Common questions and troubleshooting
Can I rely on the countdown after closing the browser tab?
Keep the page open while using its display. Browser suspension, device sleep, or closing the tab can affect updates and alerts. Check the target date and local time before starting. Use a dedicated device alarm for medication, cooking safety, or another task where a missed alert could cause harm.
