Gentle logging for life with your baby.

Hinata is a baby log for the first year. Three-second logs slowly reveal your baby's own rhythm.

VOICE LOGGING

Just say it. It's logged.

"Napped at noon, 120 ml at one." Say it all at once and Hinata sorts it into log suggestions. You review everything before it's saved — and speech is recognized on your device.

DIARY

Logs become memories.

A photo and a line are enough to keep today. Feelings go from wonderful to hopeless — be honest, it's allowed. Everyone's entries sit side by side, so the whole family can look back together.

  • 絶望hopeless
  • 疲れたtired
  • 普通okay
  • ほっとrelieved
  • 最高wonderful

RHYTHM & GROWTH

Your baby's rhythm, made visible.

A week of sleep, feeds and diapers in one calm chart. The baseline isn't an average baby — it's your baby, up to yesterday. Growth curves follow official Japanese reference data.

FAMILY & PRIVACY

Shared with family. Owned by your family.

One invite code brings the whole family in. Records live on your device first, and are encrypted on-device before they sync. Your baby's data is never used for ads.

ASK HINATA

For anxious nights, answers with sources.

"What is Montessori?" "How much sleep at this age?" Ask whatever is on your mind. For guidance and external-information answers, Hinata includes links to public-health and other primary sources. It never diagnoses, and when it matters it points you to real professionals.

AI answers are general information. In Japan, call 119 in an emergency, or #8000 for after-hours pediatric advice.

BUILT FOR 3 A.M.

One hand free at 3 a.m. is enough.

A dark mode that won't wake anyone. Nursing timers live on your Lock Screen and in the Dynamic Island. Or just ask Siri, without touching a thing.

"Hey Siri, start nursing"

A sunny spot in every day.
