With kids today being so technologically driven, some even have a better understanding of tech than us adults! Take that boring paper chart down off the fridge and introduce your child to this new, stylish and vibrant app. Whether it is learning a new skill (like playing the piano) or a simple part of a daily routine (brushing your teeth) or making challenging parts of their development easier (potty training). Star Chart can help you, help them :) Main Features Creating a personalised star chart for your child with the option to add more! Assign tasks for your child to complete on a daily or weekly basis!
