Under the sea is the scene timerz was built around. Sun rays come down through the water, jellyfish pulse and drift up at different depths, a school of fish crosses the screen, a sea turtle passes by now and then, a seahorse bobs near the reef and two clownfish dart around in short runs. Bubbles rise and caustic light plays near the surface. The fish stay out of the center, so the clock is always readable.
Sounds that go with it
The scene loads ocean waves and a stream at low volume with a bit of brown noise underneath. Waves are synthesized with a slow swell that rises fast and falls slowly, between seven and twelve seconds per wave. If you prefer silence, press A to turn the mix off and keep the scene.
Using it as an aquarium
Switch to clock mode with C and press F for fullscreen. The toolbar hides after a few seconds and you get a live aquarium with the time in the corner of your day. Moving the mouse shifts the layers with a parallax effect.
Features at a glance
- Three timer modes
- Pomodoro with focus, short break and long break cycles; a free countdown; and a stopwatch. The timer derives everything from the clock, so it survives a reload and keeps counting while the tab is in the background.
- Eleven animated scenes
- Seven illustrated scenes rendered with WebGL (rainy window, fireplace, night library, under the sea, snowfall, city lights, shoreline) and four minimal animated gradients (dusk, ocean, ember, paper). Each scene loads a suggested sound mix.
- Ambient sound mixer
- Eleven tracks you can layer with individual volumes: rain, thunder, wind, fireplace, ocean waves, stream, birds, brown noise, pink noise, white noise and café chatter. All but the café are synthesized in the browser, so nothing is downloaded and they loop without seams; the café is a short CC0 field recording that loads only when you turn it on.
- Tasks and stats
- A simple task list with one active task shown under the timer. Each finished pomodoro counts on the active task. Stats show sessions and minutes for today, a day streak and the last seven days.
- Music
- YouTube playback inside the page with four preset stations (lofi hip hop, jazz piano, dark ambient, classical) or any link you paste.
- Notifications and tab alerts
- A chime when a phase ends, optional system notifications, and the remaining time shown in the browser tab title with a progress ring in the favicon. When a phase ends, the tab title blinks until you come back.
- Mini timer on top
- In Chrome and Edge on desktop, press P to pop the timer out into a small window that stays above your other apps, with the scene behind it and a play button. It keeps counting while you work anywhere else.
- Keyboard shortcuts
- Space to start or pause, R to reset, N for the next phase, C for clock mode, F for fullscreen, P for the mini timer, X to mute everything, and one key per panel.
- Installable and offline
- timerz is a progressive web app: install it on desktop or phone and it works without internet. While a timer runs, the screen stays on. Scenes and sounds are cached after the first visit.
- Private by design
- There is no account and no server. Settings, tasks and stats live in your browser. Music is the only feature that needs internet, because it plays through YouTube.
Questions
Does the scene use a lot of battery?
It is WebGL at a capped pixel ratio, and it pauses completely when the tab is hidden. On a laptop it is comparable to playing a muted video. The minimal scenes are lighter if you need to save battery.
Can I add more animals?
Not from the app yet. New sprites are added in updates; the seahorse and the clownfish came in the second week.
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.
