SDR Touch allows connecting hardware SDR receivers to Android via a USB cable. Turn any mobile phone or tablet with USB host/OTG support into a portable software defined radio scanner and a spectrum analyser. Driver support exist for RTL-SDR, NeSDR, SDRplay and HackRF.

Listen and record live over-the-air FM stereo radio stations with RDS, weather reports, emergency stations, taxi traffic, airplane communications, audio of analogue TV broadcasts, HAM radio amateurs, digital broadcasts and many more! Depending on hardware used, radio frequency coverage can span from 20 MHz to 2.2 GHz. SDR Touch demodulates broadcast FM, AM, narrowband FM, upper sideband (USB) and lower sideband (LSB) signals.

The built-in RDS monitor will allow exploring the hidden digital data feed that most commercial FM radio stations broadcast. This includes the station's program type (PTY), country of broadcast (ECC), date and time (CT), unique program identifier (PI), list of alternative frequencies (AF) and advanced statistics about the digital RDS carrier signal.

SDR Touch receives live radio via external USB hardware. The app runs offline and does not require a data plan or an internet connection! Take SDR Touch anywhere and find out what hides in the radio spectrum!

In order to run SDR Touch, you will need to plug your SDR receiver into the Android device using an USB OTG cable.

User reviews

Been using this app reliably for a year now and have not encountered any problems with it. Works well on my S21 ultra and Tab 6 with little interference/noise and receives well attached to a £35 amazon discone antenna. Although my RTL SDR dongle does need an inline narrowband filter for specific frequencies like CB and DVB reception.

This app is so close to being something amazing. Unfortunately I'm having issues getting frequencies to save correctly. When recalling a saved frequency it tunes an incorrect frequency. App is also very buggy. Scrolling ghe bad will suddenly stop until you zoom out or move the tuning marker. A paid app should be polished and bug free.

Teddy Johnson, 2023-03-30

Been using this app on my Samsung Galaxy S21 Ultra, works great with my SDR dongle. Steve Fury posted that you are unable to switch channels quickly, this is not the case. There is an JUMP button that allows you to manually enter the frequency you want to go to. Going to pick up a tablet as I would like to see this on a larger screen.
