True Knowledge has developed a voice command app that promises to beat Apple's Siri in key areas. Evi on iOS (99 cents, App Store) and Android (free during beta, Android Market) can answer typical Siri quesitons, such as restaurant recommendations, but specializes in answering answering the less immediate questions that would normally have Siri perform a generic web search. A deep knowledge class system lets it answer age comparisons, provide recipes, and otherwise answer directly.
