Apple’s foldable, inner and outer displays, Split View and the physical poses — book, tent, laptop. Check how your site folds before anyone is holding one.

Real rendering, not a resized window

A genuine mobile viewport with the device’s pixel ratio, safe-area insets, touch events and iOS user agent — with Safari, Chrome or Vivaldi drawn around your page.

iPhone Duo, iPhone 18 and 17 Pro, the 16 and 15 range, Pixel — every display, every pose.
