This is an app for The Pomodoro Technique®. It tries to strictly follow the rules of The Pomodoro Technique®.
This is NOT a GTD replacement tool. You should still keep everything in your GTD tool like:
If pomodoro rings you'll earn a pomodoro completed sign next to your task.
During internal and external interruptions, you'll add items to your Unplanned & Urgent list. At the end of the day, you should move the remaining to your GTD system. Remember: You should keep everything in one place when using GTD.
I'm breaking only one rule here: I'm not maintaining an Activity Inventory. You should keep that in your GTD tool of choice. You should only store your daily items here. After every day, the remainder items should be moved to your GTD system.
Clicking on either of the buttons will create a new entry into the Unplanned & Urgent table and also create an internal or external sign next to your current task.
