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.
How long should a nap last?
Between 10 and 20 minutes is ideal to recover alertness without entering deep sleep. NASA recommends exactly 20 minutes. If you sleep more than 30 minutes, you wake up with sleep inertia and feel worse for a while.
What is a coffee nap?
You drink a coffee, set an alarm for 20 minutes, and nap. When the alarm rings, the caffeine is starting to take effect. It is the perfect combination: light sleep clears adenosine and caffeine blocks the remaining receptors.
