This app supports spyservers, great, only this app supports it. But is very unstable (v4.0.5, Redmi note 5, MIUI 10.3), many blue screens, settings sensitive to FFT & FPS & Smoothing (error write multiringbuffer) and many FCs. For NFM is in app only BW 25kHz, (12k5 is missing). Lower sample rate than 48k maybe helps reduce internet BW (300KB/s with 48k) Permission, why needs GPS and camera access?
★★★★★
It's got potential. I find it keeps on stopping while monitoring a signal. Found by accident tapping the frequency display, it will start again. But this happens too often. When working its great, better sound than SDR Touch. Won't purchase just yet.
★★★★★
App works fine as a spectrum analyzer. It occasionally loses connection with the RTL SDR after changing configuration but for the most part works as advertised. Hopefully the developer will add a log file function comprising RF frequency, time-stamp and signal-strength measurements soon. I am using it on a Samsung Note 8.
★★★★★
Good start.Missing some features but i hope the developers will add them.1)
there is no rf-gain select for the RTL-SDR 2)cannot find how to change
bandwidth 3)Direct sampling support 4) stereo support. I love the bookmarks
feature! Get a 5 star to continue improving
★★☆☆☆
Was very unstable on Airspy Spyserver when it ran at all, but has now stopped working completely. Says current version is too old, points back to home page, then Play Store with no newer version. Windows version seems to have disappeared as well.
★★☆☆☆
Far too many errors and blue screens, I can't even change mode before it throws a fit. No direct sampling mode available for the RTL-SDR even though the driver you use supports this. This should have the restrictions removed and be labelled as a Beta until the bugs are ironed out.
★★☆☆☆
Crashes as soon as I try to connect to my rtl_tcp service.
★★☆☆☆
Unfortunately error screen overrides everything with ringbuffer problem every second or two so makes it unusable... errors could be logged silently surely?
