BabySync+
Log Baby from Lock Screen
Only for iPhone
Free · Designed for iPhone
iPhone
Log feedings, diapers, and sleep without even opening the app. Built for exhausted parents at 3 AM. No account required.
It's 3 AM. You're half asleep, holding a crying baby in one hand. The last thing you want is to unlock your phone, open an app, and navigate through menus just to log a feeding.
BabySync was built for this exact moment.
TAP THE WIDGET. DONE.
Record feedings, diapers, and sleep directly from your Home Screen widget — no need to unlock or open the app. One tap is all it takes.
- Bottle feeding: Tap to log instantly with smart amount memory
- Breastfeeding: Track left/right sides with independent timers
- Diapers: Log pee, poo, or both in a single tap
- Sleep: Start and stop the timer right from the widget
HANDS FULL? USE YOUR VOICE.
"Hey Siri, log bottle feeding BabySync."
When both hands are busy changing a diaper or soothing your baby, Siri does the logging for you. Three voice commands cover all your daily needs.
SEE IT ON YOUR LOCK SCREEN
Active timers appear in the Dynamic Island and on your Lock Screen. Glance at how long your baby has been sleeping without touching your phone.
DESIGNED FOR DARKNESS
The pure black interface isn't just aesthetic — it's functional. Minimal brightness means minimal disruption to your baby's sleep (and yours). Every button is placed in the thumb zone for single-hand use. Haptic feedback confirms each action so you don't need to look at the screen.
WHO GROWTH CHARTS
Track your baby's height and weight against official WHO percentile curves. See exactly where your child falls on the 3rd, 15th, 50th, 85th, and 97th percentile lines — perfect for pediatric checkups.
SMART FEEDING REMINDERS
Set a reminder interval (1-6 hours) and the widget shows a live countdown to the next feeding. When it's overdue, the widget turns red so you never miss a feed.
YOUR DATA STAYS YOURS
No account creation. No email. No servers collecting your baby's data. Everything syncs privately through your own iCloud — automatically, silently, securely.
WHAT YOU CAN TRACK
- Bottle feeding (ml with smart ±10ml adjustment)
- Breastfeeding (left/right side, duration with pause/resume)
- Diaper changes (pee/poo/both, with color and texture details)
- Sleep duration (real-time timer with background tracking)
- Growth records (weight, height with WHO percentile comparison)
- Daily summary (total milk, breastfeeding minutes, diaper counts)
- Complete history (edit, delete, review past entries)
BUILT NATIVELY FOR iPHONE
Not a cross-platform port. BabySync uses WidgetKit, ActivityKit, AppIntents, SwiftData, and CloudKit — every feature Apple built for a seamless iPhone experience.
Available in English, Japanese, Vietnamese, Simplified Chinese, and Traditional Chinese.
