Yoyo Baby — Simple baby tracking with smart parenting tools.
Parenting is full-on. The last thing you need is a complicated app demanding two free hands. YoyoBaby was built for real life: log a feed, nap, or diaper change in seconds — with one thumb, while holding your baby.
And then it gets smarter. YoyoBaby comes with a growing set of smart tools designed to help you feel more prepared and less stressed — from predicting naps to checking if a food is safe for your baby.
--- ONE-HANDED LOGGING ---
Every screen is designed to be tapped quickly with a single hand. No buried menus, no multi-step forms. Just fast, simple logging that gets out of your way.
--- LOG WITHOUT UNLOCKING ---
YoyoBaby puts quick-log controls right on the Lock Screen. Start/stop a nap/sleep without ever opening the app — perfect for the middle of the night.
--- SMART TOOLS ---
Nap Prediction — After a few days of logging, YoyoBaby detects your baby's natural sleep windows and predicts upcoming nap times based on their own data — not generic schedules.
Milestone Checklist — Track your baby's developmental milestones with an age-appropriate checklist based on CDC guidelines. See what to expect at each stage, check off milestones as they happen, and know when to bring something up with your pediatrician.
Food Safety Lookup — Wondering if your baby can eat something? Search for a food and get clear, age-specific guidance instantly. Know what's safe, what needs prep, and what to avoid — so mealtime introductions feel less stressful.
Product Picks — Overwhelmed by baby gear? YoyoBaby curates top picks across strollers, car seats, monitors, bottles, and more — each rated using real editorial reviews. Skip the research rabbit hole and buy with confidence.
More tools are on the way.
--- SYNCS ACROSS YOUR DEVICES ---
YoyoBaby uses iCloud to keep your data in sync across all your iPhone and iPad devices automatically — no setup required.
--- PRIVATE BY DESIGN ---
Your baby's data is stored in your own iCloud account. No accounts required to get started — just open the app and begin.
--- ALWAYS FREE ---
YoyoBaby is free to use — all features, no paywalls, no subscriptions. We're building this alongside real parents, and keeping it free is part of the promise. Your feedback shapes what comes next.
Download YoyoBaby and start logging in under a minute.
