Raise your baby.
And actually enjoy it.
The only baby tracker that tells you what's going on — not just what to write down.
Feeding, sleep, diapers, growth, milestones — tracked in seconds, interpreted automatically. Sleep regressions spotted early. Overtired windows flagged before bedtime. The 3am question “what's wrong with him?” answered by your own data.
Every other app gives you charts.
Lulu gives you answers.
Built on your actual data plus ~700 age-aware rules grounded in WHO / AAP / CDC guidelines, Wonder Weeks, and cross-category signal detection. Here's the kind of thing it's saying to parents this week:
He tends to get fussy about 20 minutes before he's actually hungry. A quick feed now keeps the afternoon calm.
Putting him down 30 min earlier tonight usually helps this pattern. You've done it 4 times — it worked 3 out of 4.
Based on his growth curve, 6-month onesies will be too short around May 7. Worth ordering the next size this weekend — before you need it at 11pm.
A regression is likely within 48 hours. Tonight: consider an earlier bedtime and a darker room.
Expect more clinginess, disrupted sleep, and new fears. It's not a regression — it's a growth phase. 2–4 weeks on average.
You haven't logged it yet. If he's doing it, tap to confirm. If not by 9m+2w, we'll gently suggest mentioning it at the next visit.
These are advice patterns, not medical diagnoses. Lulu is designed to help you notice things early so you can talk to your pediatrician sooner — never to replace one.
Stop guessing. Start noticing.
The hard part of parenting isn't the tracking — it's the 3am question “is something wrong?”. Lulu watches the patterns so you don't have to. You raise the baby. The app quietly flags what's worth a second look.
Everything you need. Nothing you don't.
Designed to disappear into the background — until you need it.
Feeding timer, sleep with moods, diapers, meds, temperature, teeth, outings, growth — one tap, one-handed, even at 3am.
Invite your partner, grandparents, nanny — anyone who looks after your baby. Each of them logs what they did from their own phone, and it all lands in one place. You open the app and see the full day, not fragments from five different texts.
WHO / AAP / CDC percentile curves plus a 3-week-ahead clothing-size forecast. Buy the next size before they outgrow today's.
WHO schedule with push reminders 7 days before each shot. Mark done, keep the record forever, share with your pediatrician.
Every log saves to your device first. Airplane mode, no signal, 3am in a hotel room — it just works.
One-tap CSV / JSON export. 30-day soft-delete recovery. Account deletion anytime. No ads, no third-party trackers, no data sold.
Your baby's data is yours.
