Apps are the itty bitty larval form of apples, analogous to peas. They grow in iPhones and fall out once they ripen into true apples. They hatch out of a specialized farm called an App Store and come in many flavours and surprises, from the addictive YouTube to the stealthy Fruit Ninja. The iPhone, as a grove, is very competitive, and apps of all types come and go. One of the most iconic critically endangered breeds is Angry Birds, who have seen brutal competition with the likes of Clash Royale.
