About this app

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.

Ratings and reviews

Not sure why this gets so much hate. If you have the right dongle and the driver for Android then it works. The UI is simple and doesn't really hold your hand. But it's also light weight with less to break and learn to use. But still has all the essentials I feel if you know what you are doing and want to get out of this setup it works well. Im using it for emergencies when the cell/internet go out. So far I'm happily surprised. Plus you don't need to root your phone for it to work.

While the app works well on my phone it freezes a lot on my tablet. It works on some Android Mini PC's but not on others saying the device has to be rooted although that's not true. Also, features like the spectrum display can't be used unless you pay them $10.50. There are several problems using this, there's no way to zoom in or expand the display to make it easy to tune in narrow stations and it doesn't remember the presets but it's the only game in town! There are some other apps for SDR r

Don't Buy! Works when you first install and the companion driver. Later prompts to buy, but navigation to refuse doesn't function, while purchasing works fine. Otherwise phone is locked up. Is this the secret to million + sales? I can write App to do this, could someone else? While app runs tuning has two modes. Those being, adjust bandwidth, and adjust frequency. Each mode works such is easy to use, but switching between modes only ever happens accidentally. I never figured out how to use.
