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 a USB-supported 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 communications and weather broadcast data.
Detect Signals with Your Android Device
Software-defined radio (SDR) removes the need for dedicated radio hardware, since every radio function can be handled and controlled digitally. With SDR Touch, you can receive and process live signals using nothing more than an SDR USB device and a suitable antenna.
Simply plug your SDR USB device into your phone or tablet using USB On-the-Go (OTG), open the app, and select a frequency to start detecting signals.
