A cute baby tracker for new parents. Log feeding, sleep, diapers, solids, growth and vaccine references—no account required, with a 14-day trial.
【A Baby Routine Tracker for New Parents and Caregivers】
Parenting is already busy. Logging your baby’s day should feel simple. BiuLog keeps feeding, sleep, diapers, solids, growth, vaccines, and routine changes in one place, with quick actions, a gentle design, and an easy way to look back, share handoffs, and care together.
BiuLog is great for:
・Families with newborns
・Parents tracking feeding, sleep, and diaper changes
・Caregivers organizing solids, growth records, and vaccine information
・Families who want to record baby routines together
・Parents sharing care details with babysitters, childcare teachers, postpartum caregivers, or daycare providers
【Quick One-Handed Logging】
Log feeding, sleep, diapers, and solids in just 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 bottle feeding, record expressed breast milk and formula amounts separately in ml, helping parents understand each feeding and daily rhythm.
【Pee, Poop, and Diaper Changes】
Diaper logs can be recorded as pee, poop, or pee + poop. BiuLog also helps organize daily diaper changes, making it easier for caregivers to understand your baby’s condition.
【Solids and Daily Routine】
Record food type, amount, and notes for solids. Review each day’s full timeline to see what your baby ate, how long they slept, how much they drank, and how many diapers were changed.
【Family Sharing】
With Pro, you can create a family share and invite up to 2 family members to join for free and share Pro features. Family members can view and record baby routines together, making it useful for parents, grandparents, and regular caregivers.
【Caregiver Sharing】
The Caregiver Plan is designed for babysitters, childcare teachers, postpartum caregivers, and daycare providers. Caregivers can share baby care records with parents and record daily care together, helping parents understand their baby’s routine during care hours.
【Vaccine Records and Reminders】
Use built-in vaccine schedule references to record vaccination status, completion dates, and upcoming doses, making it easier to organize vaccination information without searching through paper records.
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 precious milestones such as rolling over, crawling, walking, and saying first words.
【Routine Charts】
View feeding amounts, sleep, pee, poop, diaper changes, and solids by week, helping parents better understand their baby’s recent routine.
【Soft Watercolor Style and Custom Home Screen】
BiuLog includes a gentle watercolor-style home screen. With Pro, you can customize button text, colors, fonts, images, and icons, or place your baby’s photos on the home screen.
【Multiple Baby Profiles】
Pro supports multiple babies, making it useful for twins, siblings, and families caring for more than one child. Each baby can have their own data, records, and home screen style.
【Export, Backup, and Restore】
Export activity records as CSV, or create a complete JSON backup including baby profiles, daily logs, growth records, vaccines, custom buttons, images, and settings.
【Start Without an Account】
BiuLog can be used without creating an account. Basic daily logging is free. If you want ad removal, Family Sharing, multiple baby profiles, advanced charts, full backup, and more customization features, you can upgrade when needed.
Ad removal and Pro features for family use are one-time purchases. The Caregiver Plan is a monthly subscription for professional caregivers who need to share baby care records with parents.
BiuLog makes baby tracking quick, cute, and easy to organize.
