The Lazy meter website. Put your to do list on it, check them off as you do them, find out how much you actually do.

The LazyMeter is an online tool that helps you keep track of your daily tasks. It keeps you organized, so you can enjoy being lazy when you've completed all your tasks!
I've often recommended that you keep a daily task list, which requires you to write all your daily tasks on a piece of paper and move any unfinished tasks to the next day's list. The LazyMeter is basically the same tool, for techies.
There's a nice little video that shows you how to use this easy tool. Basically, you create every assignment or task that you need to complete and add any notes or reminders as needed. Then you check off tasks, one by one, as you complete them.
The best thing about a tool like this is that it lets you really enjoy your free time. Once you finish all your tasks and check them off, you can relax and know that you're right on schedule. You can be free from lingering worries that lurk in the back of your mind when you're disorganized.
And another plus? You can access the LazyMeter through your phone's web browser. No excuses!
