Question 1

How is this different from the Pomodoro timer?

Accepted Answer

The Pomodoro tool follows a fixed 25/5 work-break cycle with session tracking. This Timer & Stopwatch is a plain countdown and stopwatch. No cycles, no breaks. Use it for test prep, lab experiments, presentations, workouts, cooking, or any task that needs a clean, distraction-free timer.

Question 2

Can I make the timer fullscreen?

Accepted Answer

Yes. Click the fullscreen button next to the controls. The display switches to a dark, distraction-free view with a giant time readout. Press Esc to exit. Works on desktop and mobile browsers that support the Fullscreen API.

Question 3

Does the dark mode reduce eye strain?

Accepted Answer

The fullscreen running screen uses a dark background so light from your screen doesn't compete with your work environment. It's especially helpful in low-light study sessions, evening workouts, or late-night work.

Question 4

Will it keep running if I switch tabs or the screen sleeps?

Accepted Answer

Yes. While the timer is running the tool asks the browser to keep your screen on (Wake Lock API, works on Chrome, Edge, Safari 16.4+, and most modern browsers). If you do switch tabs, the timer is anchored to your device clock instead of a ticking counter, so the elapsed and remaining time stay correct when you return, even after a long gap.

Question 5

Does it work offline?

Accepted Answer

Once the page loads, the timer runs entirely in your browser. No internet connection is needed to use it. Your settings are saved locally in your browser.

Question 6

Can I use this on my phone?

Accepted Answer

Yes. It's mobile-friendly. While the timer is running the tool holds a screen wake lock so your phone won't dim or sleep on you. For workouts or labs, fullscreen mode prevents accidental taps from interfering with the timer.
