No alarm set.
⚠️ Keep this tab open and your device awake — a closed tab or sleeping device can't ring.
How it works
- Step 1 — Pick the alarm time, add an optional label, choose one of three built-in chimes (synthesized live — no audio files needed), set the snooze length, and optionally enable desktop notifications. Test the sound before you commit.
- Step 2 — Hit Set Alarm. The page counts down and rings at the exact time — snooze or dismiss from the ringing card. Keep the tab open and your device awake.
Everyday uses
- Mornings — a backup alarm that works on any computer.
- Naps — 20-minute power naps without oversleeping.
- Cooking — timers for the oven while you work at your desk.
- Meetings — a discreet reminder to wrap up on time.
Rule of thumb: browsers throttle background tabs — for critical wake-ups, keep this tab visible and your volume up.
