FAQ

How is this different from Event Countdown Tracker?

Countdown Timer runs interval sessions from a duration you set, while Event Countdown Tracker counts down to a fixed future date/time.

Can I save my presets to my account?

Countdown presets are saved in your browser so they can be restored on the same device and browser.

Do I need a backend API key for this to work?

No. The timer runs entirely in the browser and settings are stored only in local browser storage.
