Description
Turn your Android device into a versatile software-defined radio receiver. Connect an RTL-SDR over USB and tune in to live radio signals wherever you are.
SDR Touch lets nearly any Android phone or tablet detect and decode a range of live signals and broadcasts through live radio transmission, using a USB-compatible RTL-SDR device.
SDR Touch lets you explore AM, FM, aviation, amateur, digital, and other broadcast signals right on your mobile device. Beyond simply listening to the airwaves, you can also analyze digital radio communication and weather broadcast information.
Detect Signals with Your Android Device
Software-defined radio (SDR) removes the need for dedicated receiver hardware, since nearly every radio function can be handled and controlled digitally. With SDR Touch, all you need to receive and process live signals is an SDR USB device and a suitable antenna.
Connect your SDR USB device through USB On-the-Go (OTG), open the app, and select a frequency to start detecting signals.
