Boost 411

Boost 411 is an app that lets you run searches for firms and people right from your Android. Just indicate your location (or the city you want to search the classifieds for) plus what sort of business establishment you're looking for and within seconds you'll have all the results.

Besides searching for companies and service providers, Boost 411 lets you find people. Again, just set which city you want to run the search for and type in the person or business name. You can also reverse-search telephone numbers to see who they belong to.
