About

Chippy App

Features
Read full description

Chippy is an educational scavenger hunt through the human skeleton. Built to use NFC tags attached to a human skeleton - or even a kid’s clothes at school - the app pops up names of bones and the user is meant to find that bone on the human body, tap the corresponding NFC tag, and find out if they’re right or wrong. Chippy is also built in such a way that the nature of the scavenger hunt or tapping quiz can be replaced with a completely different quiz by replacing the StartURL from the app’s Settings screen. Chippy is exclusively fun and educational. It is 100% free with no in-app purchases or advertising and gathers absolutely no data about users whatsoever.
