Made for you if…
Built for one kind of parent
You're done paying a subscription every year for an app you already rely on.
You don't want your baby's data living on someone else's server.
You're the one doing the tracking — and you want it fast, one-handed, in the dark.
The difference
Not a privacy policy.
A privacy property.
Most baby trackers send your child's data to the cloud. This one can't — it has no servers and makes no network calls. The app works in airplane mode because it never needed to leave it. No sign-up, no email, no ads, no analytics, no tracking.
Private doesn't mean fragile. Automatic backups to a folder you control mean you're never one dropped phone away from losing your memories. See how backups work →
Built for 3am
Three taps. One thumb. In the dark.
Log a feed, sleep or diaper in about three seconds, one-handed, from the bottom of the screen. Timers keep running if you lock or restart your phone. A genuine dark theme keeps things gentle in a dark room — and every entry is easy to edit if you mis-tap while half-asleep.
Calm intelligence
Guidance, not alarms.
The app reads your baby's rhythm and shows what it means — in calm ranges, never in alarms. Sleep-pressure and wake-window guidance are tuned to your baby's age and gently personalize to their own pattern. WHO growth percentile charts are bundled offline. And when a normal-but-worrying phase arrives, it tells you what's common at this age — calmly, with the source — instead of leaving you to a fear-driven search.
Is this normal?
The 3am question, answered calmly.
When your four-month-old suddenly wakes every hour, or your six-week-old cries for hours, you reach for a search engine — and land in fear. Offline Baby Tracker answers the same question on your phone: this is common at this age, here's why, and it passes. Every note is short, calm, and shows its source. No countdowns. No “leaps” to brace for. No score. Just context that helps you relax.
Milestones as ranges, not deadlines
See the age windows most babies reach motor and language milestones — from the WHO Motor Development Study and CDC guidance — shown so a wide range of ages reads as completely normal.
A calm development timeline
The 4-month sleep change, the crying peak, day–night rhythm, nap transitions, clinginess, percentile shifts: what's happening now, what's already passed, and what's commonly ahead — each with its source.
Reassurance, never prediction
No “leap in 3 days,” no regression countdown, no “your baby is behind.” Notes describe what's common and cite published research (WHO, CDC, AAP).
Built to calm you down, not wind you up.
Tuned to corrected age: for babies born early, every age band uses corrected age — so the context fits your baby, not a calendar.
Everything in one place
Everything you need, nothing you don't
Breastfeeding, handled
Per-side timers, pause and resume, latch and comfort notes.
Every feed, one place
Bottle and pumping, amounts and sessions, all together.
Sleep that adds up
Naps and night, with timers resilient to locks and restarts.
Diapers at a tap
Wet, dirty or both — logged in a single thumb-press.
Watch them grow
Weight, length and head plotted on WHO percentile charts.
Health on record
Temperature, medications, vaccines and illness notes.
Know what's normal
Milestones and calm developmental notes, with sources — no leap countdowns.

From parents like you
Why a parent built this
At 3am with a newborn, I didn't want to create an account, accept a privacy policy, or pay a subscription to write down when my daughter last fed. I wanted one calm screen, a thumb-sized button, and the certainty that her data was nobody's business but ours.
So I built the tracker I wished existed — one that keeps everything on your phone, costs once, and tells you what the numbers mean without ever sounding an alarm. No servers means nothing to leak, and nothing to rent.
Honest before you buy
Made for one parent, one phone.
Offline Baby Tracker is designed for a single caregiver. Real-time sync between two phones would mean putting your baby's data in the cloud — and that's exactly what we refuse to do. So we made the opposite trade on purpose: total privacy, on one device. You can still move everything to a new phone with a backup. We tell you this before you buy, because honesty is part of the product.
Questions, answered
On your phone, only. The app has no servers and makes no network calls. Backups go to a folder you choose.
Your automatic backup restores everything onto the new phone. You're never one dropped phone away from losing your data.
No. No sign-up, no email, no login — ever.
No. It's a one-time purchase of €9.99. No upsells, no ongoing fees.
Yes — through the App Store or Google Play under their standard refund policies.
It supports recent iPhones and Android 10 and newer. Check the store listing for exact versions.
It's a single-caregiver app — there's no real-time sync between devices. That trade-off is what keeps your data fully private and on-device. You can move your data with a backup file.
It shows the ranges most babies reach each milestone — framed so a wide range of ages is normal, never a pass/fail score. The only nudge it ever gives is a gentle “this could be worth mentioning at your next pediatric visit.” It’s reassurance, not a verdict.
No — on purpose. We don’t predict leaps or regressions or count down to anything; that fixed-timing approach isn’t supported by the evidence and tends to create anxiety. We describe what’s common at each age, show the source, and let you relax.
No. It’s a tracking and guidance tool, not a medical device. Guidance references published standards (WHO Child Growth Standards; WHO Motor Development Study; CDC/AAP developmental guidance; Mindell & Williamson wake-window synthesis). Talk to your pediatrician with any concerns.
Completely. It's offline-first — it even works in airplane mode.
