In this educational app for kids, the objective is to learn and count to 100. You will learn to count by 2’s, 3’s, 4’s, 5’s, and 10’s, and even recognize counting patterns

You can also set the number of missing numbers in the hundred chart. The app has different levels that you can choose from (Easy, Medium, Hard).
