Great beginner to medium chess app

Ive played chess when I was a kid through high school. My son recently wanted to learn chess. We started playing a wanted to see what was out there for apps to help both of us.
This is a great app. From quick and easy rules of the game. Visual aid on how the pieces move and being able to adjust the difficulty level.
Highly recommend.
The graphics are basic but what you get for versatility not even a issue.
