Best Baby Tracker Apps
The best baby tracker apps for feeds, sleep, diapers and milestones, honestly compared for new parents: NewBabyOS, Huckleberry, Nara, Glow Baby, BabyCenter.
For most new parents, the best baby tracker app is the one you will actually open at 3 AM with one hand. If sleep is the specific thing breaking your household, Huckleberry is the strongest pick, because its SweetSpot feature predicts your baby’s next tired window from your own logged data, which is something a plain log cannot do. If you want simple shared logging for free across two phones, Baby Tracker by Nara is hard to beat. And if you would rather own your log outright, keep it entirely private, and pay once instead of every month, NewBabyOS is a $23 offline dashboard that covers feeds, sleep, diapers, milestones, appointments and your own recovery.
| Tool | Best for | Price | Subscription | Works offline |
|---|---|---|---|---|
| NewBabyOS | A private first-year log you own | $23 one-time | No | Yes |
| Huckleberry | Sleep predictions and expert help | Free tier; Plus about $11.99/mo | Yes | No |
| Baby Tracker by Nara | Free logging shared across caregivers | Free | No | Needs sync |
| Glow Baby | Tracking inside the Glow app family | Free tier | Optional | No |
| BabyCenter | Pregnancy-to-baby content and community | Free, ad-supported | No | No |
1. NewBabyOS - best for a private first-year log you own
NewBabyOS is a single offline HTML file you open in your browser and use like an app. There is no account, no login and no cloud. It opens on a Today screen that shows your latest feed, sleep, last diaper and mood at a glance, with quick-log buttons so you can record a wet or dirty diaper in one tap while holding the baby.
The features are the ones a first-year parent reaches for. The Feeds tab logs each feed with side, amount and duration, then draws a 7-day feed trend and keeps the day’s feed log in order. The Sleep tab records naps and night sleep, shows a 14-day sleep chart and a recent sleep log, so you can see whether last night was actually worse or just felt worse. Diapers are logged by type and time from the Today screen and counted for you. The Milestones tab is a first-year timeline for the firsts you want to remember.
There is also an Appointments tab that most trackers skip: you add pediatrician visits, see upcoming and past appointments, keep a growth log for weight and length, and work through a first-year vaccine checklist. And there is a genuinely thoughtful Mom tab, because the newborn is not the only person recovering. It has a recovery check-in, a mental-health check, a wins log for the small victories, and a short list of support lines. Everything can be exported.
The reason to choose it is ownership and privacy. It costs $23 once, with no subscription, no renewal and no expiry. Everything you type stays in your own browser on your own device, and Ecuato never receives it, because there is no server for it to reach. That matters more for baby data than people assume: your entries describe an infant’s exact daily routine and your own postpartum mood, and with NewBabyOS that record physically cannot be transmitted, sold or breached from a server, because there is no server. It works on a laptop, and you can add it to the home screen on an iPhone or Android to use it like an app, fully offline after the first load.
Be clear about who should not pick it. NewBabyOS does not predict sleep. It has no algorithm that tells you when the baby will be tired next, the way Huckleberry does, and it has no reminders, notifications, cross-device sync or account sharing. You log entries yourself, on one main device. If your central problem is sleep and you want software to tell you the optimal next nap time, or if you and your partner both need to log from separate phones in real time, one of the cloud apps below will serve you better, and you should buy that instead.
2. Huckleberry
Huckleberry is the app to beat if sleep is your real issue. Its standout feature, SweetSpot, uses your logged data to predict your baby’s next optimal nap or bedtime, and after roughly two weeks of consistent logging most parents find it genuinely useful rather than generic, because it is built from your baby’s actual patterns rather than age-based averages. That prediction is the thing none of the manual trackers here can do, and it is the honest reason to pay Huckleberry over a free log.
The free tier covers basic logging. The predictions, unlimited history and growth charts live in Huckleberry Plus, which runs around $11.99 per month or $68.88 per year, and a Premium tier at about $14.99 per month adds one-on-one sessions with certified sleep consultants. There is a free trial so you can see whether the predictions help before committing.
Who should skip it: parents who do not have a sleep problem and simply want to log feeds and diapers, since you would be paying a subscription for a prediction engine you do not need. It is also a cloud service, so your baby’s data lives on Huckleberry’s servers, which is the trade-off for the sharing and prediction features working at all.
3. Baby Tracker by Nara
Nara, formerly known as Baby Tracker, is the best free option on this list, and the one to pick when two caregivers need to share logging without paying anything. It is completely free with no premium tier, no ads and no in-app purchases, which is genuinely unusual in this category. It tracks feeds, pumping, diapers, sleep and wake windows in a calm, clean interface, syncs across parents and devices, and handles twins or multiple children well. It even includes some parent-side features for pregnancy and postpartum notes.
Who should skip it: anyone who specifically wants sleep predictions, because Nara logs and shares beautifully but does not forecast the next nap the way Huckleberry does. And because sharing and sync are the point, it is a connected app, so your data lives in its cloud rather than only on your device. If offline-only privacy is your priority, that is the trade-off.
