Here is a smart stadiometer that allows parents to monitor their children’ height and compare it to CDC growth charts. The InBody PUSH has an ultrasound sensor to measure your height. It also displays humidity and temperature. The app is compatible with iOS and Android devices and shows all growth milestones.
You can use this device for users up to 6’7″, so it works for adults too. The app lets you register up to 20 individuals from age 3 to 20.[where to find more info]
