FAQ

Is this online timer free?+

Yes — Chrono Timer on iautre.com is completely free, with no ads, no account and no sign-up. Themes, alarms, tasks and habits are included.

Will the alarm sound if the tab is in the background?+

The countdown keeps an absolute deadline, so it still finishes if the tab is hidden. Browsers throttle background timers, so the alarm can land up to about a minute late. Turn on notifications for a reliable on-screen alert — the native app schedules a system alarm instead.

Does the timer work offline?+

Yes. Chrono Timer is a Progressive Web App — after your first visit it works fully offline, and you can install it as a standalone app on desktop or mobile.

Can I use my own alarm sound?+

Yes. Besides the five built-in sounds, you can upload any MP3 or WAV file, control the volume, and set fade-in, fade-out and looping.

Can I customize how the timer looks?+

Everything is customizable: backgrounds (colors, gradients, images, video, particles), 13 clock styles, Google Fonts, glow and neon effects, and full color themes you can save, export and share.

Is my data private?+

Timer settings, themes, tasks, habits and uploaded assets stay in this browser (localStorage and IndexedDB) — there is no account and no analytics. If you pick a Google Font other than the two bundled with the app, the font file is fetched from Google’s servers.

Does Chrono include tasks and habits?+

Yes. Open Tasks and Habits from the top bar. Add priorities and due dates, track weekly habits with streaks, and keep everything offline with optional full backup.

Can I drag the timer on the screen?+

Yes. Grab the timer (or the Drag handle) and move it anywhere. Turn off Snap to Center in Layout settings for free positioning, or drag once to unlock automatically.
