PiyoLog: Newborn Baby Tracker

Review by eFreeware

The most distinctive thing about PiyoLog is how much of a newborn's day it tries to hold in one place. Feeding, diapers, sleep, growth measurements, medicine, even a photo diary: the developer has built a single journal rather than a set of separate tools, and it's free to install. For parents who are tired of juggling one app for nursing and another for weight checks, that scope is the selling point.

It's a parenting app for the months when the questions come faster than the answers: how long since the last feed, how many wet diapers today, is the weight curve heading the right way. PiyoLog is made for keeping those answers in one running record, and for letting more than one person add to it.

I'd expect it to suit first-time parents especially, along with anyone sharing care with a partner, a nanny or a relative. The app reports over a million installs and a 4.9 average from more than 28,000 ratings, which suggests a lot of families have stuck with it through the newborn stage.

Feeding, diapers and sleep in one log

The core of the app is recording what happened and when. Nursing, formula, pumped breast milk, baby food and snacks are all separate entries, as are poop, pee and sleep, so a day builds up as a timeline rather than a set of disconnected notes. You can also log temperature, height, weight, baths, walks, coughing, rashes, vomiting, injuries, medicine and hospital visits, plus a diary entry with photos.

What appeals to me is the time bar: a daily view that shows the shape of the day at a glance. A night waking, a cluster of feeds, a long afternoon nap and a stretch with no diaper change all become visible without reading every entry. The app also totals the day automatically for things like nursing time, milk quantity and sleep, which is the kind of arithmetic nobody wants to do at 3 a.m.

The developer describes the layout as designed for one-handed operation, which matters when the other hand is holding a baby. I can't speak to how well that works in practice, but it's the right priority for this category. Reminders for the next nursing time are part of the package too, aimed at parents who want a nudge rather than a mental countdown.

Voice logging through Amazon Alexa is the feature I'd single out as unusual. If you have an Echo within reach, saying a feed or a diaper change out loud is a lower-friction way to keep the record going than reaching for a phone mid-task.

Sharing the record between caregivers

Childcare information is shared as it's entered, so a partner, nanny or other caregiver can look at the same record. The scenario the developer sketches is a father handling a feed while the mother is out, with the milk amounts appearing in her view as he logs them. That's a small feature in theory and a large one in a household where two people are trading shifts.

This is where the app earns its keep beyond simple note-taking. When care is split across people and hours, the handover is usually where information gets lost: who fed the baby last, how much, and how long ago. A shared log turns that into something you can check rather than something you have to remember to ask about.

It also means the record is only as good as the habit of entering it. Anyone who has tried to keep a paper log knows the discipline fades in the middle of a hard week, and a shared app makes that visible to everyone rather than just to you.

Patterns, charts and the growth curve

Beyond the day view, the app turns patterns across a week into graphs covering meals, sleep, bowel movements and temperature. I'd expect this to be most useful when something feels off and you want to know whether it's a one-day blip or a trend: fewer wet diapers than last week, sleep shifting later, a temperature that keeps reappearing.

The growth chart tracks height and weight, and the app stores milestone information month by month. That gives a pediatric appointment something concrete to look at instead of a vague account of how things have been going. The developer pitches it as a way to follow development week by week, which is the natural use for a chart like this.

None of this is analysis the app does for you. It shows the pattern; what the pattern means is still a conversation with your doctor. I'd treat the charts as a clearer memory of the past few weeks, not as a diagnosis.

What you need before you start

PiyoLog is free to install and available on Google Play. It carries ads and offers in-app purchases. No feature is tied to a purchase, so I'd go in expecting the ads as the trade for a free app and decide from there.

Voice logging requires Amazon Alexa. If you don't have an Alexa device, that part of the app simply won't be available to you.

There's also a Wear OS companion for smartwatches. From a watch you can log childcare records, check recent ones and use the breastfeeding timer, and a tile shows recent records without opening the app. That's a sensible fit for the moments when a phone is out of reach.

The app has been on Google Play since November 2017 and was last updated in September 2026 with a bug fix. That's a long run for a parenting app, and the update history suggests it's still being looked after rather than left to sit.

Families who will get the most from it

The clearest fit is a household with a newborn or young infant where more than one person does the feeding and changing. The shared record and the daily totals are built for exactly that arrangement, and the breadth of record types means you're unlikely to run out of places to put something.

It also suits parents who like having data to bring to appointments: weight, height, temperature and bowel movements all in one place, charted over time. If you're the sort of person who feels calmer with a written record, this is that record in app form.

Parents who prefer to keep things minimal, or who already have a routine that doesn't need tracking, will find the volume of options more than they want. The app is built around logging, and its value depends on how much you actually log.

A dependable logbook for the newborn months

PiyoLog does one job broadly: it keeps a complete, shared record of a baby's day and turns it into something you can look at. Feeding, diapers, sleep, growth, health notes and a photo diary all live in the same place, with daily totals and weekly charts on top. The Alexa voice logging and the Wear OS companion are the details that set it apart from a plain notebook.

The trade-offs are the ones that come with a free app: ads, in-app purchases, and a feature set wide enough that you'll ignore parts of it. Voice logging depends on having Alexa, and the charts are only as useful as the entries behind them.

For parents in the thick of the newborn stage, especially those sharing care with a partner or a nanny, I'd suggest giving it a try. It's free, the install base and rating suggest it holds up over months of use, and the shared log solves a problem that comes up every single day.
