CARROT Fit is one of the goofier ways to coerce yourself into getting into shape, and it just got an update with a ton of new features that make it a lot 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. All in all, it's a more useful version of the app, and if you're looking for an app that'll insult you in order help you lose weight, CARROT does it well.
CARROT Fit is $2.99 in the iTunes App Store.
