Having a hard time finding them up there?
A time and a direction only gets you so far. Standing out in the yard, it is harder than it sounds to tell which point of light is the one you came out for. Flyby points your phone at it. Hold it up and the satellite is marked where it really is, moving, so you are watching the right bit of sky before it gets there.
It puts the orbit on a globe too, so you can see where it came from and where it goes next, and it wakes you for the good ones instead of leaving you to keep checking a list.
