FAQ

A sleep cycle is a repeating pattern of lighter and deeper sleep stages. Many people feel better waking closer to the end of a cycle than mid-cycle. That's why some wake times feel "cleaner" than others.

Buffers are the real minutes that surround sleep: time to fall asleep, time to wake up, wind-down time, and get-ready time. They're optional, but they make plans more realistic.

No. Timing Sleep provides planning tools, not medical guidance. If you're dealing with chronic insomnia, sleep disorders, or safety-critical fatigue, consider speaking with a clinician.
