Yoyo Baby: Nap & Feed Tracker

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.
