For collecting as much data as possible (Step 1) about your time spent on your computer or mobile device, categorizing time spent (Step 2), and analyzing that data (Step 3), I highly recommend RescueTime (https://www.rescuetime.com/). I see that I have currently spent 16 hours and 51 minutes on steemit.com for the month of July, and I spend the most time on steemit.com during the 4 pm hour. Thanks for bringing my need for more effective time management to my attention!
