How to use Study Timer

Set the values you need, press Start, and keep this browser tab open. Most tools store only practical preferences locally in your browser.

Timer accuracy is based on timestamps, so the display corrects itself after tab backgrounding. Browser alarms and notifications still depend on browser permission, power state, and open-tab behavior.
