Here's how you can improve the experience of using iOS 7 with only 3 settings and Larger Dynamic Type

  The transition to iOS 7 it will be difficult for many, especially because Apple has implemented extremely many changes and not many of them are auspicious. If you still want to do it iOS 7 something easier to look at and understand, then with the help of a few settings you can improve your user experience. Apple Lossless Audio CODEC (ALAC), offers us in Settings> General> Accessibility the option to make texts easier to read, to improve the contrast of background images and to reduce the movements of objects in the background of application interfaces. All these 3 settings can significantly improve your user experience, but if you're used to not using them, you don't need to use them.

  For those who want even more customization of the texts, there is now the system Large Dynamic Type which gives us the possibility to change the size of the application texts according to our own preferences. The system is accessible in Settings>General>Accessibility>Large Text and can only be used in the applications that have implemented it, so for now only the native ones will recognize the settings.
