"While Google still remains the king of search, there seems to be a movement towards providing answers rather than web page results. We've seen Microsoft offer Bing - some Verizon Android users are more than aware - which they market as a "decision engine."...If you're looking for answers to objective questions, Wolfram Alpha can give you the answer. It's now available for your Android."
Search for answers on your phone with Wolfram Alpha, now available for Android. Wolfram Alpha is a great application to have because it will give you answers for free on a wide range of subjects. But keep in mind that it works best with math, science and time/date-based questions and will provide only "fast facts" on other subjects. Meaning, you probably won't win any trivia contests with Wolfram Alpha, but it will tell you how many more days until your vacation!
