Working out has never been so sadistic.
The brainchild of iOS developer Grailr, Carrot Fit knows more than 2,000 phrases — some kind and some cruel — thanks to iOS 7's new text-to-speech capabilities. Users enter their current weight when they download the app, and are given rewards such as workout tips and cat facts if they shed pounds. If users gain weight back, however, the app gives them a tongue-lashing.

“Meatbags,” as the app refers to users, can set reminders to avoid missing a weigh-in, share their progress with friends and check their body mass index, among other features. Future updates of Carrot Fit will include features such as a six-minute workout and the ominous-sounding Deathmarch 5K, according to the product's description in the iTunes store.
Download the app, which costs $1.99, in the iTunes store — if you dare.
