The text discusses how much text is used in the first screens of popular iOS apps, with a surprising finding that about 36% of these screens are dedicated to displaying text. The author studied 25 popular apps and found that this percentage ranges from just 3.5% for Snapchat to 57.5% for Ticketmaster. The study also reveals that different types of apps use varying amounts of text, with social media apps reserving most of their interfaces for sharing personal video or images instead of text. The author argues that the right amount of text to show in an app screen is around 30-40%, and suggests that developers should prioritize clear and concise communication over visual design elements. The study's findings have implications for app design, highlighting the importance of language as a fundamental element of user experience.
