DuoWall

DuoWall is a wallpaper and device mockup app from independent developer Faisal Alrajhi. It combines two jobs in one place: designing still-image wallpapers and placing your own images inside device frames for sharing. Wallpaper styles include gradients, solid colors, retro and dot-matrix looks, glass and glow effects, shapes, patterns, typography and, as of version 1.2, a Papercraft set with paper landscapes, cut-out arches, folded forms and torn paper. Colors can be picked from curated palettes or the system color picker, with options for texture and light and dark companions. The mockup side lets you place images in iPhone, iPad or Duo frames, arrange several devices, and export PNGs, including with a transparent background. Designs are saved in a local library with collections, and the developer states rendering and editing happen on the device, with no account, ads or subscription. The app is free. It is aimed at people who like to customize their home and lock screens, and at anyone who needs quick device mockups. The developer notes it is independent and not affiliated with Apple.

DuoWall's App Store description says its Duo Pair option creates coordinated wallpapers for the inner and outer displays, and lets you preview the composition in different device poses. The version 1.2 release notes (October 24, 2026) add a new editing toolbar on iPhone Duo that keeps common actions within reach, plus larger previews on wide screens. DuoDiscover has not yet tested it on an iPhone Duo.
