Online Alarm
Tip: Install TimerClock as a PWA for reliable alarms when the tab is in the background.
About the Online Alarm
Online alarms solve the friction of locked-down machines: school Chromebooks, corporate laptops, library desktops, and borrowed tablets where app installs are impossible. Open a tab, allow sound once, set times, and you have wake and reminder capability without IT tickets. Travelers use hotel business centers for early departure backups; students in dorms rely on bedside laptops when phones charge in the hallway; caregivers open online alarms on clinic waiting-room kiosks for next-appointment cues. The trade is honesty - you must keep a tab available or install TimerClock as a PWA, because browsers are not magic background daemons on every OS.
How to use it
- Visit the online alarm page in a modern browser.
- Allow audio when prompted so alarms can ring.
- Add times with labels and sound presets.
- Keep tab open or install PWA for reliability.
- Bookmark the page for tomorrow on the same device.
Good to know
This alarm rings only while the browser is allowed to run the page. Sleep, a closed laptop, or a denied notification permission can silence it. Do not use it as the only alarm for medicine or anything safety-critical.
