About Clockbeam

Clockbeam is a free set of browser tools for the time in front of you. Yuyu built it for a second screen, a projector, or a laptop you already have open.

What you can open

• The clock follows this device. Minimal, flip, analog, and scenic are the same time in different displays. Fullscreen is for a classroom or a second screen.
• The timer and the stopwatch wait until you press Start. The alarm shows the next real occurrence before you arm it.
• Pomodoro opens on a 25 minute focus block, then a short or long break.
• The world clock lists this device and the cities you add. Each row shows the local time, the date, and the current offset, including daylight saving.
• The meeting planner compares working hours in two to four cities and turns one chosen minute into each local time.

What the clock actually uses

The clock reads the time on your device. Your operating system is already keeping that clock in step with its own time source. Clockbeam does not add a second synchronization service, and it does not claim atomic-clock accuracy. City offsets come from the time zone data in your browser.

What is deliberately missing

There is no account, because a clock should not ask you to sign in. Saved clocks, focus lengths, and named setups stay in this browser. Export the JSON file if you want a copy you can move.

There is no promise that an alarm or a Pomodoro chime will play after you close the laptop. The tab has to stay open on an awake device. A phone alarm still wins for that job.
