The Best Baby Growth Tracker Apps

Baby Tracker by Nighp is the best baby growth tracker app overall, with free WHO percentiles from birth to age 5 and adjusted age for preemies. Baby Connect is the best paid pick, with both CDC and WHO charts for families who want to match what their pediatrician uses.

Tiny Baby Tracker is the free pick for WHO percentiles in the first 2 years, with weight, length, and head size on a chart and on a printable report. It stops at 24 months and has no CDC charts or corrected age, so the apps above it fit better for preemies and older kids.

How to choose

WHO or CDC charts

The CDC suggests WHO charts from birth to age 2 and CDC charts after that. If your pediatrician uses CDC charts for an older child, pick an app that has both.

Corrected age for preemies

A baby born early should be plotted by corrected age, based on the due date. Only some apps do this, and it makes a big difference to the percentile.

Charts past 24 months

WHO tables for babies stop at 24 months. If you want to keep tracking through the toddler years, check how far the charts go.

Free or paid charts

Several apps let you log a weight for free but put the chart behind a plan. Check whether percentiles stay free before you enter months of data.

Good

Good

  • WHO and CDC growth charts with a preemie mode
  • Widgets, Live Activities, Siri Shortcuts, and an Apple Watch app with double tap
  • One purchase covers every joined device, across iPhone and Android

Not so good

Questions

What is the best free baby growth tracker app?

Baby Tracker by Nighp has free WHO percentiles to age 5 with preemie adjusted age, though the free app shows ads. Tiny Baby Tracker is free with WHO percentiles from birth to 24 months, a growth chart, and growth on its printable report.

Should a baby growth app use WHO or CDC charts?

The CDC suggests WHO charts for children under 2 and CDC charts from age 2 on. A WHO-only app covers the baby years well. For a toddler, Baby Connect, Baby Daybook, and Sprout Baby all list CDC charts too.

Which baby growth app works for a premature baby?

Baby Tracker by Nighp, Baby Connect, Baby Daybook, and Sprout Baby all adjust for preemies using corrected age or the due date. Tiny Baby Tracker plots by birth date only, so it is not the right choice for a preemie's percentiles.

Can I track head circumference in a baby app?

Yes. Baby Tracker by Nighp, Baby Connect, Baby Daybook, and Tiny Baby Tracker all log head size along with weight and length. Tiny Baby Tracker shows a WHO percentile for head size up to 24 months.

Can I show my baby's growth chart to the pediatrician?

Most of these apps can. Baby Tracker by Nighp exports records as a PDF, and Baby Daybook added a growth table with PDF export. Tiny Baby Tracker puts growth on its printable pediatrician report, which you can print or save as a PDF.
