Germ buster is a robot who detects germs with the voice of my 3 year old daughter. Every kid who has tried this app has immediately gone to wash their hands.

The app asks you to take a picture of your hands, and then uses image overlay technology to animate some friendly germs over the picture of the hands.

After the kid has washed their hands, germ buster will ask if the hands have been washed. If they have, then no germs are found and you are given 3 prizes.
