Questions & answers
How do I set a 15 minute timer?
It's already set! Just press Start. The countdown runs for 15 minutes and then rings.
Will it ring if my screen locks?
Keep this tab open with the sound on. The timer uses your device's clock, so it stays exact, and it asks the browser to keep the screen awake while running.
