VHF ham bands common)

Reads an old kind of radio typing that uses two tones.

📶 HF ham bands (frequency-shift keying)

A big radar-like view that shows where radio signals are hiding across a huge range.

📶 Sweeps up to 1 MHz – 6 GHz

A strength meter that gets louder when you point the antenna at a signal.

📶 Any single frequency

Automatically hops through many frequencies to find the ones that are busy.

📶 User-defined range or frequency list

Shows the picture from old-style TV or drone camera signals.

📶 VHF/UHF video (e.g. FPV bands)

Lists nearby Bluetooth gadgets that are announcing themselves.

📶 2.4 GHz (BLE advertising channels)

Sends sound from the microphone out as a radio signal (only okay on allowed channels).

📶 Typically FM broadcast / ham (region dependent)

Can copy and re-send simple button-remote signals — only for remotes you own.

📶 315 / 433.92 MHz ISM

Can create pager-style messages — only allowed on frequencies you're licensed for.

📶 Licensed paging frequencies only

Adds the little station-name text that shows on car radios (lab use only).

📶 FM broadcast (licensed / dummy-load only)

Plays saved sound clips out as a radio signal (only on allowed channels).

📶 Chosen carrier (licensed / lab only)

Sends beep-beep Morse code messages (best done with a ham radio licence).

📶 Ham bands (with licence)

Sends old-style two-tone radio typing (best with a ham licence).

📶 Ham bands (with licence)

Can make fake airplane signals — extremely illegal outside a sealed lab.

📶 1090 MHz

Sends a ham-radio location postcard (needs a ham licence).

📶 APRS ham frequency (with licence)

Can make pretend GPS signals — only ever inside a sealed test box.

📶 1575.42 MHz (GPS L1)

Makes a hidden 'beep' beacon for a fun find-the-transmitter game.

📶 Ham bands (with licence)

Makes a picture appear on someone's radio waterfall screen — a fun art trick.

📶 Chosen carrier (licensed / lab only)

Can send lots of fake Bluetooth 'hello' messages — annoying and restricted, lab only.

📶 2.4 GHz BLE advertising channels

Blasts noise to block a band. Using it in real life is illegal — shown only to explain jamming.

📶 User-selected band(s)

Quickly jumps a signal between many frequencies — restricted, lab use only.

📶 User-defined range

Plays back sub-GHz recordings saved by a Flipper Zero — only for your own devices.

📶 Sub-GHz (per .sub file)

Records the raw radio waves to the memory card so you can play them back later.

📶 Any (records the tuned slice)

Plays back a saved radio recording by sending it out again (only for your own devices).

📶 Any (as recorded)

Makes a steady test signal so you can check if radios and antennas work.

📶 Any (single carrier)

Your address book for radio channels — save the good ones so you can jump back fast.

📶 n/a

Lets you look at, rename, and delete the files saved on the memory card.

📶 n/a

A simple place to type and save little notes right on the device.

📶 n/a

Shows a picture of a saved recording so you can see the shape of the signal.

📶 n/a (analyses files)

Quickly erases everything on the memory card to start fresh.

📶 n/a

Lets you add or remove extra mini-apps to the device.

📶 n/a

Warns you when there's a strong signal nearby, with a history of what it saw.

📶 Wide (configurable)
