Research initiative Precision Driven Health is developing a smartphone-enabled electronic babies' and children's growth chart that is adapted for New Zealand's diverse population, in a bid to help tackle rates of childhood obesity.

Led by Gayl Humphrey, the joint lead for the health informatics and technology program at the University of Auckland's National Institute for Health Innovation (NIHI), the project aims to build a tool that gives parents an easy way of visualising the development of their child and what standard measurements mean.
