Joni

Your baby's data stays on your phone — always.

A calmer way to track sleep, feeds, and diapers

Joni helps you see your baby's day at a glance — with gentle reminders when time blurs together.

All your data stays on your device. We do not collect, upload, or store any of it.

Coming soon to the App Store and Google Play.

Your data stays on your device

Sleep logs, feeds, diaper changes, and your baby's profile are stored only on your phone. Joni has no servers that receive your care data. We do not create accounts, do not sync to the cloud, and do not sell or share your information. If you export a CSV, you choose where it goes.

No cloud upload

Your logs are never sent to us

No account required

Nothing to sign up for or log into

No data collection

We do not collect or store your baby's information

Optional feed reminders are scheduled on your phone too — we don't need your data to nudge you.

On your device only

We don't collect or store your data — it never leaves your phone

Built for tired nights

Big buttons, quick logging, optional feed reminders

Yours to share

Export a CSV anytime — only when you choose

Everything you need, nothing you don't

Simple tools for sleep, feeds, and diapers — designed for tired nights and busy days.

Track sleep

Start a timer for naps and nighttime sleep. See how long your baby rested and what happened last — without digging through menus.

Log feeds

Record breast, bottle, and solid feeds in a few taps. Notes and timestamps stay in one timeline you can scroll when the days blur together.

Diaper changes

Log wet, dirty, or both — alongside feeds and sleep so you have a full picture of the day.

Your dashboard

A gentle morning (or midnight) overview: last sleep, last feed, recent activity, and — when you have enough history — predictions for what might come next.

Gentle reminders

Optional notifications about three hours after a feed, for those moments when you lose track of time. You stay in control — turn them on or off anytime.

Export your data

One tap to export sleep, feeding, and diaper logs as CSV. Share a week with your pediatrician or keep your own backup.

    Dashboard summaries and predictions build from your own logs — processed locally, not on our servers.

A gentle overview of your day

Made for the early months

The newborn stage is beautiful and exhausting. You do not need another complicated app or another login to remember. Joni is intentionally simple: track what matters, see it clearly, and keep it private. Whether you are breastfeeding, bottle-feeding, or mixing both, Joni fits around your routine — not the other way around.

  • Your baby's data stays on your phone — we don't collect or store any of it
