Track how often you weigh in with Beeminder

Beeminder is a tool for data nerds to commit to progress towards goals. You specify any graphable goal (these Applets assume you've created one) and Beeminder plots your progress. Keep your datapoints on the right side of the Bright Red Line or Beeminder will literally charge you money.
Tumblr is your canvas. Post text, photos, GIFs, videos, live videos, audio, anything. Applets can bring content to your Tumblr from all your different social medias, and help you manage your Tumblr likes.
