NightLog: Offline Baby Tracker

Welcome to NightLog, the offline-first baby tracker built for real parenting.

When you're managing a 3 AM feed, navigating rapid first-year milestones, or planning that big first birthday, you need an app that just works. NightLog is designed to be completely private, lightning-fast, and easy to use with just one hand. No mandatory accounts, no cloud sync delays, and no subscription paywalls trapping your data.

🌙 Built for the Night Shift

One-Handed UI: Every primary action is anchored to the bottom "thumb zone" of your screen. Log easily while holding your baby.

OLED Dark Mode: Pure black backgrounds with deep red accents protect your eyes (and your baby's sleep) during midnight logs.

Massive Tap Targets: Oversized buttons and bottom-sheet input menus mean no more frustrating miss-taps when you're exhausted.

📊 Comprehensive Baby Tracking

Feeding Log: Track breastfeeding (with timers and left/right side toggles), bottle feeding (formula or expressed milk), and the transition to solid foods.

Sleep Tracker: Monitor naps and overnight sleep with automatic duration calculations to understand your baby's wake windows.

Diaper & Potty: Log wet, dirty, or mixed diapers to ensure your baby is hydrated and healthy.

Health & Wellness: Track temperatures, vaccinations, baths, and specific symptoms (fever, fussy, cough, etc.).
