## What is Diaper Calc?

As a father, I have struggled every time we needed a new pack of diapers: "Which package should I buy?", "Can I buy directly a bigger pack or is my baby already outgrowing the current diaper size?"
These were the questions I asked myself constantly and that is why I have created this app. 

DiaperCalc is a simple but useful utility for parents that counts how many disposable diapers do you need to have in a specified period of time. The computation is based on the baby current weight and expected baby growth based on percentile curves of pediatric growth charts.

Main features:
•  Computes diaper count and sizes for the selected period of time (up to 3 years of age)
•  Recommends which packaging is ideal to purchase
•  Displays chart with expected baby growth
•  Available to distinguish US and EU diaper sizes
•  Usable for more than one child
•  Contains useful tips related to diapers purchases and pre-stocking
•  Works offline
•  Light/Dark mode support

Enjoy the app and do not hesitate to share your feedback with me!
