Frequently asked questions
Does the alarm work if my computer sleeps?
No — if the device sleeps, the browser pauses. Keep it awake and plugged in, and the tab open.
Can I set an alarm for tomorrow?
Yes — if the time has already passed today, the alarm is set for the same time tomorrow.
How loud is it?
It uses your system volume. Press 'Test sound' first to check you can hear it.
