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.

The best app!!!!

I LOVE Napper! I have used lots of baby trackers over my 4 kids and this one is hands down my favorite. I love the UI, it is beautiful to look at and easy to use. I love the predictions for the next sleep time and how it lays out the day for me so I can keep the times loose in my schedule for when baby needs a nap or to start bedtime. I love how the app can differentiate between a night waking and waking up fully, the other apps could not and I would often have skewed data for sleep times. I forgot to set the timer for a nap the other day and Napper notified me baby’s nap was late and asked if I forgot to set the timer! I have never encountered such a smart app. 10/10 would recommend to anyone looking to track sleep, nursing, diaper changes, etc.

No edit option after midnight

Edited to address the developer feedback to be clear. Unable to use any longer without paying, so I can’t further explore how it could possibly be edited. But I tried many times in the history tab to much frustration - and I think I’m a relatively tech savvy person. From what I could see you are able to edit entries, but for example if your baby falls asleep for the night at 11:55pm but you don’t add until 12am, you are unable to go into the history tab and add that they fell asleep for the night at that time (again from what I could figure out). You can edit for example a specific nap entry. But when you click the add button, and enter a time in the past day, it believes you mean the future and gives an error. Highly suggest adding a date feature in with the time to make everything more easily editable in the past.

OP: Loved this in real time, but honestly who can remember to mark every single thing the second it happens? Once midnight rolls around there seems to be zero ability to go to the day before and mark when your child went to sleep. We are parents, sleep doesn’t reset at midnight. So confused by this!

Hi again jesiqueiros,

Thanks for clarifying! You should be able to swipe between the dates on the History screen and achieve what you're trying to do. Please let me know if that still doesn't do the trick. We're also always trying to improve the UX though - so thanks for your feedback and letting us know that this was an issue for you! We'll see what we can do to simplify things 🙌

Please do also send us an email to if you have more feedback, or need any further assistance with this! It's a bit slow to talk through the App Store since Apple has to review every post :)

Wish you a great week!

Hi jesiqueiros,

Thanks for getting in touch! Of course you can add things on the day before! Just go to the History tab and you can add whatever you want to, whenever you want to from there :)

Please send us an email to if you need any further assistance!

Kind regards,
