Right away, the fact that it requires downloading and installing an app (which you then have to log in to) leaves it pretty far behind in the "better user experience" race vs a mobile website that just works. It's hard to catch up from that deficit.

I don't bother with the Yelp app anymore because I'm sick and tired of having to re-download and re-log in to every app (which can be painful since I don't reuse passwords) every time I wipe the OS or get a new phone. Unless it's an app that doesn't need login, or that I use very frequently, it's just not worth it. I don't use Yelp often enough to justify it.

And the Google Maps app has fine reviews with less taint of corporate meddling anyway.
