The Baby Tracker is a free module in the Hubble connected app where you can record all the baby's developments to help you monitor their growth. You can enter growth measurements such as weight, height, and head circumference and have them as charts. The feeding tracker allows you to record the type of food, volume, time, and date. The diaper change tracker allows you to record the time, date, and contents, while there is also a sleep duration tracker for both day and night.
It also provides you with sleep tips as well as general tips for the baby's development.
