What is online timer?

Online timer is web tool, which is used for tracking some time interval. We don't need any special device or any special software (application) installed in your computer or notebook, we need only access to the internet and web browser. We don't have allways mobile phone with us or it is not allways allowed to use it, and installation of some applications is not very practical way how to find the quick or best solution. Our online timer can track seconds, minutes or hours. When is the time, the sound alarm starts and the message appears, so we know that chosen time period already expired.

We can use this countdown timer during many 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... The possibilities are endless.

  • In order to make proper use of the timer your computer must be kept running and the browser's tab must not be closed
  • Some mobile devices (e.g Safari or iPhone) are blocking audio when browser is in background mode or when device is locked.

Tips for online timer

  • Timer's settings are binded to specific time and when some online timer starts, it's settings are automatically saved for chosen time period. List of all saved settings is in the section 'Saved timers'. Timers which we don't need anymore, we can remove.
  • Every timer has its own web url. If we save the link to the specific timer (e.g. in bookmarks), our timer with its settings will be accessible just with one click.
  • Every timer has its own url, so one browser tab can have only one active timer. If we want to have more active timers, we could use other browser tabs with different urls.
