Frequently Asked Questions
Will the timer work be functional if I close the browser or put my device to sleep?
No. The timer works only while the page is open and the browser is active. You can keep it in the background tab, and it will continue.
What are the difference between Duration and Target date and time?
Duration runs for a fixed time that you enter. Using your current time zone, target date and time counts down to a specific moment. If the moment has already passed, it indicates how long ago it was.
Is it possible to use my own sounds?
A direct link can be pasted to an audio file such as MP3, M4A, or WAV. Besides, it is possible to upload a file from your device. When audio is uploaded, it is played instead of being sent to the server.
What is the best way to share my timer with someone?
In this case, you should first open Edit, then click Copy link, and share the link. As soon as someone opens it, the timer loads with your settings. when uploading, the link uses a preset sound for privacy.
Can it be used on mobile phones?
Yes. It works on most modern mobile phone browsers. Keep the countdown tab open and make sure the sound is not muted.
Is it possible to loop the alarm until I stop it?
Yes. Select ‘Loop’ until stopped in the finish behaviour. If you want a single alert, select 'Play once'.
Is it possible to run more than one timer at same time?
Yes. Open separate tabs or windows to run multiple timers. So, you can create and share separate links for each timer.
