Ready — press Start when you are.

How it works
- Choose a comfortable interval between breaks.
- Start the timer while you work.
- When the countdown resets, stand, adjust posture, or stretch briefly.
FAQ
Does this send notifications?
Optionally. When you press Start it asks for browser notification permission; grant it and each reminder also shows a system notification. Without permission the on-page alert and sound still fire, as long as the tab stays open.
What interval should I use?
Built-in presets cover 20, 30, 45, and 60 minutes, or choose Custom for any interval from 1 to 240 minutes — pick whatever matches your work rhythm and comfort needs.
Can I choose what kind of reminder I get?
Yes. Pick Posture check, Stretch, Stand up, or Rest eyes, and the timer shows that reminder's own prompt message when it fires.
Does the timer keep running if I switch to another browser tab?
Yes, as long as the tab itself stays open. Switching to another tab is fine; closing the tab stops the timer, since everything runs in the page.
Is this medical advice?
No. It is a simple movement prompt, not medical guidance.
