Sleep Cycle Sync

You think you know when to set your alarm?

Wake in the wrong 20 minutes and you'll feel it all day. Find the crest.

2–3 min Foundational Score /100

Sleep runs in ~90-minute cycles. Place your wake time inside a light-sleep crest — not a deep-sleep trough that leaves you groggy.

Educational only — not medical advice.
