Chrome: Google Chrome extension SpeedDate adds events to your Google Calendar quickly ea
Once you've got it installed and grant permission to submit events to your Google Calendar via OAuth, SpeedDate is ready to serve. Click its icon in your Google Chrome browser actions area and you'll have the option of quick-adding an event to your Calendar or creating one using the date and time you've selected on the current Web page.
During my visit to TSN, for example, I noticed their coverage for the upcoming NHL entry draft listed. I highlighted the time slot for the draft, clicked SpeedDate > Add Event, and the time was automatically filled. The quick add feature works nicely as well -- got a luncheon tomorrow from 1pm-2pm with a client? Type it in just like that, and SpeedDate and Google Calendar will pencil it in for you.
If you count Google Calendar among your must-use web apps and you're browsing with Chrome, SpeedDate will be an extremely handy addition to your browser.

Simply click the box for each day you complete a task, and skip the days you don't—the app will tell you when you've been dropping the ball. Don't Break the Chain is a free download, works wherever Google Chrome Extensions do.
