Android app for tracking baby sleep times and diaper events. Designed with big, easy-to-tap buttons for parents who are half-asleep.
- Sleep tracking — one-tap start/stop with elapsed time display and awake timer
- Breastfeeding tracking — left/right side timers with auto-switch, mutual exclusion with sleep
- Diaper logging — Pee, Poo, or Both buttons
- Activity logging — Stroll, Bath, and free-text Note events
- Manual entry — add or edit past events with date/time pickers, duration adjustment buttons, and validation (future/pre-birth date guards); supports all entry types including HC
- Bottle feeding — Donor, Pumped, and Formula tracking with configurable preset volumes; ml/oz support
- White noise — built-in sound generator (white, pink, brown, gray, blue, violet, rain, storm) with volume, duration, and fade controls; tracked in history
- High contrast viewer — built-in high contrast images for newborn visual stimulation with multiple patterns, color schemes (including three-color), and auto-advancement; viewing sessions tracked in history
- Growth tracking — weight, height, and head circumference charts with WHO percentile curves, zoom/pan (pinch or double-tap-and-drag one-handed zoom), and percentile display; latest measurements shown on home screen; individual unit toggles (kg/lbs, cm/in) with auto-conversion
- Sleep & feeding alarms — configurable alerts when baby sleeps too long or hasn't been fed (general feed and breast-specific), with custom ringtone selection, full-screen tap-to-dismiss overlay, and 15-minute interval scheduling
- Development milestones — age-appropriate milestones for motor, vision, sleep, feeding, teeth, social, language, and cognitive development with fun facts; auto-scrolls to current age
- Weather — location-based weather on calendar and home screen; current conditions, min/max temperature, hourly forecast for today and tomorrow; historical weather cached per-month; expandable weather card on home screen; powered by Open-Meteo API (no API key required)
- Telemetry — optional live sensor card on home screen showing ambient noise level (dB), temperature, humidity, and barometric pressure from phone sensors; unavailable sensors shown grayed out; disabled by default to save battery
- Calendar — monthly overview with color-coded activity dots, weather icons, and daily detail view; auto-selects current day; double-tap a day to jump to history
- Statistics — sleep, feed, and diaper charts with trend lines (24h/72h/3/7/14/30 day ranges), hourly breakdown charts, day vs night sleep pie chart, scrollable charts for large ranges
- Home dashboard — today's stats, time since last sleep/feed/diaper/bath/measurement, latest growth measurements with percentiles, weather card with hourly forecast, and optional telemetry card
- Configurable units — individual toggles for weight (kg/lbs), length (cm/in), volume (ml/oz), temperature (°C/°F), and pressure (hPa/inHg); unit choices in entry forms are local and don't affect global settings
- Configurable day/night hours — adjustable boundaries for day/night stats and auto theme switching
- History — scrollable list of all entries with date jump, entry type filter, editable and deletable with undo
- Dropbox sync — automatic cloud backup and merge across devices with immediate sync on changes; ID-based conflict resolution with modification epochs
- Import/Export — plain text file format, easy to read and share
- Theme — light, dark, or auto (switches based on configurable day/night hours)
- Home screen widget — shows current status (Awake/Sleeping/Feeding) with elapsed time and color-coded background; optionally displays baby name and age on wider widgets (3+ cells); configurable layout (baby info left, right, or hidden); tapping opens the app
- Survives app kill — active sleep/feed session persists via SharedPreferences
Data is stored as a plain text file (chosen by the user via SAF). Each entry has a unique record ID for sync conflict resolution:
