Siri, as we know it, is pretty awesome. It is smart and understand the natural speech perfectly well. But it has it’s limitations. If you ask it a general knowledge question, it will seek your permission to go look it up on internet. Moreover, the results may be factually correct but Siri may not understand exactly what results you were looking for. How about a voice-app that can understand the kind of results you are looking for, go look it up on internet, cross-match the result and get you the exact answer? Evi, a new app for smartphones does just that!
