Great application and display. Only two problems. I wish it would remember its last parameter setting. I've had my phone time out in the middle of watching for something. When I wake up my phone, even moments later, I find that the parameters have returned to the default settings. I wish I could toggle one or both marker lines on or off from the marker buttons on the top. Where to grab the marker line to change its frequency position is not clear. Quite often it moves the entire SPAN. I'm using a Samsung Note IV.
