Quick link: /timer/3min or /timer/#3min starts a 3 minute timer. You can also write 90s, 1h30m, 5:00, or just a number for minutes.

Bookmark a timer: add this to the end of the web address: #t=5:00&label=BREAK&scheme=amber&auto=1. With auto=1 the timer waits for your first space or click, then starts. Copy link in Setup makes this address for you. Your settings are saved on this computer. Nothing is sent anywhere. It works with no wifi.

The map behind the clock is hand-drawn by Arvindh Sundar (Put The Player First). Shadowdark mode loads Pirata One by Rodrigo Fuenzalida (SIL Open Font License) from Google Fonts. The torch flame is "Fire animation" by Alex Sapozhkov on LottieFiles (Lottie Simple License), played with lottie-web (MIT) from cdnjs. With no wifi you get a simple font and a simple flame. Shadowdark is a trademark of The Arcane Library. We are not connected to them.
