Frequently Asked Questions

A posture reminder timer is a free online tool that periodically alerts you to check and correct your sitting posture. It helps prevent slouching, back pain, and promotes spinal health during long desk hours.

Choose your preferred interval, press Start, and the timer counts down in the background. When time is up you’ll receive a sound alert and/or desktop notification reminding you to adjust your posture. The timer automatically resets and continues.

Experts suggest every 20–30 minutes. We default to 15 minutes to help you build the habit faster. You can adjust it to 30, 45, or any custom duration that fits your workflow.

Yes, it runs as long as the tab remains open. Some browsers may slightly throttle background timers, but the tool uses standard intervals optimized for reliable background usage.

Absolutely! The page is fully responsive and works on smartphones and tablets. Keep the browser open to receive posture alerts throughout your day.

For the best experience, please allow notifications when prompted. This lets the tool send you a visible alert even if the browser is minimized. You can still use the sound alert without notifications.
