Android App Recommendations

I just wanted to see if anyone had found any apps that helped with educating your child.  I found one called “VanGogh Painting” that shows some of his works and you can set them as your wallpaper.  Another is called “Leonard Da Vinci Puzzle” and you see a picture of one of his paintings and then you put a puzzle together of that picture.  Another one was called “Painting Finding” and it will take a painting and you have to find the differences.  But you would need to use some discretion as I had a print that had some nudity.  So I will not let my young children be using that.

Have you found any apps that you use?
