The smartphone has become a one-stop-shop for organizing our daily lives. We use it to find our way around, stay on schedule and keep in touch with friends, co-workers and clients. But skipping around through all those apps lacks efficiency and wastes time. That's why Tempo AI developed the Smart Calendar app. It helps combat confusion and increase productivity by centralizing all the necessary info into one place. The Tempo Smart Calendar handles scheduling duties with aplomb, but also offers an array of social insights about your contacts, quick navigational tools and even helps you dial into conference calls without digging for passcodes. In order to help one lucky Engadget reader achieve this level of organizational zen, the company has provided an iPhone 5s and and AirPort Express. Simply head to the Rafflecopter widget below for up to three chances at winning. With all these enterprise-level tools at hand, you'll be prepared for everything the world can throw at you and you won't even break a sweat.

Winner: congratulations to Tim L. of Harrison, NJ.
