About OneTask

OneTask is a new way to get things done :
Focus on one task at a time, Stick to it or just skip to the next task.
Be more efficient and relaxed !

Unlike other task management software, OneTask does not rely on priorities or deadlines to sort your tasks.
When you create a task, you have the choice to begin it now or later.
If you feel that a specific task should be postponed, skip it and pick a delay that fits the best.
This task will then only be shown to you again when this delay has passed.


  • Always on top
  • Automatically hide and show
  • 7 different layouts


  • Shows only relevant tasks
  • Loose deadlines : do it ASAP or leave it for later


  • Sound and visual Notifications
  • Send a mail to add a task
