A browser countdown can time an ordinary activity, but it cannot track mood cycles, identify a health condition, or recommend a daily schedule for bipolar disorder.

A practical way to use the display

Use the timer only for a chosen task duration, such as reading a section of a book. You can change that duration or stop at any point. Decisions about symptoms, sleep and treatment need separate professional guidance.

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.
