TwinsTracker

A baby tracker built for twins and multiples — not adapted for them. One tap starts sleep or a feed for both babies at the same time, and each baby can be stopped separately, because twins never wake up together. Breastfeeding with side memory per baby, bottles, pumping with a milk stash, one-tap diapers, weight log and a 24-hour overview for up to four children — twins, siblings, or a nanny with several kids. Optional sharing keeps the whole household in sync — one purchase covers everyone. In English, Dutch, Czech and German. Not in the App Store or Google Play — it opens in the browser and installs to the home screen like a regular app. Works offline, without an account.

What TwinsTracker does

• Tandem tracking: one tap starts sleep or a feed for both twins with the same start time, and each baby is stopped separately. How tandem breastfeeding works in the app.
• Breastfeeding side memory per baby: the app suggests the opposite breast next time, and in tandem each twin gets their own side.
• Bottles, pumping and milk stash: time and amount for one child or several at once, fridge, freezer and deep freeze with expiry dates.
• One-tap diapers and a weight log: wet, dirty or both, plus date and grams with the gain since last time.
• Sleep with age-based wake windows: who is asleep, who has been awake too long, and a weekly sleep rhythm.
• One 24-hour overview for up to four children, each with their own color.
• Household sharing: a partner, grandparent or babysitter enters the invite code and sees the same data. One purchase covers everyone.

Questions parents of twins ask

How do I track breastfeeding twins at the same time?

Open Feeding, tap the second twin in the tandem picker and press start once. Both feeds share the same start time. When one baby unlatches, stop only that baby; the other timer keeps running.

Is there a baby tracker for twins without a subscription?

Yes. TwinsTracker is a one-time purchase through Gumroad. There is no subscription and no advertising, and one license covers the whole household.

Does it work for triplets or for twins plus an older sibling?

Yes. The app tracks up to four children side by side, each with their own color. Tandem is optional, so a single baby works too.

Is TwinsTracker in the App Store or on Google Play?

No. It opens in the browser at twinstracker.app and installs to the home screen like a regular app. It works offline and without an account.

Can my partner or nanny see the same log?

Yes. They sign in, enter the household invite code and see the same data on their own device, synced automatically. A second caregiver activates the app with the same license key and pays nothing.
