About PiyoLog: Newborn Baby Tracker
PiyoLog - Newborn Baby Tracker works with Amazon Alexa and can be recorded by voice.
No more need to have several child care apps: PiyoLog is an all-in-one digital baby journal where you can log the most important information in your post pregnancy period.
* Baby breastfeeding tracker
* Pumping tracker
* Baby feed timer
* Baby eating and diaper tracker
* Baby growth tracker
Thanks to the variety of functions, PiyoLog baby tracker makes postpartum life much easier. Whether it’s baby food or sleep, height, weight or medical conditions, the app will store baby nursing info as well as baby milestones month to month.
◆Built-in sharing function◆
Childcare info is shared immediately, so both parents, nanny, or caregiver can check on the baby's records anytime. On days when daddy is taking care of the baby while mommy is out, mommy can still have peace of mind by checking the baby eating tracker and milk amounts when daddy records them.
◆Record types◆
Nursing, Formula, Pumped breast milk, Baby food, Snacks, Poop, Pee, Sleep, Temperature, Height, Weight, Baths, Walks, Coughing, Rashes, Vomiting, Injuries, Medicine, Hospitals, and any other information you like, as well as a childcare diary (with photos)

It’s not easy to grow a baby. But having PiyoLog as a post pregnancy companion and newborn tracker makes parenting more organized and thus less stressful. Once you start keeping a child journal and log all developmental milestones, you’ll find how simple it’s to nurture your infant and share important details between parents.
Check the baby food tracker to see what your newborn eats at this particular stage and how s/he reacts to this food. Consult their nap tracker to find out when they need to sleep. Look through the pump log to know exactly when it’s time to get milk. Add your baby’s age, height, weight to the milestone tracker and observe the infant development week by week.
Create the best nursing routine with PiyoLog daily baby tracker! Accurate records = less stress = happy parenting. Track and grow a healthy baby!
