What fits into a 1 hour timer?
One hour works best when the goal is already clear. Prepare what you need, silence interruptions, and use the visible sand as a gentle boundary for sustained work or study.
- A deep work or creative session
- A study block, exam, or practice test

How this visual sand timer helps
A visible sand clock makes the remaining time easy to understand at a glance. Use it when a normal countdown feels too abstract or when you want a calm boundary around one activity.
What is a sandtimer?
A sandtimer, also called a sand timer, sandclock, sand clock, or digital hourglass, shows time as a falling stream instead of a plain number. That makes a short countdown easier to feel at a glance.
When should you use this sand clock?
Use this online sandtimer for reading sprints, revision blocks, inbox cleanup, breathing breaks, or one task you want to finish before switching context.
When is Pomodoro a better fit?
If you want guided work and break rounds on repeat, move to the Pomodoro timer. It is a better fit when you want structure, not just one visual countdown.
When should you switch to Sandtime.io?
Switch to Sandtime.io when you need saved hours, project tracking, timesheets, reports, invoice-ready exports, or a shared view for your team and clients.

The timer stays intentionally simple. There is nothing to install, no account to create, and no settings screen to work through.

Online sand timer questions
Quick answers about this free browser-based sand clock and its preset links.
Is this online sand timer free?
Yes. Every duration works for free in your browser, with no sign-up, installation, or payment required.
Can I bookmark a specific timer duration?
Yes. Bookmark any ready-to-use timer below. The selected countdown will be ready when you return.
Does the timer keep accurate time in a background tab?
Yes. The display may refresh less often when a browser tab is in the background, but the timer calculates elapsed time from the clock and catches up when the tab becomes active again.
When should I use Pomodoro instead?
Use this sand timer for one visible countdown. Choose the Pomodoro timer when you want repeating work and break rounds with a more structured rhythm.
Need to keep the hours after the countdown ends?
This sand clock is useful when you want one visible focus block. Sandtime.io is better when you need project time tracking, timesheets, reports, invoice-ready exports, and a shared record you can keep after the timer ends.
