I am using it for a long time and it is very accurate and very stable.

Best SDR app for a smartphone I have ever seen. I am very impressed. I used it today on my walk and listened to QSO's on 20m. Good job, keep up the good work !

I usually don't give negative reviews but this app has so many bugs that I thought I need to. Zooming doesn't work, some buttons don't work. In other words this application is unusable. I also can't find any help screens or manual. Have fun with my 10 bucks.
