I created a Google Gadget that helps you keep track of your Weight Watchers points throughout the day. It'll show up right on your Google home page, staring you in the face throughout the day, reminding you to keep track of your points.
I deliberately made this very simple. You add the points for your meal, snack, etc. and an optional note (as in a description of what you ate) and click "add" and it adds it to your daily total. It also includes a points calculator on another tab for your convenience and on yet another tab it includes a list of all the points you've entered for the day. When tomorrow arrives, you simple click "reset points".
To add it to you Google Home page, simply click on the "+Google" button on the lower left-hand corner of the Gadget below:
In case you are wondering about the technical details, the points are being stored to a database using Google's App Engine. Perhaps on another post, I'll discuss the code behind the Gadget on and on GAE.
