welle.io uses the rtl-sdr driver from https://play.google.com/store/apps/details?id=marto.rtl_tcp_andro. Additionally you need a rtl-sdr USB dongle which has to be connected to your phone via an USB-OTG cable.
This app is very computation intensive. You need at least a 4 cores CPU with 1.3 GHz for using this app. Please note that welle.io is under heavy development.
