You can look quite far ahead, it will always tell you when the next visible pass should be but you might want to tweak the settings so it only shows bright / visible events. I've found the weather forecasting to be mostly incorrect so it counts those as not visible (or visible when it's completely cloudy out there!)
I like it. I want to try and find a time to see it but notifications just before it happens don't work when I am asleep. Also, I thought I was mentioned on this, maybe he deleted it, but I am the nerdy wife on the couch in the original post. HI! I've been lurking around awhile but not posting so much.
I checked out your user page when I didn't recognise the name and saw you have lurked a while, but didn't know that :)! In the app you can add It to your calendar and from there have better control over when you get notified. We're going to see a comedian tonight and there should be a flyover just as we leave which will be cool.
