My phone is littered with apps like these, which seem well designed to address a very specific problem which I don't have very often. The problem is remembering the app's there 3 or 6 or 9 or 18 months later when it would actually be useful to me.
I loath Waze. Its idea of shortcuts are terrible, its search routinely suggests things hundreds of mile away ahead of the match that's nearby, and sometimes I go through an area of intermittent service where it just decides to stop routing without giving a heads-up.
But Waze is so much better at accurately alerting me to police than my Valentine 1 was that I never even bothered mounting it in my latest car. Google supposedly integrates that data for years now but every time I try it comes up short. Google and Apple Maps are better in every other way, but for me at least, that one feature of Waze is a massive moat.
