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.
