Personalized wind-down coach

Fall asleep faster
when your brain won't shut up.

The gap nobody is building for

The habits exist.
The system doesn't.

Warm baths, dim lights, no screens, melatonin — these are all real tools. Some of them might work for you. But without a system to test them, you're just guessing every night.

01
No screen rule before bedtime
Good habit. But done randomly, there's no way to know if it is actually helping.
02
Melatonin
Maybe effective. But the timing, the dose, and how your body responds? Pure guesswork.
03
White noise
Right for some brains. Wrong for others. No feedback loop to know which you are.
04
Sleep trackers
Tell you how you slept. Never tell you why — or what single thing to change tonight.
05
Generic sleep hygiene advice
Designed for everyone. Which means it's optimized for no one, including you.
Lull is the system around the habits.

It builds your bedtime routine, tests one variable at a time, and uses your real sleep data to figure out what actually works for your body. Not a prescription. A process you own.

What early testers are saying

Real people, real sleep wins

How Lull works

Four pieces. One ritual.

01 · Setup

Build your routine in 3 minutes

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.

02 · Nightly

Walk through, one step at a time

Each step fills the screen. No back button, no navigation, nothing auto-advances. Optional spoken prompts for eyes-closed use.

03 · Wind-down

Pick the variables worth testing

Lights, temperature, warm shower, last caffeine, screens, wind-down method. Add what's relevant, skip what isn't. Order them however works.

04 · Improve

One variable, five nights, repeat

Morning rating correlates with what you did. Each evening, one concrete suggestion — never two at once. If it works, it becomes default.

Who it's for

Not a demographic. An experience.

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.

Fragmented sleepers

Sleep happens in windows.

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.

In Lull: mid-sleep mode, sepia widget, 15-min get-up prompt.
Cognitive over-activators

The brain didn't get the memo.

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.

In Lull: brain dump, then boring story. One-directional.
General poor sleepers

Tired, in bed, wide awake.

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.

In Lull: the improvement loop, finding your variable.
The one-variable loop

Behavioural correlation.
Yours, not a dataset.

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.

Log Do Rate Adjust
N≥5

Minimum five data points

No premature conclusions. Lull waits until a real pattern exists before it opens its mouth.

x1

One suggestion per evening

"Tonight, try dimming lights 60 minutes before bed." Never two at once. Never a checklist.

5n

Runs five nights before verdict

If sleep quality rises, the variable becomes a default in your routine. If not, it moves on.

~

Never prescribes

Every technique is a hypothesis — including CBT-I get-up prompts. Your body gets the final say.

Questions

Things people ask before 2am.

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

No. Meditation requires active focus — the opposite of what an over-activated brain needs at 2am. Lull's techniques are passive. Brain dump is one-directional. Boring stories go nowhere on purpose. 4-7-8 breathing has a single pulsing dot and a calm voice.
No — deliberately. Lull correlates what you did (lights, temperature, wind-down method, get-up prompt) with how you rated sleep the next morning. Behavioural, not biometric. Upstream of sleep, not downstream of it.
We don't know — and we say so. Every technique is presented as a hypothesis to test against your own data, not a prescription. The whole product is designed to find which variables move the needle for your body and brain.
If you want to continue, $6.99/month. If not, nothing happens — no card on file, nothing to cancel, no retention email cascade. We'd rather you leave than feel tricked.
CBT-I's stimulus-control technique is a first-line clinical recommendation for insomnia. But it isn't for everyone. If you have a condition affected by sleep loss, are pregnant, operate heavy machinery, or have a history of mania or seizures, talk to your doctor before using it. We show this at onboarding and in Settings.
Brain dump recordings and transcriptions stay on device. Routine and rating data sync via CloudKit (encrypted end-to-end on Apple's infrastructure) so you can move phones. No third-party analytics beyond privacy-first aggregate counts.
