Worktrek — is an online implementation of a calendar where you mark whether the day was productive or not. By marking every day you will try to spend next day more efficiently. It is very simple, but like most of other simple things it works.

How does it work?

You just have to put a mark for yourself every day. It takes less than a minute and does not take much effort. Nothing motivates better than when you realize you have spent so many days idle.
