UTimer is a Pomodoro clock. The technique uses a timer to break down work into intervals, traditionally 25 minutes in length, separated by short breaks. Each interval is known as a Pomodoro.
How To Use:

Once you started the timer go for the task that you have to complete. It can be related to your work or studies. There is NO PAUSE button, so Start the timer only when you are ready to do the job. When the work period is over, there will be a rest period. Use this period for meditation, checking social media or having light snacks, etc.

The work-rest period will come after one another automatically unless you stop the timer.
