Siri – Personal Assistant for iPhone
Just like a real assistant, Siri understands what you say, accomplishes tasks for you and adapts to your preferences over time.
Today, Siri can help you find and plan things to do. You can ask Siri to find a romantic place for dinner, tell you what’s playing at a local jazz club or get tickets to a movie for Saturday night.
