naido forecasts naps from your baby’s own rhythm and shows you an honest window instead of a fake minute. It runs entirely on your phone — no account, no cloud, no one watching.
Switching from Napper or Huckleberry? Bring your history. It works from day one.
Napper, Huckleberry, Baby Daybook, Baby Buddy — or any CSV. On iPhone: the encrypted web app works today, an App Store version is in the works.
Coming from another app? Every other app makes you start from zero — one or two weeks of logging before the predictions mean anything. naido imports what you already have: Napper and Huckleberry CSV, Baby Daybook, Baby Buddy, or any CSV with a column mapper.
Then it shows you something no other app will: how well it would have predicted your baby’s naps over the last months. That number is yours before you’ve paid anything.
Sleep apps need your child’s entries in order to predict anything. The only question is where those entries end up.

The sync between your devices is encrypted. We couldn’t read your child’s entries even if we wanted to, and we have nothing we could hand over on request.
Other apps send the sleep times to a server that computes the prediction. With naido the phone does the maths. It works with no connection at all.
The family code is the family. Partner, grandparents and childminder join without anyone needing a second subscription.
Figures as of 03.09.2026. Based on the providers’ own public information: privacy policies, App Store privacy labels, Google Play data-safety disclosures and the respective vendor sites. Prices in US dollars are quoted that way by the providers themselves; the euro figure beside them is an approximate conversion, not an amount charged. Baby Daybook lists several yearly prices in parallel; the cheapest one found is shown. We update this overview when the figures change and welcome corrections.
A baby is not a clock. We tested the clever models — machine learning, sleep-science formulas — on nine months of real data. A simple estimate built from your baby’s last few days beat all of them, because a baby changes faster than a model can learn.
So naido shows a window sized to your child’s own variability. In four out of five cases, the nap starts inside it. And when you spot the first yawn, one tap on “getting tired” beats every calculation — that’s new information, not old information recomputed.
Everything naido knows lives in an encrypted database on your device. There’s no account to create and no server we could look at. Export your data whenever you like.
Tracking with your partner? Pair the phones with a QR code. They sync through a mailbox only your devices can open — we run it, we can’t read it. At home on the same Wi-Fi, they don’t even need the mailbox.
