This Stage: what many babies are like this month

Daily photos

Up to 9 photos a day, one as the cover. A monthly calendar where each day shows its cover photo. Recaps for each month, 1 month, 100 days and birthdays. Start during pregnancy and keep going after birth.

Growth

Weight, length and head circumference on growth charts, with approximate percentiles. WHO Child Growth Standards; in mainland China, the national standards from the National Health Commission. Corrected age for babies born preterm.

Up Next

Plan checkups and other visits, with reminders the day before and that morning. Note questions before a visit, and what was measured and what the doctor said after.

Supplies

Track diapers, formula, wipes and more: how many are left, how many a day, and roughly when they run out. A reminder when something is running low.

This Stage

One page for each month in the first year, then by age range: what many babies are like at this age and how you can spend time together. No tests, no scores.

Widgets

Home Screen and Lock Screen widgets with the day count, today's photo and the next visit.

DayByDay Plus

A one-time purchase with Family Sharing. No subscription. Growth films and growth books are in Plus. Photos, charts, reminders, recaps, widgets and export stay free.

Your data

No account, no ads, no third-party SDKs. DayByDay has no servers of its own. Your photos and records stay on your iPhone and in your private iCloud, where we cannot see them. See the Privacy Policy.
