Online timer guide

How to use an online timer well

Pick a preset for common tasks, then keep the browser tab open while the timer is running.

Use short timers for breaks, stretching, cooking, and classroom transitions
Use focus and Pomodoro timers for repeat work sessions
Use shareable timer links when a group needs the same setup

Browser timer reliability

ClockHub timers run locally in the browser, so they are free and private but still depend on the open page and device power state.

Keep the tab open until the countdown finishes
Keep the device awake for long timers or shared screens
Use a native alarm app for safety-critical wake-up alarms
