Here is a tool that could help with productivity. It applies in a very simple way the Pomodoro Technique.
Work as hard as you can (get your shit done!) for 25 minutes, then take a small break during 5 minutes.
Right now there is no interaction possible, but in the future, you could be able to enter what you plan to do during pomodoris, then have a daily report.
Inspired by Xowap/talk-to-me. Some code reused from BrunoCartier/circles-clock.
