Fullscreen Countdown Timer | Simple HTML, No App, Focus Aid (Digital Download)

I made this because I needed a clean timer I could put on a screen and not think about.

Most timers work.
But they don’t stay open.

This one does.

-----

Core idea

Open it.
Set your time.
Leave it running.

No setup.
No distractions.

No apps. No login. Just open and start.

This is for you if

you need a timer you can see from a distance
you use a second screen or external monitor
you want something simple that just runs
you’ve tried apps and stopped using them
you don’t want notifications, accounts, or setup

classrooms
libraries
offices
presentations

Anywhere you need time visible without distraction.

Why this works

Most timers add more.

More controls
More features
More things to manage

This removes all of it.

You open it.
You see your time.
You let it run.

That’s why it works.
