All the popular baby trackers log the basics well: feeds, sleep and diapers. Where they really differ is what they charge for. Huckleberry's nap predictions are paid. Nara Baby becomes read-only after a 7-day trial. Baby Tracker and Baby Daybook put syncing with a partner in their paid versions, and Glow Baby charges to add a second caregiver. Livia puts next-nap estimates, real-time partner sync and offline logging in one app, with no ads, and is free during early access.
We make Livia, so read this with that in mind. Every claim about another app below links to that app's own website, help center or App Store listing, as checked in October 2026. Prices and plans change often, so check those pages before you decide.

Where does Livia stand out?
1. What the others sell as premium is free
The next-nap estimate, partner sync, growth charts and full history, the features the apps below put in their paid plans, are all included. Nothing needs a subscription, there are no ads, and you never enter a card. They stay free after early access too; the one thing Livia will charge for is Ask Livia, the assistant that's coming.
2. It knows when the next nap is likely
Livia estimates the next nap and bedtime from your baby's own rhythm. Until it has enough of your log, it uses typical awake times for their age. It's on the home screen, next to how long it's been since the last feed. Huckleberry's equivalent, SweetSpot, needs a paid Plus or Premium plan. Baby Tracker's "What's Next" cues come with its paid Plus plan. Exactly how Livia's estimate works, and what it rests on, is in How does Livia know when the next nap is likely?
3. Both phones, same night, in seconds
Invite a partner, grandparent or nanny by email. Every entry shows up on their phone in real time, and you can see who logged what. Each person has their own sign-in, so nothing gets overwritten (how sharing works). Baby Daybook keeps Family Sync in Premium, and Glow Baby needs its Family Plan to add a second caregiver.
4. Logging never waits for a signal
Every entry is saved on your phone first and syncs when you're back online. A feed logged in a basement, on a plane or at grandma's is never lost or stuck behind a spinner.
5. It catches the slips you make half asleep
Livia checks the log as you go. Typed 1200 ml? It asks "Did you mean 120 ml?" You and your partner both logged the same feed? It asks which one to remove. A sleep timer left running gets a gentle check, and a missed nap gets a question in History, not a gap in your data. The full list is in Why does Livia ask "Did you mean 120 ml?"
6. Last night is one number
Most trackers cut a night's sleep at midnight. Livia counts a sleep that starts in the evening as that night's, in the morning it ends in, so a day in History is last night plus its naps. Insights then says what stood out, with the source named when a guideline is quoted. How Livia counts a night.
7. Calm, not cluttered
Dark, one-handed and quiet: no shop, no community feed and no upsells between you and the Log button. You can switch off what you don't track, and those buttons disappear.
How does Livia compare to Huckleberry?
Huckleberry is one of the best-known names in baby sleep. Its free plan covers logging and syncs across devices. Its headline feature, SweetSpot nap timing, is part of the paid Plus and Premium plans, alongside sleep plans and an AI chat. Choose Huckleberry if you want a personalized sleep plan and coaching. Choose Livia if you want a next-nap estimate, real-time partner sync and a calm log without a subscription. The longer head-to-head: Livia vs Huckleberry.
How does Livia compare to Nara Baby?
Nara Baby is clean and ad-free, and it used to be free. According to Nara's own FAQ, it now starts with a 7-day trial and then needs a subscription or a lifetime purchase. Without one, your log is read-only: you can view and export it, but not add to it. Choose Nara if you're happy to pay for a polished, mature app. Choose Livia for the same calm, ad-free experience, with a next-nap estimate on the home screen, free. The longer head-to-head: Livia vs Nara Baby.
How does Livia compare to Baby Tracker – Newborn Log?
Baby Tracker by Nighp is one of the most-rated trackers on the App Store, and it logs almost everything. Its "What's Next" cues need the paid Plus plan. Syncing with other phones is part of the paid full version and uses a shared sync group: according to its FAQ, joining one replaces the data already on the joining phone. Choose Baby Tracker for the widest range of log types. Choose Livia for free partner sync, a free next-nap estimate, and caregivers who each have their own sign-in.
How does Livia compare to Baby Daybook and Glow Baby?
Both log a wide range of things for free, but both charge to share the log beyond one phone or one caregiver: Baby Daybook's Family Sync is Premium, and Glow Baby needs the Family Plan. For two parents doing night shifts, that's the feature you need most.
Where is Livia not the right pick (yet)?
- You want a sleep-training plan or a coach. Livia gives routine estimates, not sleep programs. For that, Huckleberry's paid plans are built for it.
- You need to export a PDF report today. Livia doesn't have export yet.
- You want to know where your data goes before you start. Read Is Livia private? and the privacy policy.
- You want an app with years of history. Livia is new, in early access before its App Store launch. The upside is that your feedback goes straight to the person building it.
Which baby tracker should you choose?
If you want everything that matters at 3 am — fast logging, the next nap, both phones in sync, no ads — without a subscription, get early access to Livia. It's free, and your log carries over when Livia reaches the App Store.
Whichever app you pick, the best tracker is the one you'll still open at the fifth feed of the night. And no app replaces your pediatrician: bring any question about feeding, sleep or growth to them.
