Baby's size, every day
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Baby's size during pregnancy, every day.
How Big is Baby Today shows your baby's average size for today's exact day of pregnancy, more granular than a fruit-by-week. Enter your due date, and every day you'll see:
• Today's gestational age and the average length and weight
• An estimated cell count
• A fresh list of size comparisons with new categories each day
Have a real measurement from an ultrasound? Enter it and the predictions adjust to your baby.
Figures are population averages (50th percentile) based on published fetal growth charts (www.nichd.nih.gov). These are estimates for fun and information only — not medical advice.
Version 2.0
• New feature - Track multiple babies! Add as many as you like.
• Refinements and fixes throughout.
