Frequently Asked Questions

How does Focus Timer maintain accuracy in background tabs?

The timer engine calculates remaining time against high-resolution system timestamps rather than simple interval ticks, ensuring accurate countdowns even when browsers throttle background tabs.

Are timer settings preserved across browser restarts?

Yes. Your custom interval lengths, audio options, and theme preferences are saved directly into your local browser storage.

Does the timer include audio alerts?

Yes. Optional audio chimes notify you when intervals conclude, synthesized in real time using the browser Web Audio API.
