Looking for a better reason to have that high powered phone on your hip? How about saving the world, or saving yourself?

The applications are designed to change people’s behavior for the better, said Sunny Consolvo, one of UbiFit’s creators. In a three-month field experiment, people using UbiFit with the background display kept up their workout routines over the winter holidays, a period when people typically slack off on exercise, while people without the display let their regimen slide.

The project is funded in part though a grant from the Intel Foundation.

How could your phone do more for you? Have you tried this app, or others like it? Have you created an application that makes innovative use of the iPhone or Android’s robust sensors? Join in to the conversation in the comments and add your photos and videos to the Make Flickr pool!
