Tiny Baby Tracker vs CDC Milestone Tracker
The CDC Milestone Tracker and Tiny Baby Tracker do different jobs. The CDC app checks what your child can do at each age from 2 months to 5 years, while Tiny Baby Tracker logs daily feeds, diapers, sleep, and pumping.
Both are free, and they work well together. The CDC app helps you know what to watch for and when to talk to your doctor, and Tiny Baby Tracker shows when baby last ate and which side.
Which one should you use?
Pick CDC Milestone Tracker if
you want the CDC's milestone checklists with photos and videos, tips on when to act early, and a summary to share at checkups. It's free and comes from a public health program.
Pick Tiny Baby Tracker if
you need to log feeds, diapers, and sleep through the day and share them live with your partner. Use it next to the CDC app, since they cover different things.
Is the CDC Milestone Tracker free?
Yes, completely. It comes from the CDC's Learn the Signs. Act Early. program, and neither the App Store nor Google Play lists any in-app purchases.
Tiny Baby Tracker is free too, with no trial or paid tier. The two apps track different things, so there is no cost to using both.

What CDC Milestone Tracker does better
Official milestones from the CDC
Each checklist shows what most children can do by that age, with photos and videos so you know what each skill looks like. A nurse in one App Store review praises the quality of the information.
Help knowing when to act early
The app explains when to talk to your doctor and builds a milestone summary you can share at a checkup. One App Store review says it helps organize concerns before a visit.
Made for preemies too
It adjusts milestones for a baby born early using corrected age. It also reminds you about appointments and recommended developmental screenings.
No account needed
You can start without signing up, and the CDC says the app does not collect personal information that can identify you or your child.
What Tiny Baby Tracker does better
The daily log
Tiny Baby Tracker logs breastfeeds with a left and right timer, bottles, pumping, diapers, sleep, and solids. The CDC app doesn't log daily care, and it isn't meant to.
Live sharing with caregivers
The CDC app shares a summary you send. Tiny Baby Tracker syncs within seconds, and each caregiver joins with their own email through an invite link.
Your log moves with you
Entries are tied to your account, so a new phone keeps the whole log. One Google Play review of the CDC app says the data stayed behind after a switch to a new phone. Tiny Baby Tracker can also export every entry as a CSV.
Works in any browser
It runs in Safari or Chrome, and on a computer too. The CDC app is for iPhone and Android phones.
