Breastfeeding tracker Pump log

Review by eFreeware

Erby is a baby tracker for Android from Demapps LLC, filed under Parenting. It is built around a simple diary idea: instead of trying to remember when the last feed was or which side you used, you record each event as it happens and let the app keep the history. Breastfeeding, pumping, sleep, diapers, health notes and growth are all tracked in one place.

The reason to consider it is the breadth of that record. A single log can hold feeding sessions, expressed milk, sleep patterns, diaper changes and medical notes, and it is designed to be kept for more than one child. For parents who want one timeline rather than several separate notes, that combination is the main draw.

It is free to install and supported by ads, with a Premium version available through in-app purchases. The app has been on Google Play since December 2020 and shows a 4.8 average from 22,900 ratings, with more than a million installs. The most recent update, in October 2026, was described as bug fixes and performance improvements.

The feeding timer at the center

Breastfeeding is the feature the developer leads with, and the design is deliberately quick: you start the timer with one click at the beginning of a session. From there the app tracks how long the feed lasts. It also remembers which breast you used last time, which is meant to help you alternate sides and avoid lactostasis.

Pumping is handled separately. You can run a timer for each breast on its own or for both at the same time, and record the volume of milk you express. The app also keeps a record of frozen milk, so you can see how much you have stored rather than guessing from memory.

There is a food diary side to this as well. Food, drinks, medications and supplements can be entered for the baby and for the nursing mother, with the aim of spotting allergic reactions in the infant. It also mentions recording responses to first complementary foods, so the feeding picture extends beyond milk.

Sleep, diapers and the rest of the day

Sleep gets its own tracker with a timer, and the app distinguishes night sleep from day sleep. The point is to build a picture of when your child is awake and asleep, which can be useful when you are trying to understand wake patterns rather than just survive them.

For diapers, you log urination and bowel movements separately, with the option to note volume when it matters. The developer presents this as a way to keep an eye on hydration and to plan how many diapers you need. It is a small feature, but it feeds the same timeline as everything else.

Health records cover symptoms, temperature, vitamins, medicines and vaccinations. Growth is tracked through weight gain and the app also notes teething. The developer suggests this makes the app useful when visiting a pediatrician, since the history is already assembled.

Activities round out the log: bathing, walks, tummy time, games and massage. None of these are complicated on their own, but together with feeding and sleep they give a fuller account of the day than a feeding timer alone would.

Statistics, history and reminders

Everything you enter builds into statistics and a history of events. You can filter that history by type, so you can look at only walks or only the pump log, and the developer frames the statistics as a way to spot trends and adjust care if something looks off.

The app includes reminders. They can be set for the events you care about, which helps avoid missing medication or forgetting a feed or bedtime. That is a practical addition for anyone running on broken sleep.

The Premium version extends this. It adds reminders for an exact date and time, with the ability to switch off recurring reminders at night, and full access to statistics, including the daily routine for all time. Premium also brings syncing and restoring recordings across multiple devices, customizable widgets on the main page, and export of data to Excel for analysis or printing. Teeth records and an ad-free experience are Premium features as well.

What it asks of you

The app is free to download and supported by ads, and it offers in-app purchases for the Premium version, which is where the full set of features sits.

It also asks for consistency. A tracker only reflects what you put into it, and the value comes from recording daily activities and feeding statistics over time. Parents who log diligently will get more from the statistics and history than those who enter a feed here and there.

There is a stated scope, too: the developer describes the app as helping parents keep track of a baby's progress up to one-year-old. If you are looking for something beyond that first year, this is not the frame it is built around. It supports a diary for multiple children and is suitable for twins, so a second baby does not mean starting over.

Getting the most from the diary

The one-click feeding timer is worth using from the start. If you begin the timer when a feed begins rather than reconstructing it afterward, the duration and side data stay accurate, and the app's memory of the last breast used does the work for you.

The mother's food, drink and medication entries are easy to overlook, but they are what make the allergy-spotting idea possible. Logging them alongside the baby's reactions gives you something to compare against when a rash or a restless night appears.

If you are tracking growth, weight and teething, those entries pair naturally with pediatrician visits. Having the history filtered and ready is more useful than trying to recall dates in the waiting room. For anyone juggling more than one child, keeping a separate diary per child from the beginning avoids mixing records later.

On a Wear OS watch, the app provides a Tile for quick launching. That matters more than it sounds when your hands are full, since reaching the timer quickly is the difference between a logged feed and a forgotten one.

A detailed log for the first year

Erby is a well-rounded baby tracker for parents who want a written record of the first year rather than a single-purpose timer. Feeding, pumping, sleep, diapers, health and activities all live in the same diary, and the statistics and filterable history turn those entries into something you can actually look back at.

The trade-offs are straightforward. It is free with ads and in-app purchases, and the Premium tier is where syncing across devices, Excel export, widgets, detailed reminders and an ad-free experience sit. The app is also framed around the baby's first year, and it rewards regular logging rather than occasional use.

If you are expecting a baby or in the middle of the newborn months and want one place to record feeds, sleep and health notes, this is built for exactly that. Parents of twins or those planning to track a second child later will find the multi-child diary useful. It is the kind of app that pays you back in proportion to how consistently you use it.
