Enter an event name and a target date/time, then press Track to start the live countdown shown as days, hours, minutes and seconds. Save adds it to your local list (stored in this browser only); click any saved event to load it, or the × to delete it. Once the moment has passed the display flips to how long ago it was. Counting uses your local timezone. The list is private to this device — nothing is uploaded.
