Most sleep apps hand you a number and walk away. Lull tells you why you slept the way you did — and what to change tonight. TRACKING THAT RUNS ITSELF Wear your watch to bed and you're done. Lull reads your nights from Apple Health — no timer to start, no button to press. You wake up and last night is already scored. A SLEEP SCORE THAT EXPLAINS ITSELF One number, 0 to 100, built on sleep science: duration, efficiency, restlessness, deep and REM sleep — every target adjusted for your age. Open any night to see where the points came from and where they went. FIND WHAT'S REALLY RUINING YOUR NIGHTS Coffee at 6pm. A late workout. Two glasses of wine. A warm shower. Log a habit in seconds and Lull lines it up against your real sleep data, night after night, until the pattern is impossible to miss. Not generic advice — your body, your tolerances. Learn what you get away with, and what quietly costs you an hour of deep sleep. FALL ASLEEP FASTER, STARTING TONIGHT Guided techniques you can run in bed: 4-7-8 breathing, the military method, the cognitive shuffle, the 20-minute rule and warm-shower timing. Lull keeps score of which ones actually work for you. AN AI COACH THAT KNOWS YOUR NUMBERS Ask why Tuesday fell apart, or what to do about a 3am wake-up. Your coach answers from your own scores, habits and trends — never from a generic script. FOUR WEEKS TO BETTER SLEEP A guided program built on CBT-I, the clinical gold standard for insomnia: tighten your sleep window, rebuild sleep pressure, then widen it again as your nights consolidate. PUT THE PHONE DOWN Pick apps to block during your wind-down window so your phone stops fighting your bedtime. Your choices never leave your device — Lull can't see which apps you picked. SEE THE WHOLE PICTURE Sleep debt, social jetlag, bedtime consistency and weekly trends, in plain language. Spot the factor that has been dragging your sleep down all month — and the habit that helps more than you thought. MORNING CHECK-IN A gentle prompt after you wake ties how you feel to how you slept, so your scores reflect real life and not just sensor data. AT A GLANCE Home Screen and Lock Screen widgets plus an Apple Watch complication keep last night's score one look away. PRIVATE BY DESIGN Your sleep data stays in Apple Health, on your device. The apps you pick for wind-down never leave it. LULL PRO Tracking and your nightly score are free. Pro unlocks the AI coach, full trends and analysis, the 4-week program and wind-down blocking: 3-day free trial, then $1.99/week.
