Why to set alarm online?
Time management helps us set priorities and keep us focused despite the distractions all around us. As work demands and time pressure increase we need to manage our work better. Often there are times where our todo list is long and we prioritize one task and forget others. Time management has become a crucial skill for which alarm clocks can assist us in our daily lives.



What is an online alarm?

Online alarm clock is a web tool designed to alert an individual or group at a specified time. It is similar to an online countdown timer, but the difference is that online timers are used for time duration, whereas online alarms are used for specific times. Online alarm clocks don't require special devices or special software (alarm clock app) installed on your computer, notebook or mobile phone. We need only access to the internet and a web browser. We don't always have our mobile phones on us or we are not always allowed to use them and the installation of applications is not always the optimal solution. We can set an alarm clock for a specific time - hour and minute. When the time comes and the info message appears than the online alarm starts ringing.

Online alarm clock can be used for many different activities. Many people set alarm clocks when they go to sleep and want to wake up, however this is only one possible utility. We can also use it when:

  • we are at our computer and need to do something at a specific time
  • we want a reminder about an appointment or a priority on our todo list for example when we want to go to lunch or dinner, pick up children from school, go shopping, cook or bake something, go to the gym to train, do some sport or do our homework

We can use it at work, in the office, at school, at home or during outdoor activities. So Online Alarm Clock is not only a wake up alarm, it has unlimited possibilities.

How to set my alarm

  • Our first step is to set the alarm clock for a specific time, so we choose the appropriate hour and minute
  • Next we will see the alarm's settings screen on which every individual alarm has its own settings - ring tone and custom message. These settings are automatically saved when the alarm starts.
  • We can test the alarm by clicking on the button TEST ALARM. It is advisable to test the alarm before we use it, so we can see how or if it works, how it sounds, if the sound is enabled, if the internet connection is working and how the message is displayed.
  • Online alarm is then activated by clicking on the green button START ALARM
  • When we want to set a different alarm and select a different hour and minute, we can do this e.g. by clicking on the red button USE DIFFERENT ONLINE ALARM
  • When an alarm is active it looks similar to an online countdown timer, some information is displayed - the current time, the final time (hour and minute) and also the countdown or remaining time (hours, minutes, seconds), when the actual alarm starts.
  • When we want to cancel a current alarm we can click on the button STOP ALARM
  • One click on the settings icon shows or hides the alarm's settings
  • When the time comes your personalized message is displayed, the alarm starts ringing and then we can stop or snooze it


  • In order to make proper use of your alarm keep your computer running and your browser's tab open
  • Some mobile devices (e.g Safari or iPhone) block audio when the browser is in background mode or when the device is locked
  • To prevent problems with low or muted volume on your computer, we suggest you test the alarm before you use it
  • SLEEP MODE - Our alarm will not work if your computer is in sleep mode. We are not able to change your energy saver settings on your computer, but if the browser's tab with our alarm is active, then we can activate special techniques which prevent your computers from going into sleep mode. This feature might not work on all browsers/devices, but it should. To avoid potential problems related to sleep mode we suggest you disable the sleep mode functionality. Another solution is to keep the browser's tab with our alarm active, so you can see the content of our webpage on your monitor (it is enough in most cases).
