The button above opens timerz at 45:00 over the Fireplace scene. Press Space to start.

Forty five minutes is a school class, a long reading session, or a deep work block for tasks that take a while to load into your head, like writing or programming. Pair it with a 10 to 15 minute break.

For a block this long, turn on a steady sound like brown noise or a fireplace and hide the rest of the screen. The remaining time stays in the tab title, so you can check it without switching tabs.

## How to use it

1. Open the timer with the button at the top of this page. It starts paused at 45:00.
2. Press Space or the play button to start, and Space again to pause.
3. Turn on ambient sounds with A, or pick music from YouTube in the music panel.
4. When it ends, the chime plays and the tab title blinks until you come back. Press Space to run it again.

## Questions

### Is 45 minutes too long to focus?

Not for most people once they are into the task, and some kinds of work need it. If your attention drops before the end, go back to 25 or 30 minute blocks.

### Is timerz free?

Yes. Every scene, sound and feature is free, with no account and no ads. If it helps you, you can leave a tip on Ko-fi, or become a supporter once (pay what you want, from 5 dollars, on Gumroad) to unlock your own photo as a scene and two extra fonts. There is no subscription.

### Does timerz work offline?

Yes. timerz is a progressive web app. After the first visit the app, its scenes and sounds are cached, and you can install it on your desktop or phone. Only the YouTube music needs internet.

### Where is my data stored?

In your browser, using localStorage. Settings, tasks and session history never leave your device. There is no server and nothing to sign up for. You can export your history as JSON or erase everything from settings.

### Does the timer keep running if I switch tabs?

Yes. The timer stores when it started and derives the remaining time from the clock, so a background tab, a sleeping laptop or a page reload do not make it drift. The remaining time also shows in the tab title.
