20 Minute Timer FAQ
How long is a 20 minute timer?▾
1,200 seconds — twenty minutes. It is pre-set and sounds an alarm when it reaches zero.
Why is 20 minutes the ideal nap?▾
A roughly 20-minute nap keeps you in the lighter stages of sleep, so you wake feeling refreshed rather than groggy. Longer naps risk entering deep sleep and causing sleep inertia.
Should I set an alarm for a nap?▾
Yes. Setting a 20-minute alarm lets you relax fully without worrying about oversleeping, which is exactly what a pre-set countdown timer is for.
