Productivity Scientific GTD Timer starts with predefined time of two minutes by default and you can start countdown with one keystroke. Of course this does not mean that you can countdown only for two minutes - any reasonable time period may be used from seconds to hours.

Use case: Set time budget for any task
Time budgeting is a very popular time management technique, because time likes counting like money does. And even more, because you can get more money but you can't get more time - all people get the same amount of time each day - only 24 hours. That's why it is incredibly important to set a time budget for certain activities similar to process of setting money budget before making purchases.
GTD Timer helps to set time budget by limiting amount of time that you are planning to spend for a particular activity. Before starting anything, ask yourself how much time you are willing to invest in that activity. Launch GTD Timer with planned amount of time and stick to your time budget.
Use case: Watch time left to completion of some particular activity
GTD Timer can be used to display amount of time which is left before completion of some activity. You can use it as auction timer, presentation timer, kithen timer, display time left for rest break or working day. You can set time period to countdown or enter time when the activity ends using "T" prefix (see).
Use case: Personal reminder
GTD Timer is very suitable as personal reminder. When starting timer you may enter message to yourself and this message will pop-up when timer will finish coundown. You may start any number of timers simultaneously (available in registered version) with different reminders.
Using presets and commands you can automate reminders. For example, you can create reminder preset which opens Email client and use it when you create reminder to send letter for anybody (with "mailto" command). Using "net send" command you can create reminder which sends message for other people in local network.
Use case: Run commands at a specified time
Using presets with commands GTD Timer is exceptionally suitable to use as scheduler to run commands at a specified time. For example, you can create preset to shutdown a computer after some task finishes (as described in documentation).
You can use virtually any command: launch programs, run batch files or single commands and so on.
Use case: Access services with waiting queues impactfully
Many online services place users to waiting queue for some amount of time. For example, RapidShare file sharing service allows unlimited downloads only with RapidShare Premium Accounts, but if you use free account you have to wait for some amount of time between downloads. It is annoying to remember.
