It is both a time-management technique as well as the name of a desktop application that you can download from this webpage that helps you apply the time management technique.

No, in fact timeboxing is a very simple time-management technique that you can do without any software - the only requirement is that you need to be able to keep track of time. Having said that, a watch with a countdown function is really useful.

A simple timeboxing protocol is the following: Set the countdown of your watch to 25 minutes and start working on your highest prio task. Once the countdown reaches 0, set it to 5 minutes and take a break for that amount of time. Rinse-repeat until you run out of work or time in the day. During the work period do not give in to distractions like reading or answering e-Mails or chat messages or going for a coffee, instead use your breaks to do that.

It provides a couple of features that makes working with the timeboxing technique easier, like starting of a work or break timer with a single click, playing a notification sound after a timer completes and keeping track of the number of work timeboxes and break timers completed each day, which can be viewed in table or barchart.

At startup it does a check if an update is available, but all the data is stored locally.
