Questions about the online alarm clock
How does the online alarm clock work?
Choose a time, press Start Alarm and keep the tab open. A sound plays at the set time until you stop it.
Will the alarm ring if my screen locks?
Some phones pause web pages when the screen locks. Keep the device awake and plugged in for long alarms.
