OctaLab

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.
