Happy Sad Face is an Android application that helps parents track their children's behavior. This app uses smiley faces as a graphical reinforcement so that small children can quickly identify their behavior. With this app, parents can track happy and sad faces for each child and can track from 1 to 5 faces for multiple children. All you need to do is tap on the face to change it from happy to sad or vice versa.

The free version of the app includes unlimited children, 1 to 5 faces per child, and the ability to assign different colors to each child. This app was originally designed for parents to track their young children's behavior, but it has now been re-imagined as a clever puzzle game. Some levels are very simple, while others are nearly maddening! If you think you can become a Happy Sad Face master, then this app is perfect for you.
