Baby Tracker & Newborn Log

NextSip is an offline-first baby tracker and shared newborn log built for co-parenting. Track breastfeeding, bottle, pumping, sleep, and diapers on one baby routine, kept in real-time sync between both parents. No ads. No shared logins.

Stop the 3 AM "when was the last feed?" guesswork. Log a feed in two taps and your partner sees it instantly, without either of you waking the other.

SHARED BABY TRACKER FOR DADS MOMS CAREGIVERS
Real-time family sync. Invite your partner, nanny, or grandparents with a private code, and everyone adds to the same newborn log.
Your own private account. Each parent signs in separately, so there is no password sharing and no single login passed between phones.
See who did what. Every entry shows who logged it on a shared activity feed.
Never double-logged. If two people record the same feed at once, NextSip spots it and merges the duplicate for you.
Works offline. Log anywhere, and your baby data syncs the moment you reconnect.
Most parents who install NextSip invite their partner within a day.

BABY ROUTINE TRACKER
Baby routine tracker. Feeds, sleep, and diapers build into one daily rhythm you can see.
One baby log. Every entry lands in a single continuous timeline, newest first.
Insights. Daily totals and patterns across feeds, sleep, and diapers.

FEEDING TRACKER (BREASTFEEDING & BOTTLE)
Breastfeeding tracker. Time each side and add your own nursing notes.
Bottle & formula tracker. Record expressed breast milk and formula amounts.
Feeding tracker at a glance. See how the day's feeds are going without opening a report.
One-tap logging. Long-press the app icon to jump straight to a new feed, no menus.

BABY SLEEP TRACKER
Baby sleep tracker. Log naps and night sleep, and watch the routine build day by day.
Sleep timer on your lock screen. One glance shows how long they've been asleep, no unlocking.

DIAPER & DAILY LOG
Diaper tracker. Record wet, dirty, or mixed changes, and log diaper color against a built-in color guide.
Weight updates. Add a new weight whenever you weigh them.
PDF reports. Export and share a clean, pediatrician-ready summary of feeds, diapers, and sleep (NextSip+).

NEWBORN TRACKER FOR MORE THAN ONE BABY
Switch babies in a tap. Manage more than one child from the profile header. Great for twins. (NextSip+)

VITAMINS & REMINDERS YOU CAN TRUST
Vitamin tracker. Log daily vitamins and mark them done from the reminder notification.
A soft pre-alarm before the next feed is due, then an on-time alarm with Snooze and "Already Done."
Alerts survive reboots, doze mode, and locked screens.

BUILT FOR CO-PARENTING
Coparenting works when both parents see the same picture. NextSip is a baby tracker for two phones and one baby. No handing a phone across the bed, no "did you write it down?", no shared password.
Built natively for Android, so it opens fast and stays out of your way at 3 AM.

If you want a simple baby tracker to replace the notes app or paper baby diary, and to get your partner logging too, NextSip is the shared newborn log for your whole care circle.

Free to use, with no ads. NextSip+ is a one-time purchase, yours for life, with no subscriptions.
