Information from meals logged throughout the day can be used to help generate nutritional advice, while data from workouts can be used to help set goals for the future. The Up app also allows users to log their sleep, which can be analyzed and used to provide advice on future sleep adjustments. All of the advice generated is powered by Jawbone's Insight Engine, which works with both recorded data and data from the Internet to deliver information on a variety of fitness-related subjects.
The app also includes a number of social functions, including the ability to add friends to a "team" to compare and track fitness scores and goals. Users can also set their own goals within a team and receive notifications when progress is being made. Insights generated by the Up app can also be shared through email, message, Facebook, and Twitter.
Up by Jawbone is a free app for the iPhone and can be downloaded in the App Store. [Direct Link]
