Power to parenting! Reward charts are a proven and fun way to reinforce good behaviour in your children. Not only can positive behaviour be reinforced, reward charts can help deter negative behaviour as well! Star Chart takes a familiar form and layout and brings it into the modern age. 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! Choose from our selection of tasks or customise and make your own! Give them a reward so your child is determined to complete their tasks and boost their motivation!

You can create a chart with tasks by following these simple steps: Click the add icon to create a new chart. Choose a name and icon for your chart. Open your chart and click on the add tasks button where you can manage tasks and add them onto your chart or remove them when it is no longer needed. Once you have added your chosen tasks, you can click on a star for each day of the week per task. Hold a star again to remove it. Set a goal number of stars to reach and a reward for completing it.
