A little world by DevItUp
A playful little desktop for your iPhone. Open your miniature laptop, explore familiar little apps, and make it yours.
Coming to the App Store
For iPhone and iPhone Duo · Requires iOS 27 or later
01 / Small computer energy
A macOS-inspired desktop, reimagined as a miniature playground. Your wallpaper, a colourful dock, and useful little apps that feel right at home.

On a regular iPhone, tap the virtual lid to open LittleBook. Choose Close LittleBook from its menu to tuck it away. Your documents stay saved, ready for your next little moment.
Pick an app from the dock. Close its window to see your desktop, minimise it to return later, or go full screen for a closer look. One active window keeps things pleasantly simple.
Type on the virtual keyboard, move the pointer with one finger, and scroll with two. Direct touch works too. In LittleBrowser, scroll with the trackpad and touch webpage links and forms directly.
LittleBook is a desktop simulator within an iOS app. It does not run native macOS applications.
Made for iPhone Duo
Fold iPhone Duo into portrait tabletop posture and LittleBook falls into place: your desktop above the fold, your keyboard and trackpad below.
It’s the tiny-laptop moment. Unfold and rotate to landscape for a larger desktop with direct touch. Your regular iPhone gets its own portrait laptop experience, with a virtual opening lid.
Find your little setupWallpaper, menu bar, dock and your active app.
↓Virtual keys and a roomy trackpad, right where your hands expect them.
02 / A dock full of possibilities
Catch a thought, sketch a daydream, make a plan. All the core apps are included, with no Pro upgrade needed.
