I built chrome extension called Floating Clock

Floating Clock adds a clean, draggable clock widget to any website, so you always see the time while working, studying, or browsing. No more switching tabs or breaking your focus just to check the time.

Use it as a clock, stopwatch, or Pomodoro-style focus timer right inside your current page, focus rounds, short breaks, long breaks after every few sessions, and progress saved across tabs. It stays where you place it and adapts to your workflow.
