OctaLab is a visual app builder. Design, prototype, and preview app ideas for iPhone, iPad, and Apple Watch, directly on your device, no code required. Place SwiftUI components on a device canvas, wire up navigation between screens, define your data and actions, then run a live, interactive preview to feel how your app works. DESIGN VISUALLY • Drag and drop from a library of SwiftUI components onto a device canvas • Resize, position, and style each component with a property inspector • Add real photos from your library to image components • Build for iPhone, iPad, or Apple Watch, the canvas adapts to each CONNECT YOUR SCREENS • Lay out screens on a visual flowchart canvas • Connect them with navigation links: push, sheet, full screen, tab, and alert • Mark an entry screen and see the whole flow at a glance DATA AND LOGIC • Define data models with typed fields and custom enums • Two-way bindings between components and live context variables • Build reusable actions: change state, navigate, call APIs, and more • Import OpenAPI specs to model real API endpoints PREVIEW INSTANTLY • Run your prototype in a simulated device frame • Tap through real interactions: buttons, fields, toggles, sliders • Switch between iPhone, iPad, and Apple Watch as you go • Light and dark mode ORGANIZE YOUR WORK • Start blank or from a built-in template (Todo, Login, Dashboard, Chat, Social, Banking) • Rename, duplicate, and manage all your projects in one place • Projects are saved locally on your device OctaLab is built for designers, makers, students, and anyone who wants to shape an app idea quickly and see it run without writing a line of code.
