Frequently asked questions
Does it ring on a phone with the screen locked?
It depends on the platform. On Android with Chrome, yes if the tab is open. On iPhone with Safari, not reliably, because iOS suspends background tabs. We recommend keeping the phone plugged in with the screen on if it is critical.
What is the best time to wake up in the morning?
The best time is the one that lets you sleep 7-9 hours and keep a constant schedule. For most people, 6:00 to 7:30 is a reasonable range if work starts at 8:00-9:00. More important than the exact hour is waking up at the same time every day.
How many hours of sleep do I need?
An adult needs between 7 and 9 hours of sleep. If you set the alarm at a fixed time, count backwards to know when to go to bed. For example, if it rings at 7:00, you should fall asleep between 10:00 PM and midnight.
