A carp is a fish, but it’s also a verb that describes the action of constantly complaining. You may or may not like fish, but no one likes complaining. Carp will help you stop complaining by challenging you for 21 straight days. All you have to do is download the app and let everyone you know what you’re up to. That way you’ll be held accountable. Each day you go without complaining, the counter will move up. If you find yourself complaining just a little bit, you’ll have to reset the counter and start all over. When the challenge is completed, you can share it via Facebook or Twitter. You can share your failures as well.
