FAQ

Does the timer keep running in background tabs?
It updates every second while active, but browser tab throttling may reduce update frequency in inactive tabs.
Can I count elapsed time after the target passes?
Yes. Enable count-up after expiry to switch from remaining time to elapsed time.
Is this synced to a server clock?
No. It uses your local browser clock.
