Beeminder is a goal-tracking tool with teeth. Mind anything you can graph — weight, pushups, to-do tasks completed — by replying with data when Beeminder prompts you. Or connect with a service (like Fitbit) to report automatically. We plot your progress on a Yellow Brick Road to your goal. Keep all your data points on the road and Beeminder will always be free. Go off the road and you (literally) pay the price.
