There is a specific kind of exhaustion that comes not from sleep deprivation itself, but from not understanding it. You know your baby is tired. You know they need to sleep. But the nap window passes in the five minutes you spent second-guessing, and now you have an overtired baby and another 45 minutes before you can try again.
Sleep tracking doesn't fix the exhaustion. But it fixes the guesswork. When you can look at a week of data and see that your baby's best naps happen when you put them down 87 minutes after waking — and that number is consistent — the chaos starts to have a shape.
These are the apps that help you find that shape.
What to Look for in a Baby Sleep Tracker
Wake Windows, Not Just Timestamps
Logging when baby slept is useful. Knowing when the next sleep window opens is more useful. The best apps turn your logged data into a prediction — "based on last wake time and your baby's pattern, nap window opens in 20 minutes." That's the difference between a log and a tool.
Feeding Integration
Sleep and feeding are inseparable in the newborn phase. Wake windows start from the end of the last feeding. An overtired baby who hasn't eaten enough won't settle. The apps that let you track both together give you a much more complete picture than sleep tracking alone.
Free Tier That's Actually Usable
Some sleep apps lock the entire useful feature set behind a paywall on day one. Before committing, check whether the free tier covers at least basic sleep logging — enough to see if the app fits your workflow before you pay.
#1. Huckleberry — The Gold Standard for Sleep Tracking
⭐⭐⭐⭐⭐ Rating: 4.8/5
Price: Free tier available, full access ~$9.99/month Best For: Parents who want data-driven nap predictions
Huckleberry built its reputation on one feature: SweetSpot. Based on your logged wake times and your baby's individual patterns, it predicts the optimal window to start the nap — down to a 30-minute range. For parents who have been guessing, this is the feature that changes everything.
The science behind it is legitimate. Wake windows aren't one-size-fits-all — a 6-week-old and a 10-week-old have different tolerances, and your baby's specific tolerance is different from the average. Huckleberry learns your baby's pattern from your logs and reflects it back as a recommendation.
What the free tier covers:
- Basic sleep, feeding, and diaper logging
- History view
- Basic insights
What requires the paid plan:
- SweetSpot nap predictions
- Detailed analysis and reports
- Smart analysis across multiple days
Pros:
- ✓ SweetSpot predictions are genuinely accurate for most babies
- ✓ Clean, easy-to-read interface
- ✓ Tracks feeding alongside sleep
- ✓ Large community of parents using it — good peer support
Cons:
- ✗ The features that matter most require $9.99/month
- ✗ Requires account and data goes to their servers
- ✗ Can feel overwhelming at first
Best for: Parents whose main challenge is nap timing and schedule building.
#2. Baby Tracker by Amila — Best Free Option
⭐⭐⭐⭐ Rating: 4.2/5
Price: Free with ads, ~$2.99/month to remove Best For: Parents who want free sleep tracking on any device
Baby Tracker by Amila is one of the most downloaded baby apps on both iOS and Android, and for sleep tracking specifically, the free tier is genuinely functional. You can log naps and overnight sleep, see daily totals, and track the pattern over time — all without paying.
The cross-platform support makes it the best option for households where both parents have different phones. One logs on Android, one on iPhone, both see the same data.
The trade-off is ads and a slightly older interface. Not a dealbreaker for most parents, but noticeable.
Best for: Android users, mixed-device households, anyone who needs free sleep tracking now.
#3. Nara Baby — Best Modern Design
⭐⭐⭐⭐ Rating: 3.9/5
Price: Free tier + premium Best For: Parents who want the most current-feeling interface
Nara Baby is the newest entry with the most polished design — the interface feels modern and the logging flow is smooth. Sleep tracking is well-implemented, and the app covers feeding and diapers alongside it.
It's improving quickly, which also means it's less battle-tested than Huckleberry or Baby Tracker. For a tool you're relying on at 4am, that matters. But if design and user experience are priorities for you, Nara is the best-looking option in the category.
Best for: Early adopters who want a modern app and are willing to be patient with occasional rough edges.
#4. Sprout Baby — Best One-Time Purchase
⭐⭐⭐⭐ Rating: 3.8/5
Price: ~$4.99 one-time Best For: Parents who hate subscriptions
Sprout covers sleep, feeding, growth, and diapers for a single upfront payment — no monthly fee, ever. The interface is clean and the sleep logging is solid. It doesn't have Huckleberry's predictive features, but if you just want to log and see history without a recurring bill, Sprout delivers.
Less actively maintained than the top picks, but reliable for the basics.
Best for: Parents who want a one-time purchase and don't need AI-powered predictions.
#5. Glow Baby — Best Community Features
⭐⭐⭐½ Rating: 3.6/5
Price: Free with ads, premium available Best For: Parents who want community support alongside tracking
Glow Baby combines sleep and feeding tracking with an active community forum. The free tier covers the basics and the community aspect is genuinely useful — being able to ask "is this sleep pattern normal?" and get answers from real parents at the same stage is something other apps don't offer.
Privacy note: ad-supported on the free tier, which means data is used to serve those ads. If that concerns you, stick with Huckleberry or Baby Tracker.
Best for: Parents who want peer connection alongside their tracking data.
#6. A Simple Notebook — Underrated Last Resort
⭐⭐⭐ Rating: 3.0/5
Price: Free Best For: Week one, before you've chosen an app
A timestamped notebook entry — "down at 9:14, up at 10:47" — is technically a sleep log. No downloads, no learning curve, completely private. You'll outgrow it fast, but if you're in the hospital or the first chaotic days home and need to track something right now, it works.
Upgrade to a real app before week three.

The One Physical Product That Makes Sleep Tracking Work Better
Every app on this list tracks sleep. None of them create the conditions for good sleep — that's the sound machine's job.
Hatch Rest Baby Sound Machine + Night Light
The Hatch Rest is the one I use and the one I'd tell any sleep-tracking parent to get first. Here's why it pairs so well with a sleep tracker: you control it from your phone without going into the room. You can turn it on, adjust the volume, change the sound — all without cracking the door and risking the wake. When you're watching your baby's sleep window in Huckleberry, you can set the sleep environment from the same phone.
It's also a toddler ok-to-wake clock when you're done with the newborn phase — one device from birth through preschool. We covered it in depth in our best white noise machines for babies → roundup if you want the full breakdown.

The Feeding + Sleep Connection (This Is What Most Parents Miss)
Every sleep tracker on this list helps you log when baby sleeps. None of them solve the problem that causes most nap failures in the first place: not knowing exactly when the wake window started.
Wake windows start from the end of the last feeding. A 10-week-old typically needs to go back down within 60 to 90 minutes of waking from a feed. If you don't know when that feed ended, you're estimating the window — and estimating means sometimes missing it.
This is where Mommy's Log fits alongside your sleep tracker. It logs every feeding with a precise timestamp — which side, how long, what time it ended — so you always know exactly when the wake window clock started. Pair the feeding data from Mommy's Log with sleep data from Huckleberry and you get the complete picture.
Mommy's Log is free, requires no account, and everything stays on your phone. The combination costs nothing beyond Huckleberry's subscription if you choose to pay for it.
If you want to understand wake windows in detail, our baby wake windows by age guide → covers the exact windows from birth to 6 months.
The Bottom Line
For most parents: start with Huckleberry free to see if you like the interface, and upgrade to the paid plan if the SweetSpot predictions appeal to you. If $9.99/month isn't in the budget, Baby Tracker by Amila covers sleep logging for free on any device.
Either way: pair your sleep tracker with a feeding tracker. The data is only half the picture without both.
