A timer can mark a work window for an exercise that has already been assigned. It cannot choose a CBT technique or enforce when a feeling or thought should end.

A practical way to use the display

Keep the exercise instructions separate from the timer. Enter the duration agreed for the task, pause for clarification when necessary, and review the result using those instructions rather than the countdown’s ending alone.

Open the timer

Use the free homework timer to set minutes and seconds, pause or stop, and choose the display and alarm settings. Keep the tab open and the device awake while timing.
