Create a clean, full-screen countdown or count-up timer you can share via link. Count down to a specific date and time, count up from a past event, set a duration-based countdown, or start a simple stopwatch. Add an optional title, customize text color and background, choose from five font families (Rubik, Inter, Outfit, Literata, Oswald), and adjust font weight. Optionally redirect to any URL when the countdown reaches zero — useful for product launches, event reveals, or meeting start pages. Copy the shareable link or open the timer in a dedicated full-screen view.
