This online tool counts down a duration. It does not design an exposure exercise, choose its length, or determine whether continuing an exercise is appropriate.

A practical way to use the display

If a clinician has included a timer in an existing plan, use the duration and stopping instructions from that plan rather than treating a preset as clinical advice. Check the sound setting beforehand; No Alarm provides a silent ending.

Open the timer

Use the free visual 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.
