Napper vs Baby Daybook

Pick Napper if sleep is the whole problem and you'll pay for personal nap predictions, sleep sounds, and a sleep course. Pick Baby Daybook if you want one app that logs feeds, diapers, sleep, and health for free, with a next-nap prediction thrown in.

The catch flips between them. Napper's free version only logs sleep, but sharing with caregivers is part of the deal. Baby Daybook lets you log almost everything for free, but syncing with a partner needs Premium.

Which one should you pick?

Pick Napper if

nap timing is what keeps you up at night. You want predictions built from your own baby's sleep, a daily schedule, sleep sounds, and a course, and you're fine paying for a plan.

Pick Baby Daybook if

you want feeds, diapers, pumping, sleep, growth, teething, and medicine in one app. Logging is free, the watch apps and widgets are free, and Premium has a lifetime option.

Or try Tiny Baby Tracker if

you mostly need the daily log of feeds, diapers, sleep, and pumping, and want every caregiver on it for free. It has no sleep predictions.

The biggest differences between Napper and Baby Daybook

What the free version lets you log

Napper's free version covers daily sleep tracking and an age-based schedule. Its pricing page puts other tracking categories on the paid plan, and several App Store reviews say you can't log a diaper change without paying. Baby Daybook's free version has unlimited logging of feeds, diapers, sleep, and more, with a limited window of history.

How good the sleep features are

Both predict naps. Napper is built around it, with personal nap and bedtime predictions, more than 30 sleep sounds, and a sleep course on its paid plan. Many App Store reviews call its timing spot on, though some reviews say predictions stopped fitting their baby. Baby Daybook shows the next predicted nap for free from 2 months, and the full day on Premium.

Who pays for sharing

Napper lets you share your baby, and your subscription, with as many caregivers as you need. Baby Daybook puts Family sync on Premium, and one purchase covers everyone on the shared baby profile. So with either app, a two-parent log means someone pays.

Price model

Napper's App Store plans start at $14.99 a month, with yearly options, and its website lists a $69.99 yearly plan. Baby Daybook's US App Store prices vary a lot, from $1.99 to $9.99 a month, with yearly plans and a $99.99 lifetime purchase. Baby Daybook's Android version is labeled as containing ads.

Getting your data out

User reviews say Napper has no export in the app, and its privacy policy says you can ask for your data by email. Baby Daybook Premium can export to PDF, including growth, teething, and vaccine tables.

Which app is better for sharing with my partner?

Both charge for it in a way. Napper's subscription covers as many caregivers as you need, and Baby Daybook's Premium covers everyone on the shared baby profile. If you'd rather not pay, Tiny Baby Tracker shares the log free, though it doesn't predict naps.

Which has better watch apps?

Baby Daybook has free Apple Watch and Wear OS apps with complications and tiles. Napper has an Apple Watch app. Napper on Wear OS is not listed.

Can I use Napper and Baby Daybook together?
