Write down tasks and estimate how much time they’ll take. Edit or reorder tasks at any time.
Zonebox shows you small progress bar right under your Dock, so you can see how much time you have left.
To change the estimate, you can simply click plus/minus buttons next to the timer to add or substract a couple of minutes.
Need to focus on a book? Just enter the full-screen mode, and the only thing on your screen will be the Zonebox timer.
When your task is finished, Zonebox will alert you by changing color of the global bar, sound alert and a system notification.
