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. Payment is charged to your Apple ID account at confirmation of purchase. The subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings.

It is 3 a.m., you are holding your baby with one hand, and only one question is on your mind: when did the last feed end? Lull keeps feeding tracking simple: choose left, right, or bottle, tap once to start, and tap again to stop. The home screen shows three things at a glance: how long since the last feed, when the next reminder is due, and which side is suggested next. DESIGNED FOR REAL NIGHTS • At a glance The ring shows how long since the last feed and how long until the next reminder. The app, widgets, Lock Screen, Dynamic Island, and Apple Watch all show the same reading. • Intervals count your way By default, intervals count from the end of the last feed, or you can switch to counting from the start. Edit or backfill a feed and the schedule updates automatically. • Reminders that wake you at night Choose alarms, notifications, or night alarms with daytime notifications. Alarms only work after you grant permission; system alarms can sound through Silent and Focus modes. If permission is not granted, Lull falls back to time-sensitive notifications. • Night dim red palette During night hours, the interface automatically switches to a low-brightness dim red palette so the screen is never harsh in the dark. • Lock Screen, Dynamic Island, and widgets With Lull Pro, view the timer and next reminder, and control your current session right from the Lock Screen, Dynamic Island, and widgets without opening the app. • Apple Watch Start and stop feeds directly on your watch, with Apple Watch complications showing how long it has been since the last feed at any time. • Twins stay separate Swipe left or right to switch between babies. Each baby keeps an independent feeding history and reminder schedule. • Pumping has its own space Log pumping separately from breastfeeding, with side and volume in mL or fl oz. • Fix mistakes anytime Edit start time, duration, side, and volume, or backfill the feed you forgot to start. • Quiet and distraction-free No ads, articles, or crowded parenting dashboards—only the information you actually need in the middle of the night. Basic breastfeeding and bottle tracking, the night palette, and Apple Watch are free. One purchase of Lull Pro unlocks reminders and system alarms, Lock Screen Live Activity and widgets, and pumping. Try Lull Pro free for 3 days with no automatic charge. No subscription, and no Lull account required. Records sync through your Apple Account to your private iCloud database. Lull includes no third-party advertising or analytics SDKs.
