Nursling

Breastfeeding Tracker · iPhone, Apple Watch & Android

One tap.
No timers. No fuss.

A breastfeeding tracker built for one moment: 3am, one hand free, a baby in the other arm. It answers the only two questions that matter — which breast comes next, and how long since the last one — and records a nursing in a single tap.

Free for your first 50 nurslings. A one-time unlock after that — never a subscription.

Private by design

The premise

A parent at 3am should not have to navigate, confirm, or decide.

Most baby apps are built for the daytime version of you — the one with two free hands, a clear head, and patience for a form. Nursling was scoped down until only the 3am version was left. Everything that asked you to think got cut: no session type picker, no confirmation sheet, no "which side?" question, because the app already knows.

What it does

Narrow on purpose.

One tap

The button is already on the right side.

Open Nursling and the breast that comes next is already marked. Tap it and you are tracking. No confirmation screen, no dialogs, nothing to dismiss.

  • Starts you on the breast you finished on last time
  • Switch sides mid-session and it still counts as one nursing
  • A distinct haptic for every action, so you can feel the confirmation

Built for night

A screen that will not wake anyone.

The active nursing screen goes dark, drops to one glyph and one timer, and puts Switch and Finish where a thumb already is. Dark from 9pm to 5am, even if the phone is in light mode.

  • Buttons big enough to hit without looking
  • Undo sits beside the timer, for the tap you did not mean
  • A Live Activity shows the current side, and ends the moment you finish

Bottles, too

Breast, bottle or both — one log.

Log a bottle of formula or expressed milk in a couple of taps. It sits in the same history and the same insights as every nursing, so the day reads as one timeline.

  • Amount optional, with quick picks and one-tap repeat of the last bottle
  • Formula, expressed or other
  • Counted alongside breastfeeding in history and insights

Insights

See the pattern, not a spreadsheet.

Week, month and all-time views answer the questions a parent actually asks: how many, how long, and whether the sides are staying balanced.

  • Time between nursings measured start to start — the number you want at a glance
  • Average duration and total time per period
  • Left versus right balance, so you notice a drift early

Private by design

The data never leaves the phone.

Nursling has no account, no server and no analytics. Sessions live in a local store and ride along in your encrypted device backup. Export to CSV whenever you like — that stays free forever.

  • No sign-up, no email, no cloud sync
  • No ads, no third-party SDKs, no tracking of any kind
  • A CSV export you own, free whether you buy or not
iPhone Duo

Unfold it, and the log sits beside the breasts.

On the inner display of iPhone Duo, Home and History stop taking turns: the next breast and the bottle on one side, the whole day's log on the other. Folded, it is the same one-tap phone it always was.

Anywhere

Track without opening the app.

The fastest interaction is the one that never reaches the app. Nursling ships the same intent to every surface iOS gives it, so a session starts wherever your hand already is.

Start a nursing straight from the widget, without opening the app.

Control Centre

Add the control and start one from a locked phone in a single swipe.

Action Button

Map it once, and the side you need is one squeeze away.

Siri & Shortcuts

Ask, and the session starts — your hands stay where they are.

Live Activity
