How to set an alarm

Select a time

The hour and minute selectors will be used to set a time. If you are using a 12-hour time, make sure to select either AM or PM. Above, you can see the current time, so you can check the alarm time you set.

Add a label (optional)

An alarm label is helpful for reminders. Common label examples are: Wake U,p Study Session, Call Reminder, Workout.

Select a sound.d

A sound can be chosen from the Sounds list to be your alarm. A sound can be selected, and then your device can be adjusted to the correct volume. There is one last thing you have to do before the alarm starts working. You must click "Start Alarm". Once you do this, the alarm will begin monitoring the time and play the sound when the desired time arrives.

Some of its key features include the following:

  • Real-time digital clock display: The time is currently displayed at the top of the webpage.
  • Works online, no login required: You don't have to create an account or download an app.
  • Use the sound test feature before activating your alarm to confirm the volume is loud enough, so you won't miss it if it's low or muted.
  • Use the alarm on mobile or desktop in modern browsers, so users feel flexible and in control wherever they are.
  • Accuracy and reliability: The alarm will sound at the time you set it. The time the alarm will be triggered is the same time that your device's internal clock will be set to. For normal personal use, the accuracy is reliable and consistent.
  • Does the time zone affect the alarm? No, it will still alarm at the set time.
  • To ensure your alarm sounds even when your device is in sleep mode, keep the browser open and check your device's power-saving settings, as some features may otherwise prevent alarms from sounding.
