iOS 13 introduces several new features including dark mode, improved maps, an updated Siri, emoji search, and an improved reminders app. Dark mode provides a system-wide dark theme that is easier on eyes and can help save battery life. Maps has been updated with more accurate addresses and road coverage based on 4 million miles of Apple mapping. Siri has been upgraded with a new voice using neural text-to-speech. Emoji search makes it easier to find emojis and Memoji customization is now available on all compatible iPhones. The reminders app also receives an updated interface aimed to be less confusing.
