Korean apps unveil iPhone Duo foldable layouts at October 21 showcase
KakaoTalk, Naver Band, Naver Webtoon, Naver Series, VLLO and games including Unluckily Lucky Game and Mabinogi Mobile presented Duo-optimized features, according to techm.kr.
An iPhone Duo app showcase held on October 21 introduced screen layouts and controls optimized for Apple's first foldable smartphone, with KakaoTalk, Naver Band, Naver Webtoon, Naver Series, VLLO, Unluckily Lucky Game and Mabinogi Mobile among the apps presenting Duo-specific features, according to techm.kr.
The device has a 13.6cm outer display when closed and a 19.3cm inner display when unfolded. Apple says the two screens share the same aspect ratio so screen content continues naturally when the device is opened, and the company provides developers with related APIs and detailed guidelines to encourage optimization for the iPhone Duo.
How the apps use the larger screen
KakaoTalk places the chat list and conversation window side by side when the device is unfolded. Naver Band shows a single feed when closed, then places the post list and body together when opened, and supports dragging images from the photo app into Band posts via Split View.
Naver Webtoon keeps the reading position when the device is opened or closed, moves viewer controls vertically to the side and lets users adjust content width between 50% and 100% of the screen. Naver Series shows two pages side by side when unfolded in landscape, switches to a single-page view in portrait and applies a page-turn curl effect when the device is half-folded.
VLLO places the preview on the left and the timeline on the right when unfolded, with a movable divider to adjust the ratio and frequent controls positioned to avoid the hinge. Unluckily Lucky Game shows the battlefield on the right and the mythic character combination table on the left, with boss alerts displayed inside the battlefield and boss timers continuing to show when the device is closed. Nexon's Mabinogi Mobile offers optimizations for raid combat visibility, supports landscape and portrait switching and adds compass-based one-touch auto battle.
Apple launched the iPhone Duo as its first foldable smartphone, and the October 21 event focused on how domestic Korean apps have adapted their interfaces for the device.
