What this one is for
- Clear repeating alarm
- Volume follows the device
- Stops on any key or tap
An alarm is only useful if you hear it. The default is a repeating triple tone chosen to carry through a wall, with a softer option for quiet rooms. It opens at 15:00; change that with the chips under the dial.

Questions people ask
Will the alarm sound if the tab is in the background?
In most browsers yes, provided the tab stays open and the device is not muted. Keeping the tab visible is the most reliable option on phones.
Does it work offline?
After your first visit, yes. The page is cached by your browser, so it opens and runs without a connection.
Is the timer with alarm really free?
Yes, for personal and commercial use, with no sign-up. Use it in classrooms, gyms and streams without asking.
