Previously we posted about the new RFAnalyzer Android app for the HackRF which has a RF spectrum and waterfall display. Now RFAnalyzer is available on the Google Play store with experimental support for the RTL-SDR dongle. The app also now supports AM and FM audio demodulation.
The app is fully open source and the code and APK can be downloaded for free from its Git repository. Alternatively, the app can be downloaded from the Google Play store at a small cost of $0.99 USD.
To use the app you’ll need a USB OTG cable to connect your HackRF or RTL-SDR to your Android phone. More information on the app can be found on the authors blog.
An alternative Android app to RFAnalyzer is SDR Touch.
