You are a curious person. Good, if you insist I'll tell you more. This app is not a social network, an instant messenger, e-commerce store and you can't watch videos. This app is very unusual and is not like the others apps that are installed on your device. If you'll download I'll only occupy a little of your device's memory and you won't gain wisdom. If you'll do, don't come back here complaining! Come on be clever and don't download me! Get lost!