4. Glow Baby
Glow Baby is the baby tracker inside the larger Glow family of apps, which also spans period and pregnancy tracking. It covers the standard ground of feeds, diapers, sleep, pumping and growth, with a free tier for basic tracking and a subscription that unlocks premium features and works across the company’s other apps. If you already use and trust Glow for cycle or pregnancy tracking, staying in the same ecosystem is a reasonable reason to choose it.
Who should skip it: parents who want everything free forever, since the more useful features sit behind a subscription, and anyone who has no interest in the wider Glow ecosystem, because on baby tracking alone it does not clearly beat the free Nara or the prediction-focused Huckleberry.
5. BabyCenter
BabyCenter is less a dedicated tracker and more a pregnancy-to-parenthood companion with tracking attached. Its strength is content and community: week-by-week development updates, medically reviewed articles, fetal development videos during pregnancy, and a large parent community, all free and supported by ads. It does include a baby tracker with a growth chart, feeding guides and a sleep log, so it can cover the basics.
Who should skip it: parents who want a focused, fast logging tool. The tracker is competent but secondary to the articles and community, the app is ad-supported, and it is not built to be the streamlined thing you tap at 3 AM. If reassurance, reading and community are what you actually want alongside light tracking, it is a good fit; if you want a clean logging dashboard, look elsewhere.
How to choose
- Pick NewBabyOS if you want a private log you buy once and keep, covering feeds, sleep, diapers, milestones, appointments and your own recovery, with nothing leaving your device.
- Pick Huckleberry if sleep is your central struggle and you want software that predicts the next optimal nap or bedtime from your own data.
- Pick Baby Tracker by Nara if you want free, clean logging that two caregivers can share across phones with no subscription.
- Pick Glow Baby if you already live inside the Glow app ecosystem and want your baby tracking in the same place.
- Pick BabyCenter if you want week-by-week content, community and reassurance alongside light tracking, and you do not mind ads.
A note on baby-data privacy
It is easy to forget how detailed a baby log is. Over a year it becomes a minute-by-minute record of when your child eats, sleeps and wakes, plus your own mood and recovery notes. Most tracking apps upload that to their servers so sync and predictions can function, and that is a fair trade if you want those features, but it does mean a company holds the record. If you would rather that data never leave your hands, an offline tool is the only way to guarantee it, because it has no server to send anything to in the first place. That is the specific gap NewBabyOS fills, and it is why some parents keep a private offline log even if they also use a cloud app for one feature like sleep.

None of these tools, ours included, is a medical device: for anything about your baby’s health, weight or feeding, your pediatrician is the right call, not an app.
Frequently asked questions
What is the best baby tracker app?
It depends on your main problem. If sleep is the thing wrecking your house, Huckleberry is the best pick because its SweetSpot feature predicts your baby's next tired window from your logged data. If you just want free, shared logging across two phones, Baby Tracker by Nara is excellent. If you want a private log you buy once and keep forever, NewBabyOS is a $23 offline dashboard that covers feeds, sleep, diapers, milestones and your own recovery.
Is there a baby tracker without a subscription?
Yes. NewBabyOS is a one-time $23 purchase with no subscription, no account and no cloud, and Baby Tracker by Nara is free with no premium tier at all. Most of the big sleep-focused apps, including Huckleberry Plus, charge a recurring monthly or yearly fee for the features people actually download them for.
Are baby tracker apps private with my baby's data?
It varies a lot by app, and it is worth reading the privacy policy before you type in feeding times and your postpartum mood. Most cloud apps upload your entries to their servers so sharing and predictions can work, which means a company holds a detailed record of your newborn's routine. NewBabyOS stores everything in your own browser on your own device, and Ecuato has no server to receive it, so nothing you type ever leaves your phone or laptop.
Can a baby tracker predict when my baby will sleep?
Some can, and this is the one thing a manual log genuinely cannot do. Huckleberry's SweetSpot predictions estimate your baby's next optimal nap or bedtime after about two weeks of consistent logging. NewBabyOS does not predict anything; it records what already happened so you can spot patterns yourself, so if algorithmic sleep timing is your priority, pick a sleep-focused app instead.
Do I need an app, or is a notebook fine?
A notebook is fine and plenty of parents use one. The advantage of a structured tracker is that it does the math for you: totals per day, a feed trend, a sleep chart and a running diaper count, without you tallying anything at 3 AM. NewBabyOS is essentially a notebook that adds the totals and charts automatically while staying fully private.
Will a baby tracker work offline?
NewBabyOS works fully offline after the first load, because it is a single HTML file with no server calls. Most app-store baby trackers need a connection to sync, log in or show predictions, and some features stop working without one. If you want something that works in a basement nursery with no signal, offline-first matters.
Can two parents use the same baby tracker?
With cloud apps like Nara, Glow Baby and Huckleberry, yes: both parents log on their own phones and the data syncs. NewBabyOS is single-device by design, so it does not sync across two phones in real time. If shared, real-time logging between caregivers is a must-have, choose a cloud app; if one main device is enough, the offline option keeps your data private.
