Onoco alternatives with free nap prediction
Onoco is a baby tracker whose free plan has unlimited tracking, pattern charts and free invites for unlimited caregivers, plus an Apple Watch app. Its Optimal Nap Time Predictions are in Premium, and its premium page shows £12.99 per month (check the page for your country). Pixy is the reverse: the nap prediction is free with no trial, while sharing with a partner is paid. If the prediction matters more to you than free sharing, that is the difference.

What Onoco offers
Onoco is a London-made baby tracker, and its free plan is generous. Its premium page says the free plan “will always be free” and lists unlimited tracking, advanced pattern charts, data analysis, activity reminders, milestones, photo sharing and an Apple Watch app. Caregiver sharing is free for all users: you can invite unlimited caregivers with customisable access levels. Its App Store listing shows 4.7 from 473 ratings, a longer record than Pixy has. It offers English and three more languages. Pixy cannot match that on free sharing.
The prediction is the paid part. Onoco Premium adds Optimal Nap Time Predictions, a daily routine creator, schedule suggestions, custom logs, a family calendar and CSV data export. Its premium page shows £12.99 per month; check the page for your country, because the other prices and any trial are not stated there. It is on iPhone (the listing says iPhone only on iOS) and Android. Its page covers 460+ developmental milestones over the first five years; the age range for tracking, and whether it has home-screen widgets, its page does not say.

Which one, and for whom
- Onoco, if free sharing with several caregivers matters most, you want an Apple Watch app, or you prefer an app with a longer record and many ratings.
- Pixy, if you want a free nap prediction without a trial clock, would like to try the AI tools within a free allowance, or want one app with 15 languages that carries on to age twelve. Expect to pay if you want to share with a partner.
The full comparison puts seven apps side by side, this guide covers which apps predict sleep for free, and this one how two parents can log together.

General information, not medical advice. Every child develops on their own timeline and the ranges here are typical, not targets. Pixy is a tracking tool, not a medical device. For anything about your child’s health, ask your paediatrician or health visitor.
Track it instead of remembering it
Pixy logs sleep, feeds and routines from newborn to age 12, and predicts the next nap from your child’s own wake windows. That part is free.
