Lull is a sleep experiment platform for the wired-but-tired. One variable at a time, tracked against how you actually slept, returned as a single suggestion each night.
Sleep is the output of decisions you made hours before you closed your eyes. Lull helps you figure out which decisions actually matter — for you.
No content to browse at bedtime. No choices to make. Your routine runs forward — one tap per step — and each morning a ten-second check-in teaches it what actually helped.
Six screens, max two taps each. No account creation blocking you. Outputs a starting routine + a default wind-down method chosen for your sleep problem.
Each step fills the screen. No back button, no navigation, nothing auto-advances. Optional spoken prompts for eyes-closed use.
Lights, temperature, warm shower, last caffeine, screens, wind-down method. Add what's relevant, skip what isn't. Order them however works.
Morning rating correlates with what you did. Each evening, one concrete suggestion — never two at once. If it works, it becomes default.
Your routine is built from three groups of variables. Pick what fits your life, order them however makes sense, and Lull learns which ones actually move your sleep quality.
Things in the room. Log once or get a timed reminder — "dim lights 60 minutes before bed," "warm shower 90 minutes before bed."
Things you did today. Quick taps. Correlated against sleep quality to find what matters for your body, not a dataset.
The cognitive-quieting piece. One method per routine, placed wherever you want. Also available one-tap in mid-sleep mode.
The gap between a body that's given up and a brain that won't. If that sentence describes your 2am, Lull was built for you — whatever put you there.
New parents. Shift workers. On-call professionals. Caregivers. The challenge isn't falling asleep once — it's falling asleep fast, and falling back asleep after waking at 3:14am with a full bladder and a loud mind.
Founders. Remote workers. ADHD brains. High performers who closed the laptop an hour ago and now lie in the dark with a running stack of ideas, anxieties, and half-finished sentences.
No specific life circumstance required. You've tried melatonin. You've tried meditation apps. You've concluded you're a bad sleeper. You're probably not — you just haven't found the variable that moves the needle for your body.
Lull is not a sleep tracker. No REM stages. No HRV. No smart alarm. Just: what did you do, how did you rate it, what's the pattern. Simple enough to trust.
No premature conclusions. Lull waits until a real pattern exists before it opens its mouth.
"Tonight, try dimming lights 60 minutes before bed." Never two at once. Never a checklist.
If sleep quality rises, the variable becomes a default in your routine. If not, it moves on.
Every technique is a hypothesis — including CBT-I get-up prompts. Your body gets the final say.

Still on the fence? The honest answer to most of these: try it for seven nights and see.
