Built for the feed when it is 3 a.m., one hand is free, and you can barely keep your eyes open. Lull keeps breastfeeding simple: choose left, right, or bottle, then tap once to start and once to stop. The home screen shows exactly how long it has been since the last feed ended. WHY PARENTS CHOOSE LULL • Clear feeding timer Intervals and reminders count from the end of the previous session—not the start. Edit or backfill a feed and the schedule updates with it. • A stronger night reminder Enable the system alarm for a reminder that can sound through Silent and Focus modes. If alarm permission is unavailable, Lull falls back to a time-sensitive notification. • Lock Screen and Live Activity With Lull Pro, follow the timer and use feeding controls without returning to the app. • Twins stay separate Swipe between baby profiles. Each baby keeps an independent feeding history and schedule. • Pumping has its own space Log pumping separately, including side and volume in mL or fl oz. • Fix what happened in real life Edit times, duration, side, and volume, or add the feed you forgot to start. • Calm after dark A focused, dark-first interface avoids charts, articles, ads, and noisy dashboards. Basic breastfeeding and bottle tracking is free. Try Lull Pro free for 3 days—there is no charge and nothing renews; when the trial ends, Pro features stop unless you buy. One purchase of Lull Pro unlocks scheduled reminders and system alarms, Lock Screen and Live Activity tracking, and pumping. No subscription, ads, or Lull account. Your records sync through your private iCloud account. Lull includes no third-party advertising or analytics SDK.
