One tap starts sleep or a feed for all your babies at the same time, and each one is stopped separately, because twins never wake up together. Works for any home with more than one little one: twins, siblings, or a nanny with several kids.

Most baby tracker apps are built for one child. With twins, you don't get one feed, you get two, often five minutes apart, and never quite at the same pace. One baby finishes and falls asleep, the other one is still going. A regular app forces you to track them as if they were one baby, or as two separate apps, and both quietly fall apart around 3 a.m.
TwinsTracker was built around one very specific twin problem: babies who start a feed or a nap at the same moment, but never finish at the same moment. One tap starts sleep or a feed for every child you pick, and each one gets its own stop button. No re-entering the start time for the second baby, no guessing whose timer is running.
It sounds like a small detail. In practice, it is the single biggest reason parents of twins give up on baby trackers within the first week, because none of them are actually built for two.
With one baby, remembering the last side is easy. With two babies feeding at different times of day, it isn't. TwinsTracker suggests the opposite breast next time, per baby, and in tandem mode each baby gets their own side tracked at once, with a tap to swap if needed.
Honestly, without gloss. TwinsTracker is an orientation aid for your babies' daily routine, sleep, feeding, diapers and weight. It does not diagnose anything and does not replace care from your pediatrician. If something worries you about a child's growth, sleep or feeding, that always belongs with your doctor first.
Tandem tracking was designed for twins, but the app works for any household with more than one little one: twins, triplets, close-in-age siblings, or a nanny watching several children at once. Up to four children are supported, each with their own color, switched with a swipe.
In thirty years of working with young children I have watched parents of twins arrive at the door running on almost no sleep, trying to remember which baby fed when. TwinsTracker grew out of exactly that: one honest tool built around the way twins actually feed and sleep, not a single-baby app with a second name field bolted on.

A tracker that starts with twins in mind, then quietly covers everything else a busy household needs.
Pick who is feeding or sleeping together, one tap starts a timer for every child chosen, and each one is stopped separately, whenever that baby is actually done. No other baby app does this.
Start and stop naps and night sleep per child, with a running timer so you always know exactly how long a baby has been down, or awake.
Breastfeeding remembers the last side per baby, bottles and pumping log time and amount for one child or several at once.
Wet, dirty or both, logged in one tap. The daily counter is exactly what the pediatrician asks about in the first weeks.
A partner, grandparent or babysitter signs in with the household invite code and sees the same data on their own device, synced automatically. One purchase covers everyone, a second caregiver activates the app with the same license key and pays nothing extra.
Just the date and grams, the app calculates the gain automatically. No percentiles, no judgement.
Every child on one timeline: who is asleep, who has been awake too long, plus daily bottle totals and a weekly sleep rhythm.
Real screens from the app, the same ones shown on Gumroad.
The whole app for up to four children, tandem sleep and feeding, milk stash, weight log and sharing with your household. No monthly fees.
