## What is BiuLog?

【A Baby Routine Tracker for New Parents and Caregivers】

BiuLog keeps feeding, sleep, diapers, solids, growth, vaccines and routine changes in one place. Quick actions and a gentle design help new parents and caregivers look back, share handoffs and care together.

【Childcare Institution Lookup】
Search Taiwan and Japan childcare listings and official sanction, warning and inspection records. No record means no guarantee; data can lag. Check official sources and visit providers.

【Quick One-Handed Logging】
Log feeding, sleep, diapers, and solids in a few taps. Tap to record right away, or long press to add an earlier time, even during late-night care.

【Breastfeeding, Expressed Milk, and Formula】
Track breastfeeding with left and right side timers. For bottles, record expressed breast milk and formula separately in ml.

【Pee, Poop, and Diaper Changes】
Log pee, poop or pee + poop, and count daily diaper changes to support care handovers.

【Solids and Daily Routine】
Record food types, amounts and notes. The daily timeline shows meals, sleep duration, milk intake and diaper changes.

【Family Sharing】
Create a family share and invite up to 2 family members. Family members can view and record baby routines together, useful for parents, grandparents, and regular caregivers.

【Caregiver Sharing】
Caregiver sharing supports babysitters, childcare teachers, postpartum caregivers, and daycare providers. Caregivers and parents can share and record daily care together.

【Vaccine Records and Reminders】
Use vaccine schedule references to keep vaccination status, completion dates and upcoming doses together.

Note: Vaccine schedules are for personal records and reminders only. Actual vaccination timing and details should follow your doctor, official guidance, and your baby’s health record booklet.

【Growth Records and Milestones】
Track height, weight, and head circumference, and save milestones such as rolling over, crawling, walking, and saying first words.

【Teeth, Family Health, and Parent Chat】
Log teeth 1–20 (eruption date/age), checkups, symptoms, temperature, medicines, allergies and food reactions. Chat with parents; send private messages or group updates. Global/Chinese/Japanese rooms; no auto-translation. The home chat icon shows unread announcements and private messages. Sign in to privately message BiuLog’s developer: app help, issue reports, feature ideas.

【Routine Charts】
View feeding amounts, sleep, pee, poop, diaper changes, and solids by week to understand your baby’s recent routine.

【Soft Watercolor Style and Custom Home Screen】
BiuLog includes a gentle watercolor-style home screen. Customize button text, colors, fonts, images, and icons, or place your baby’s photos on the home screen.

【Multiple Baby Profiles】
BiuLog supports multiple babies for twins, siblings, and families caring for more than one child. Each baby can have their own data, records, and home screen style.

【Stories, Songs and Animal Exploration】
Enjoy 16 books: stories such as The Three Little Pigs, songs and interactive farm, wild, forest and dinosaur animals. Tap animals to hear sounds. Languages vary by book; some stories and exploration books offer Chinese, Japanese and English. Dinosaur sounds are imaginative creations.

【Export, Backup and Personal Cloud Saving】
Export CSV, or use full JSON backup and restore for baby profiles, daily records, growth, vaccines, custom buttons, images and settings. Separately, after sign-in, personal cloud saving covers daily records, growth, milestones and vaccines. Restore previously uploaded data with the same account on another device. Photos, custom buttons and preferences are not included in personal cloud saving.

【Start Without an Account】
Start basic daily logging without an account. Family sharing and cloud features require sign-in.

Quick, cute baby tracking that stays easy to organize.
