Your child's data stays yours
Everything the night actually needs
Nesty was designed around one sentence: 3am, one hand, logged in two taps.
Two taps, then back to bed
Feed, sleep and diaper are one tile each, low on the screen where your thumb already rests, on a dark surface that does not light up the room.
Feeding, timed the way feeding goes
Left and right are separate timers. Pause one, start the other, come back to the first. Put the phone down and both sides pause on their own. Bottles go in as ml or oz, and a combo feed keeps breast time and bottle volume on one entry.
A sleep session that crosses midnight
Start a nap or a night sleep and it runs until you stop it — through the small hours and through a restart. In the morning the start time is the real one.
When the next nap is likely
Nesty takes your child's age and the time they last woke, applies the wake window typical at that age, and puts the next likely nap on the home screen with a quiet notification ahead of it.
Growth on the WHO curves
Height and weight are plotted against the WHO Child Growth Standards for boys or girls, in kg and cm or lb and in, so you can read the trend at home days before the appointment.
Written to the device first
On a plane, in an underground car park, in a nursery with one bar of signal: the entry is saved on the phone and sent when the connection returns — and Nesty tells you plainly when something is still only on this phone.
The nap and feed cards are average guidance from typical wake windows — not a diagnosis. Talk to your pediatrician about your child's health.
The handover card
The end of “has she eaten yet?”
The top of the home screen answers what everyone actually asks: when the last feed was and what it was, how long the last sleep ran and when it ended, plus the initials of whoever logged them. Two lines, no scrolling, no arithmetic at 3am.
- Everyone gets their own account — there is no shared login
- Invite by link or QR code: it works once and expires after 72 hours
- Every entry carries the name of the person who made it
- Entries reach the other phones within seconds
Growth & reports
Walk into the appointment already knowing
Height and weight sit on the WHO Child Growth Standards for boys or girls, in metric or imperial, so the percentile is a trend you read at home rather than a number you hear in the waiting room.
Then choose 7, 14 or 30 days — or any range you like — and export a clean PDF: total feeds, bottle volume, sleep sessions, total sleep, diaper changes and the latest measurement. The same range exports as CSV. Weekly sleep, weekly feeds and weekly diaper changes each come with a daily average, so a hard week is something you can see instead of something you argue about.
Wrist & home screen
Log it before you put the phone down
Apple Watch and Galaxy Watch log a feed, a sleep or a diaper from the wrist, and anything logged out of range syncs itself later. The home screen widget shows the last entry at a glance — a tap opens the right screen.
How it works
Four steps, and the fourth one is for the pediatrician.
Add your child
Name, birthday, and whether you work in metric or imperial. That is the whole setup.
Log with two taps
Feed, sleep and diaper sit under your thumb — in the dark, with one hand, offline.
Invite your family
A partner, a grandparent or a sitter gets their own account from a link or a QR code.
Take the PDF to the checkup
Pick 7, 14 or 30 days — or any range — and export a clean summary for the pediatrician.

Nesty support
Questions, bug reports, account deletion, anything at all — write to a human at official@eodin.app.
- What is Nesty?
- A baby and child tracker for ages 0 to 7. It logs feeds, sleep, diapers and growth, predicts the next likely nap from age-typical wake windows, and shares every entry with the caregivers you invite.
- Which devices does it run on?
- iPhone and Android phones, with a home screen widget on both, plus Apple Watch and Galaxy Watch apps. Download it from the App Store or Google Play.
- Does everyone in the family need their own account?
- Yes, and that is deliberate — there is no shared login. You invite a partner, a grandparent or a sitter with a link or a QR code that works once and expires after 72 hours, and from then on every entry carries the name of whoever made it.
- Does it work without a connection?
- Yes. Entries are written to the device first and sync on their own once you are back online. Nesty shows you plainly when something is still only on this phone.
- Is the nap prediction medical advice?
- No. It is average guidance: the wake window that is typical at your child's age, applied to the time they last woke. Nesty supports your parenting, it does not replace your pediatrician.
- What happens to my child's data?
- Health entries about your child are never sold. Only the people you invite can see them, and you can delete your account and everything in it from inside the app.
- How do I get help?
- Email official@eodin.app and a human answers — in English or Korean. Tell us the device, the app version from Settings, and what you were doing when it went wrong.
