Comments on Spectrum SDR (RTL-SDR) for Android

★★★★★ Michael Santoro · Jun 14, 2026

Much better than those other apps with over a million downloads. I connect to my Raspberry Pi that runs rtl_tcp with an attached sdr dongle.

Once started you can't stop it! Reply was just exit the app, but I can't do that!
