Hourglass
3D focus timer
25:00
Ready when you are
Built for Focus, Not Dashboard Management
Hourglass combines a tactile sense of time with the accuracy and resilience of a modern browser timer.
Realistic Sand Flow Animation
Experience the soothing visual of digital sand flowing through our beautifully designed hourglass, creating a natural sense of time passing.
Flexible Focus Durations
Use a 5, 10, 25, 45, or 60-minute preset, or set any custom session from 1 to 180 minutes.
Accurate in Background Tabs
The countdown uses real timestamps, so switching tabs or refreshing the page does not introduce cumulative drift.
Optional Gentle Sound
Enable locally generated ambient audio and a completion chime when you want an audible cue without remote media.
Adaptive Rendering
Automatic quality controls, reduced-motion support, and a lightweight fallback keep the timer usable across devices.
A Focus Timer That Stays Out of the Way
Three simple steps turn an abstract countdown into a calm, visible focus ritual.
Choose Your Duration
Start with the classic 25-minute focus block, pick another preset, or enter a custom duration.
Watch the Sand Flow
Start the session and let the 3D sand make the remaining time visible without adding more information to manage.
Finish and Reset
When the sand runs out, the hourglass turns and is ready for another intentional session whenever you are.
Frequently Asked Questions
Everything you need to know before starting a focused session.
What is the Hourglass focus timer?
Hourglass is a browser-based focus timer built around a realistic 3D walnut hourglass. The visual sand makes elapsed time easier to feel while the countdown stays precise.
Can I use it as a Pomodoro timer?
Yes. Choose the 25-minute preset for a traditional Pomodoro focus block. The current timer is intentionally single-session, so it does not automatically schedule work and break cycles.
Can I customize the duration?
Yes. Presets cover 5, 10, 25, 45, and 60 minutes, and the custom control accepts any duration from 1 to 180 minutes.
Will the timer stay accurate if I switch tabs or refresh?
Yes. The countdown is based on absolute timestamps rather than accumulated interval ticks, and the active session is saved locally so it can recover after a refresh.
What happens if my device cannot render the 3D hourglass?
Hourglass detects WebGL support and rendering performance. When needed, it reduces scene quality or shows a lightweight hourglass fallback while preserving the countdown controls.
Do I need an account?
No. The timer works without sign-up, and session state, sound preference, and render-quality preference stay in your browser.
