Alarm Clock
About the Alarm Clock
A dependable alarm clock is still one of the simplest ways to anchor a day, even when your phone is charging in another room or your work laptop is the only screen nearby. This browser alarm clock lets you stack multiple wake times with clear labels, pick a sound that actually gets your attention, and keep everything stored locally so your schedule survives a refresh. Parents use it for school-day wake-ups on a kitchen tablet, remote workers set a lunch-break chime at the desk, and students layer a study-block reminder beside an early class alarm. Unlike a single-purpose phone timer buried in notifications, the list view shows every active alarm at a glance so you are not guessing which toggle is still armed.
How to use it
- Open the alarm clock page and allow sound if your browser prompts for audio permission.
- Choose hour, minute, and AM or PM, then add an optional label that describes the purpose.
- Pick a sound from bell, digital, birds, ocean, or chime presets.
- Press Add to place the alarm in your list and confirm the toggle is enabled.
- Leave the tab open or install TimerClock as a PWA so the alarm can fire on time.
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.
