Smart devices have become so powerful in recent years that they have become our central tool for work, study and entertainment. We use them to take photos, edit videos and pictures, write texts, manage finances, help each other with navigation, play games, shop, chat with loved ones, connect with like-minded people, watch movies, listen to music, train and many other things. A lot of credit for this goes to the various applications and their developers who make these various functions and services possible.
