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!
