stickK is a free web-based service created by behavioral economists at Yale University to help people accomplish their goals. No matter what your goal is - losing weight, quitting smoking, watching less TV or exercising more often - stickK can help you achieve it.

As mentioned in:
- Wall Street Journal
- New York Times
- Harvard Business Review
- The Economist
- Forbes
- ABC, NBC, BBC, Fox Business
... and many more!

By creating a Commitment Contract, you put your goal in writing, set a deadline, and give yourself additional incentives to achieve it.

You are up to 3x more likely to achieve a goal if you put money on the line. stickK allows you to bet on yourself (it's optional)--and if you're unsuccessful at your goal, we'll donate your money to charity, a friend, or even an organization you oppose!

Add extra accountability, by asking a friend or family member to be your Referee and verify your reports on your goal. Then invite friends to be your Supporters, and we'll send them weekly updates on your progress.

=== How it works ===

1) Create a Commitment Contract on the stickK.com website
2) Submit your Reports on the go using the stickK app.

=== stickK's Numbers ===

Over $23 million dollars on the line
Over 290 thousand commitments created
Over 750 thousand workouts completed
Over 13 million cigarettes not smoked

Cool concept but too many bugs


At first I thought this sounded like a good idea. Something that would encourage me to stick with my plan to meet my goals sounded wonderful. So I signed up. Two goals. This app doesn't work properly. Actually the Stickk website has issues too. Right off the bat, I didn't get any reminder emails to update my reports. The website didn't remind me, nor did the app notify me if I had a report due. I contacted them and was taken through a series of checks to see if I had everything set up correctly. I did. So I ended up setting my own reminders in my iCal so I wouldn't forget to submit my reports. The only email reminders I got were AFTER I submitted my report...at that point it would remind me. And I NEVER got reminders from the app either. I don't have much patience for such a buggy system. I mean, seriously, aren't the Stickk people responsible for making sure their system works??? I never missed a report so I didn't lose any money, but I was very put off by the problems. I won't be doing this again.
