## What is Lumi?

Lumi is a calm, evidence-aware baby tracker for the early years.

  Log sleep, feedings, diapers, and health in a single tap. Watch your
  baby's day unfold in beautiful charts. Trust smart predictions that learn
  from your baby's unique rhythm.

  WHY LUMI

  • All data stays on your device (iCloud sync optional)
  • Built for the real exhausted-parent moments — single-tap logging,
  glance-friendly home screen
  • Premium that earns its keep — sleep predictions, lullabies, Live
  Activity routine

  WHAT YOU CAN TRACK
  • Sleep — ongoing & finished entries, with cross-midnight handling
  • Feeding — breast, bottle, solid; duration & amount
  • Diaper — wet, dirty, mixed
  • Health — medication, fever, vaccination, doctor visits

  PREMIUM FEATURES

  you when the next sleep window is approaching
  • Unlimited entries & full-history analytics — 30-day comparison cards,
  daily trend charts, longest-stretch metrics, average bedtime
  • Music-box lullabies — Brahms, Mozart, Frère Jacques and more, plus
  natural soothing sounds (white noise, heartbeat, rain, ocean)
  • Live Activity routine — your day flows live on the Lock Screen and
  Dynamic Island; one-tap "Done" without unlocking
  • Memory Board — 8 milestone keepsakes from welcome to age five, plus your
   own moments with photos
  • Smart insights — calm, evidence-aware suggestions based on real data
