San Francisco is many things, but shy about it's caffeine addiction isn't one of them.
(Of course, the fact that the Blue Crow Media and Blue Bottle Coffee share a certain hue to their names shouldn't sway you -- though we're not sure it didn't sway them.)
Blue Crow has one other coffee app and it's based on London. Leveraging two such elegant cities is good marketing-by-association thinking.
The SF app gets a five-star rating (based on eight submissions), while London is sporting a five-star as well, but is offered for free. (Hey, what's up with that? Too difficult to work out the Euro conversion?)
We citydwellers will shell out 99 cents.
