ZAZU Baby is built by a parent, for parents. If you ever need a hand, we've got you.

Built for Zoe and every baby

When our daughter Zoe was born, my partner and I were overjoyed — and completely overwhelmed. We had family around us, we had love in abundance, but what we didn't have was clarity. When should she eat? How much? Was this sleep normal? Every question led to another.

We tried the apps that were out there. They were powerful, but they felt like they were built for engineers, not exhausted new parents at 3am. Learning the app felt like a second job — on top of the hardest job we'd ever taken on.

So we built ZAZU Baby. Not as a product. As a necessity.

We built it in every moment she gave us — during naps, late nights, early mornings, stolen minutes between feeds. Zoe was our first user, our test subject, and our most honest critic. Every pattern the app got wrong, she showed us. Every assumption we made, she quietly broke. We'd notice something, research it, cross-check it against pediatric guidelines, and update it. Day after day, feed after feed. It was, in its own exhausted and beautiful way, the most we'd ever felt like we were doing something that truly mattered.

We wanted something that worked from day one — install it, enter Zoe's age, and let the app do the thinking. It suggests how much to feed, how often, and when the next feed is likely coming — first based on her age, then based on her own unique rhythm. Because no two babies are the same, and no app should pretend otherwise.

As Zoe grew, the app grew with her. New feeding quantities. Solid foods. Allergen introductions. Sleep patterns. And now, past her first birthday, it's shifting into toddler mode — still adapting, still learning, still one step ahead of us when we need it most.

There's also a daily notes section, where we've captured the little moments — her first laugh, a particularly chaotic dinner, a quiet Sunday morning. Every week, the app quietly turns those records into a small story — sometimes funny, sometimes tender, always completely hers. One day, Zoe will be able to read it all back. Her story.

And one day — so will yours.

Is ZAZU Baby free to use?
Yes. All daily tracking features — feeding, diapers, sleep logging — are completely free. Full Access is an optional one-time purchase that unlocks AI-powered smart feeding, allergen tracking, advanced insights, and two-parent CloudSync.
Can both parents use the app together?
Yes. Two-parent CloudSync is available with Full Access. It uses Apple CloudKit for real-time sync — no accounts or passwords needed. Both parents always see the same up-to-date data.
Does ZAZU Baby track sleep?
Yes — sleep tracking was added in version 2.0. You can log naps and night sleep, view Sleep Insights (total sleep, nap counts, bedtime trends), and compare against age-appropriate recommendations.
What is Full Access and how much does it cost?
Full Access is a one-time purchase (no subscription) that unlocks everything: Smart Feeding with on-device AI, night & evening pattern learning, allergen tracking with meal suggestions, advanced sleep and growth insights, PDF reports, and two-parent CloudSync. Pricing varies by region.
How does Smart Feeding work?
ZAZU Baby's on-device AI learns your baby's unique feeding pattern over time. It adapts to night and evening rhythms, adjusts as your baby grows through 12+ months, and sends a predictive reminder about 20 minutes before the likely next feed — so you're always one step ahead.
Can I manage multiple babies?
Yes. ZAZU Baby supports multiple baby profiles. Switch between them instantly from the main screen — all data stays completely separate per profile, and each syncs independently via CloudKit.
Is my baby's data safe?
Absolutely. ZAZU Baby collects no personal data. All information is stored locally on your device. If you use CloudSync, data is protected by Apple's encrypted CloudKit infrastructure. Apple has independently verified: Data Not Collected.
