This tool is used to remember you to take some action in a time interval.

1 You can add a 'new timer' and configure it as you wish, or you can add a preconfigured timer like 'utamo vita' that will remember you each 3 minutes, 'conjure arrows' that will remember you each 10 minutes, etc...

2 Adjust the timer settings.

On a Timer panel, you can (in the respective order):
Configure the timer name on the textbox to the left,
Pause the timer,
Start/Continue the timer,
Reset the timer to the configured time,
Adjust the timer sound (language, volume, etc),
Adjust the timer time,
Remove/delete the timer.

3 Done! Start the timers that you want, and when the time runs out, the system will speak the timer's name.
