Repeater Finder - Android App

I saw this article about a Repeater Finder Android App and got pretty excited. This would be nice for my beach trip that is coming up. Then I saw it was $4.99. I'm a real cheap skate when it comes to software that I'm not sure I really need - even for such a small amount. I should just do my homework before I go and, if I decide I must have it, I can always buy/download it on the fly. It does look pretty slick.
