There's a new parenting app on the block that enables parents to analyze, track, and promote their child's development through their smartphone. It is recommended for parents with children aged up to 5 years old and has been developed with paediatricians from Stanford and USCF.
When you first install the app and set it up, it asks for baby's name and date of birth, as well as if they were 3 weeks or more premature. It then goes on to an assessment of baby's reactions so it can analyse it and give you a rough estimation of wether your child is on track for their age.
To create the developmental age, there is 5 categories it uses.. Gross motor, Fine motor, Self help, Language and Social. The app is free to download originally and the self help and language categories are free but to access the others, you do need to go premium which you can buy monthly for $4.99 or yearly for $42.99.
