[amsat-bb] droid sat app

[WA6FWF]

Hi,
  been looking at different sat tracking apps cant seem to find a 
particular feature I want,  I looking for a app that can run in the 
background and then it will popup and alert me when a sat is about to 
AOS, I tend to get busy doing something  and then miss a pass, anyone 
seen a app that will do this?

Thanks 73
