Napper is the game-changing, award-winning app that uses data, science, and a little bit of algorithmic magic to predict your baby’s naps and bedtime - with almost uncanny accuracy.

Originally built by a dad on parental leave (still with us btw!) for him and his not-so-sleepy baby girl, Napper has now grown to help more than 100,000 families sleep better. So whatever issue you might be facing - short naps, frequent night-wakings, never-ending bedtime routines - there’s a good chance we can help you too.

→ Napper’s main features include…

• A personalized sleep schedule for your baby based on their natural sleep rhythms and research on infant sleep. The schedule adjusts as your baby's sleep needs change to promote healthy sleep habits and provide them with the restful sleep they need to grow and develop.

• User-friendly, straight-forward baby tracker to help you keep track of nursings, formula feedings, diaper changes and much more. You can also share your baby (and subscription) with as many caregivers as needed so everyone is on the same page.

• A large variety of sleep sounds, such as white noise, lullabies, and sounds of nature, that can be played in the background during naptime and bedtime. The sounds are carefully chosen to be gentle and calming, helping to create a peaceful and relaxing environment for your baby to sleep in.

• A comprehensive, science-based article series designed to help you establish healthy sleep habits for your baby. The course covers a wide range of topics, including the basic biological components of sleep, how to create a sleep-friendly environment and strategies for settling and soothing a fussy baby.

• Trends & statistics presented in easy-to-read charts that give you useful insights, such as the average amount of time your baby spends asleep, the number of night wakings, and the duration of feedings. Easily spot and identify patterns and trends in your baby's sleep, which allows you to make adjustments to their sleep routine as needed.

All in all, we’d really like to think that Napper is the most complete baby sleep app out there. But don't just take our word for it though - here’s what other parents have to say about it:

"Great app, helped me work out when nap times should be and helped set a bedtime routine! Definitely recommend."

"This is one of the apps which every mom or another caregiver should download straight away. Thanks to Napper I could develop a deeper understanding of my 4-months old sleep patterns. And now he falls asleep fast and without cries. Thank you!"

"I love Napper! I've used 4 other sleep tracking apps (paid for) and Napper has to be my favorite! I love the aesthetic of the layout and how accurate it is."

"This app is amazing!! Very accurate for my son and has been for months. Great features to select number of naps and set bed time if trying to create a routine too."

"My baby is 11 months and I use it all day every day. Keeps us on schedule"

"This app is really great, it's like a baby manual that comes with your child! I really love it."

"Really useful, I'm sleep deprived and can't remember exactly what time everything happens! The predictive sleep feature is great. Developers very responsive to feedback"

"I LOVE Napper! I have used lots of baby trackers over my 4 kids and this one is hands down my favorite."

"The app is pretty great but the customer service is even better! I thought I was locked out of my account and they contacted me and got me back in within minutes! This app has revolutionized how we care for our newborn."

"This is the app that got us through the 4 months sleep regression! And I love that multiple caretakers can add track baby's sleep. Such a great help!"

So don't let sleepless nights and exhausted days be the norm - try Napper (yes, today!!) and give your baby the gift of restful, peaceful sleep!

So helpful for sleep patterns

I’ve never written a review but my experience using Napper, as well as my customer service experience, have been exceptional. I’d been using two baby sleep apps for comparison, but Napper has out-performed the other (called Baby Naps). Napper allows me to track time spent nursing, diaper changes, medicine, naps, nighttime sleep and even night wakings. The predictive nap & sleep recommendations are extremely helpful, and rather than be prescriptive or static, the recommendations adjust according to when my baby sleeps, and for how long. (I imagine this is based on wake windows for the child’s age). I also really like the “nursing” module which has a stopwatch function and helps you record from which breast you fed from, and for how long. The logs are easy to edit and easy to access when you’re one-handed…When I wrote to their customer service team regarding a bug, Esper replied quickly with excellent feedback and was so helpful (thanks!). My husband and I are first time parents and really recommend trying Napper.

Almost perfect!

I am still in the trial period and I was hopeful it would be THE ONE for tracking my 3 week old’s sleep and nursing. Unfortunately, I really dislike the editing capabilities for nursing. If I pause a nursing session but don’t unpause right away when we restart, I can’t go back and edit that pause. So then if I try to edit the nursing time on the L or R side to correct the time, it won’t allow me to without completely deleting the pause, which then throws the whole nursing session off. Being able to note the time I restarted and edit the nursing session when my hands are free once again should really be made possible. Moms can’t always hit start immediately or should be able sometimes forget to for a fee minutes while still having the ability to have accurate time kept. That’s my only gripe with this app and since nursing is half of the reason I really use this tracker, it’s a big deal for me. For that reason, I probably won’t even complete the trial period, but I wish I could! The sleep tracking is awesome but if I’m paying for an app I need to be able to track his nursing in the same place. — if the app developers change this I would totally recommend and would purchase it!

Good for sleep, not so good for tracking

The app is good, it’s spot on with the timing for naps. It’s not magic, our baby still wakes up many times through the night but is understandable as babies go through many things that will make their sleep challenging. I’m giving two stars not because the sleep tracking but because of the bugs and interface. - I love the graph that shows the day and night ahead but you make the effort of tracking everything and then the nice interface disappear and you can’t see how the night went again with the nice graph and only with the historical one which is awful. The sleep is split in two days and so hard to know what is for what night. - Tracking night wakings and things in general is difficult when you or your partner did it and you’re out of sync. You end up duplicating or missing things. - It’s also a mess using the widgets again keeping them in sync with your partner's. Most of the time they’re not up to date and you know the baby was put to sleep and he has a night waking you use the widget and it is not the waking what you did but another sleep and the app accepts it without complaining. - is not clear what you’ll do when clicking the widget. I’ll give 5 stars when those issues are fixed, but those are pretty big issues for me.

Hi Donflopez, thank you for using Napper and for reaching out to us with your feedback. ✨ Just like you describe Napper switches to day mode after you have logged the wake up in the morning. And when you log bedtime in the evening Napper switches to night mode. Great feedback, we really appreciate it and I will bring it up with the team. If you have more ideas on how we could make Napper more user friendly we would love to hear them! Thank tou for informing us about the issue with the widget, I will bring it up with the rest of the team. We really apologise for the inconvenience!

It can be good to double check that all caregivers are using the latest version of Napper, maybe one of you needs to update the app? Sometimes using different versions can create issues with the synchronization.

Please email me at if you have any questions or more suggestions on how we could make Napper better. 😊

Best regards,
Emma, Napper 🍼
