From the developer:
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.
The OneTask slim bar stays on top of your windows and reminds you the current task you should keep focus on.
It will provide automatically sound and visual notifications (Growl compatible).
Your data are saved in the Cloud - with strong data encryption - so you can access them from any location.
Be more efficient and relaxed !
