Feeding
Two-tap bottle logging.
Log every feed in ml or oz without staring at the screen. Track volume, side, and timing so the next reminder lands at the right moment.
The baby tracker built for two parents on two phones.
Native Android, real-time partner sync, ad-free. Log every feed, sleep, and diaper from either phone — the other one's already up to speed.

The product, in four pillars
Everything a newborn day needs, nothing it doesn't.
Four things to track. Four screens that don't get in the way. The whole app fits the muscle memory of a half-asleep parent.
Sleep
Overnight sessions, handled.
Start a sleep timer with one tap and stop it when your baby wakes — even if that's the next morning. See nap patterns build over the week.
Diapers
Wet, dirty, or mixed.
Three taps and you're back to the changing table. Diaper counts feed into your pediatrician summary so you don't have to remember them.
Reports
Pediatrician-ready PDF.
Generate a clean, printable summary of feeds, sleep, and diapers in one tap. No watermark, no paywall — ready for your next check-up.
Partner sync
Two phones, one log. No shared password.
Each parent installs NextSip on their own Android phone and joins via a private invite code. Every feed, sleep, and diaper shows up on both timelines in real-time, with conflict detection if you both log the same thing half-asleep.
Free forever for two caregivers. PRO is a one-time purchase that unlocks 3+ caregivers for nannies and grandparents — no subscription.

Bypasses Do Not Disturb so you don't sleep through. Independent reminder volume — leave your ringer silent.
Smart reminders
A two-stage alarm tuned for newborn sleep.
A gentle pre-warning ten minutes before the next feed, then a main alarm at the exact time — based on the last log on either phone. Bypasses Do Not Disturb and runs on its own volume channel.
When your partner logs a feed, your alarm recalculates automatically. No coordination, no half-asleep math.

Is NextSip really free?
Yes. The free tier covers two caregivers, real-time sync, ad-free use, unlimited PDF exports, and offline mode — forever. NextSip PRO is a one-time purchase (never a subscription) that unlocks 3+ caregivers for families with nannies or grandparents in the rotation.
Do both parents need an Android phone?
Yes. NextSip is built natively for Android, so partner sync only works between Android phones. There's no iPhone version yet. The upside: the app stays fast and battery-friendly even at 3 a.m.
How does sharing the log between two phones work?
Each parent installs NextSip on their own phone with their own account — no shared logins. One parent generates a private invite code, the other types it in, and both phones share one real-time timeline. See how partner sync works →
What happens if I lose signal?
Logs save to your phone instantly, even offline. They sync to your partner's phone the moment you're back online, with background reconciliation every fifteen minutes so the timeline always matches.
Where is my data stored, and is it sold?
Your data is encrypted in transit and stored on cloud servers in an EU data center. We don't sell it, share it with advertisers, or use it for product analytics. You can wipe every byte from your account in Settings — one tap, no email confirmation needed.
One log. Two phones. Zero handover guesswork.
