Preset alarm

This preset page selects 6:45 AM so you can set the alarm faster. It's helpful for repeat schedules and for sharing a link that opens with the right time already chosen.

Once the alarm is active, keep the tab open for best reliability. When the target time arrives, you'll see an on-screen alert and hear the selected sound if your browser allows it.

Sleep-cycle suggestion

Sleep-cycle suggestion (optional): if you’re using 6:45 AM as a wake-up alarm, many people feel better waking between ~90‑minute sleep cycles. A simple guideline is to allow ~15 minutes to fall asleep, then aim for 4–6 full cycles. For 6:45 AM, example lights‑out times are: 9:30 PM (night before), 11:00 PM (night before), 12:30 AM.

Time zone and reliability note

Time zone reminder: alarms depend on your browser and device rules. If you travel or daylight saving time changes, confirm your device time zone is correct before relying on a browser alarm.

Morning routine suggestion

A simple routine helps the alarm do its job without relying on willpower:

  • Put the phone across the room so you stand up to stop the alarm.
  • Open blinds or step into bright light for 1–2 minutes.
  • Do a quick warm-up: 10 air squats + a short walk to fully wake up.
