1. Input the amount of time you need on the left
2. Click "Add Interval"
3. Repeat until all of your intervals are on the right.
If you need to delete one, the white X on the right will do that.
Clicking on "Settings" will bring up three options:
- repeat will allow the timer to start the first interval after the last has finished.
- flash will make the screen flash when any interval finishes
- sound will make a ding sound when any interval finishes
