This is a simple tool for tracking time, different from other productivity and focus-oriented apps. It forces the categorization of time into two main types: SaveTime & KillTime.
You can allocate any task into these two categories based on your own experience and understanding.
Ultimately, your 'time deposit' balance is the difference between SaveTime and KillTime. Please take good care of your 'wallet'.
