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. Quick presets cover common hours like six, seven, and eight in the morning, while manual hour and minute selectors handle odd times such as 6:45 for a bus connection or 2:15 for a post-lunch meeting. Sound choices range from a classic bell to softer birds or ocean tones when you want less shock at dawn. Because alarms live in browser storage, you can return tomorrow without re-entering the whole week, though keeping the tab open or installing the site as a PWA improves reliability when the computer sleeps. Treat labels seriously: write "stretch before email" instead of "Alarm 3" so future you.
How to Use
- 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.

Troubleshooting the Alarm Clock
- No sound: Allow audio for this site, unmute the tab, and raise system volume. Some browsers block sound until you interact with the page.
- Timer seems paused in another tab: Keep the Alarm Clock tab visible for critical sessions, or install TimerClock as a PWA for better background behavior.
- Wrong time shown: Check the device clock and timezone. World and countdown tools also depend on the target zone you selected.
- Settings disappeared: Preferences are stored locally in this browser. Clearing site data removes saved alarms, themes, and recent durations.
- Alarm did not fire: Browser alarms need an open tab or installed PWA. Do not rely on them alone for medical or safety-critical wake-ups.
