Do yourself a favor: get this app!
I downloaded this app and absolutely love it! If you have any interest in ancient Mesoamerica at all or even mildly curious about the great civilizations that flourished there, you will enjoy this app! It has many great features and all parts of it run flawlessly! Be sure you also find the virtual replicas of the ancient, stone masks found there and use the feature to take a selfie of yourself wearing one and send it to your friends and family! Five Star App !!!
