Have you ever heard about sleep pressure, wake windows, and the circadian rhythm? If not, those are some of the pillar stones of (baby) sleep!

Napper helps you find your child's natural rhythm and creates a daily schedule based on that rhythm so that you'll always put your baby down at the perfect time.


Tailor-Made Sleep Schedule

Napper provides a suggested sleep schedule using the latest scientific recommendations and your baby’s own, natural rhythm to help you understand sleep pressure and find the perfect time to put them down.

Baby Sleep Tracker & Daily Statistics

To help you keep track of your baby's sleep, enter their naps and bedtime sleeps in your log and get unprecedented personalized insights. It's easy to use, provides effective insights, and is fun to see your progress!


Looking back at your day and jotting down some notes can help you cope with stress, help to get to know yourself better and pave the way for you to know how to resolve disagreements you may have with your partner or kids.

Further, Napper Unlimited (paid membership) gives access to:

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.

So Freaking Accurate!

I LOVE this app! It pinpoints my daughter’s sleep patterns to within a few minutes and has made sleep training SO much more easy.

I also really like being able to add medicine, feeding, and diaper changes. I don’t really use the feeding or diaper change logs so much unless I suspect a problem, but being able to keep track of when I last gave her infant Tylenol is super helpful to prevent overdosage.

Now the issues I have are you can’t add a medicine log if you have an active sleep log (like I put her down for bed, but she hasn’t fallen asleep yet). That’s just kind of dumb. Or, you can’t log a diaper change and then the start of bedtime. You literally have to wait a minute. Please fix this, guys.

What I would really like to see in future updates is Siri and Apple Watch integration. So, for instance, if I’m driving and she falls asleep, saying “Hey Siri, Nap Time “ and it logs a nap. Or “Hey Siri, End Nap” and the nap log ends. And have a quick button on the Apple Watch to log a nap or whatnot. These integrations would make my life sooo much easier!

Overall, this is an amazing app and I can’t recommend it enough.

Hi there Lerandia,

Thank you SO much for this wonderful review - it means the world to us that you love Napper and that it’s working so well for you 🙏❤️❤️❤️

Regarding your suggestions - I love them and we are actually already working on fixing some of them (agree that it’s totally stupid that you can’t track two things at once). Watch app is something we want do do soon as well!

If you have any more questions or ideas for improvement, send me an email to and I’ll make sure we have a look at it ASAP!

Wish you a great weekend!

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!

Developer Response ,

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,
