Why Preem exists
Built for the gaps general baby apps leave open
General baby-tracking apps and single-purpose NICU nonprofit tools weren't designed around the thing that matters most for preemie families: adjusted age. Preem was.
| Capability | Preem | General baby appse.g. BabyCenter, Ovia Health | NICU nonprofit appse.g. The Preemie App |
|---|---|---|---|
| Milestones based on adjusted (not birth) age | |||
| Daily NICU diary for feeds, weight & skin-to-skin time | |||
| Built around the NICU-to-home journey, not just birth date | |||
| Shareable reports for your care team | |||
| Low-friction pricing (free diary + affordable premium) |

Everything in one gentle place
Everything Preem does for your family
From your baby's first days home to first bites, Preem grew one gentle feature at a time — all of it in the same warm place, so you never have to hunt for what you need.
Track
Your baby's story, on their own timeline
Baby profile & adjusted age
Enter your due date and birth date once — every insight in Preem is calculated by adjusted age, not just the calendar.
Milestone tracker & goals
Warm, illustrated milestones filtered to your baby's adjusted age, each with gentle "ways to help your baby reach this milestone" ideas — plus set a goal on any milestone and watch it move from in progress to achieved.
Add today's photo
The diary starts with one tap. "Add today's photo" sits at the very top — take or upload a picture and it is saved as a diary entry straight away, automatically stamped with your baby's corrected age. No typing required, and it appears in your timeline immediately.
Private NICU diary
A private daily diary with 15 mood options, NICU note types like Morning Rounds and Doctor Conversation, and a place to save Core Memories — First Hold, First Feed, Coming Home, and more.
Fenton growth curves & corrected age
Tap "Add measurement" to log weight, length, or head circumference and instantly see it plotted on preemie-specific Fenton growth charts (22–50 weeks) with real 3rd–97th percentile bands — using corrected age, not the WHO/CDC term-baby charts. See a daily-updating corrected-age line (e.g. "33w+4 corrected age") and a countdown to the baby's due date.
Feed
From first grams to first bites
Weight logging
Log weight in grams, kilograms, or pounds & ounces — Preem converts automatically right next to the input.
Feeding amounts, every method
Track feeding amounts in ml or oz with a simple toggle — bottle, breast, NG tube, OG tube, G-tube, or other, so however your baby is fed, it's counted.
Food & Solids by adjusted age
A dedicated Food & Solids section with clear adjusted-age bands — 0–3, 4–6, 6–9 and 9–12+ months — that highlights where your baby is right now, plus the full starting-solids timeline and a browsable food library with a liked, disliked, or neutral reaction for every food.
Pump
For every parent who pumps or breastfeeds
Per-side tracking
Log Left, Right, or Both sides with a live combined total as you go.
Pause & countdown timer
A pause-and-resume session timer, plus a countdown mode with 5–45 minute presets or your own custom time.
Reminders & location
Set an adjustable interval between sessions with an on/off alarm, and log where you pumped — Home, NICU, or on-the-go.
NICU
Built alongside NICU families, for NICU days
Kangaroo Care tracker
A skin-to-skin timer with a running daily total, so every minute of Kangaroo Care is counted.
NICU Firsts with photo mementos
Earn a keepsake badge for every first — first hold, first bottle, first day off oxygen. Add photo mementos to any first, even ones you saved earlier, and tap to view them full-size.
Respiratory support log
Follow your baby's breathing support journey from room air through cannula, CPAP, and ventilator as they wean.
NICU glossary
Plain-language definitions across Monitoring, Breathing/Respiratory, Feeding/Nutrition, Labs/Medical, Care Terms, and Growth.
Rounds question checklist
A ready-made list of questions to bring to morning rounds, so you never leave a conversation wishing you'd asked more.
Support
You don't have to do this alone
Daily affirmation
A fresh, rotating affirmation waiting for you each morning.
Daily developmental tips
Today's little practice: play peek-a-boo in the mirror to encourage emotional expression and social connection — a fresh, age-appropriate activity idea every day, with an optional gentle reminder at whatever time works for you.
“Ideas for this age” dashboard hub
Right below your baby's adjusted age, an “Ideas for this age” card surfaces the 2–3 tips that match right now. Beneath it, a calm one-tap hub groups every part of Preem — Track, Journal (your NICU diary, daily log, Journeys stories, and photos), Care, and Family — so nothing is ever more than a tap away.
Matched Journeys
A “Journeys” space of warm, anonymized stories from babies like yours — matched on gestational age at birth, adjusted age and whether you’re still in the NICU or home. Every one ends on a hopeful, milestone-oriented note. Clearly-labelled example stories to begin with, never real patient data.
Multiples support
Tracking built for twins and triplets, with a combined side-by-side view for multiples.
Family sharing
Opt-in sharing so your spouse or family can follow along, only if and when you invite them.
Share your feedback
A direct line to tell us what's working and what isn't — Preem keeps growing around real NICU families.

You're not doing this alone
“Seeing milestones tracked by her adjusted age instead of her birth date finally made sense of everything. I stopped panicking every time a baby app told us we were 'behind.'”
Maria R.
Mom to a 28-weeker
“The NICU diary became the thing I looked forward to every night. Now it's a beautiful record of the hardest, most hopeful months of our lives.”
David K.
Dad, twins born at 31 weeks
“Our NICU handed us Preem the day we went home. Having one place for weight, feeds and milestones took so much pressure off that first week.”
