At first the app will seem slow, while downloading, while fetching info, while refreshing, etc. but thats besides the point... Its a great app for geeky space nerds just to find out where a certain satellites is, but trust me dont spend your time trying to find it because obviously they cant have many satellites to track because theres so many but if you just want to know where the ISS is, this is your app... Sometimes it may even fly over you within that 5 degree viewing area and you could just go outside and watch it streak across the dark night (hopefully clear) sky in less than 2 and a half minutes!
