iOS: CARROT Fit is one of the goofier ways to coerce yourself into getting into shape. Today, it gets a lot of new features that makes it more useful.
The original CARROT Fit was mostly about weight tracking, but now the app is more about fitness in general. That includes CARROT's variation on the popular seven-minute workout, Seven Minutes in Hell, as well as a new tracker, workout calendar and a new profile page.
If you're looking for an app that will insult you in order help you lose weight, CARROT does it well.
