LULLCYCLE
Wake up light, not mid-dream.
LullCycle finds tonight's best bedtime — timed to your ~90-minute sleep cycles, so your alarm lands between cycles instead of in the middle of a dream.
Three quiet steps to a better morning
Tell it when you wake
Set your alarm time — or when you want to fall asleep. One field, that's it.
It counts backward in cycles
LullCycle maps ~90-minute cycles plus your real fall-asleep time to find the windows that land between dreams.
Wake up on the edge of a cycle
You surface naturally instead of being torn out of deep sleep. Lighter mornings, same alarm.
