What is online timer?

Online timer is a web tool, which is used for tracking some time interval. Online timers don't require special devices or special software (timer 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 timer to track hours, minutes or seconds. When the time comes and the info message appears than the online timer starts ringing.

Online timer can be used for many different activities, e.g. when we need to track time and we want to see from some distance what is the current progress. We can use it e.g. during cooking, exercise, training, presentations, in the school as a teacher or during the learning as a student, in the work, in the office, when we want to remind some activities, e.g. how long we want to learn, after what time we want to call or write someone, in how many minutes we want to take a break or go to lunch, in how many hours we want to go home... It has unlimited possibilities.

How to set my timer

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


  • In order to make proper use of your timer 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 timer before you use it
  • SLEEP MODE - Our timer 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).

Tips for online timer

  • Online Timer's settings are binded to a specific time and when an online timer starts, it's settings are automatically saved for the chosen hour, minute or second. A list of all saved timer can be found in the "Saved timers" section. Timers which you don't need can be removed.
  • Every timer has its own web url. If we save the link to a specific timer (e.g. in bookmarks), the timer including settings will be accessible with just one click.
  • Each browser tab can only have one active timer or alarm. If we want more, we can use other browser’s tabs which have different urls.
