Spotify updated its iOS app today with support for iPhone X, exactly two weeks since Apple's latest smartphone launched. The update removes the letterboxing of Spotify's interface on the iPhone X's 5.8-inch OLED display, which should come as welcome news to heavy users of the app, allowing them to see more of track lists and search results on the screen, and more artwork when browsing albums and playlists.
The music streaming service is unusually late to the game on this front, with many top App Store apps already having updated their interfaces for the iPhone's 1,125 × 2,436 resolution display, which results in roughly 20 percent additional vertical space for content compared to the 4.7-inch displays of the iPhone 6, 7, and 8.
Apple was naturally quick to publish human interface guidelines for developers coding iPhone X apps. The documentation explains the changes that need to be made to ensure apps make the most of the additional space. At the same time, the guidance warns developers away from encroaching on certain areas of the screen, including the rounded corners, sensor housing, and indicator for accessing the Home screen.
