Breathe in
Ceramic sleep ring + a real coach
Not more data. Better nights.
Lull reads your sleep stages, skin temperature and breathing through the night. In the morning, a coach turns it into one small plan you can actually keep.
What keeps you up?
Pick one. We'll tell you what your first month looks like.

A ring you forget you're wearing.
Four grams of glazed ceramic. No screen, no buzz, no blue light at 3am. It charges on a pebble by the bed while you shower.

Sized to disappear
Eight sizes, a soft squared edge and no metal against skin. Most members stop noticing it by night three.

Seven nights a charge
Drop it on the pebble once a week. Forty minutes later it is full, and so is the battery.

A coach, not a chart
Every Monday, a named human reads your week and changes one thing. Just one. That's the method.

Mornings that work
Better sleep shows up at 7am first: steadier mood, easier runs, fewer second coffees.
Members report, after eight weeks
Less lying awake. More of the good stuff.

NoorSleep coach, 9 years
Your deep sleep jumped on the nights you stopped screens by 22:15. Let's keep that, and move your last coffee to before 13:00. Nothing else this week.
Deal. Even on Fridays?
Fridays get a pass. Kindness is part of the plan.

Morning check-inOne tap: how rested do you feel? Your coach weighs it more than any number.
Sleep debt is rising. And everyone is feeling it.

One ring. One coach. One change a week.
Most sleep advice fails because it asks for ten changes at once. We ask for one, then we check it worked.
