Dexa: UML Class Diagrams

Dexa is a UML class diagram editor for developers, students and software architects. Build diagrams visually on an interactive canvas, or write them in PlantUML or Mermaid, on iPhone, iPad, Mac and Apple Vision Pro. A VISUAL CANVAS Drag classes around a zoomable canvas and edit them in the inspector: properties, methods, parameters and visibility (+, -, #, ~). Classes, interfaces, abstract classes and enums, with generics. SIX RELATIONSHIP TYPES Inheritance, realization, association, aggregation, composition and dependency, drawn with the right UML arrows. PLANTUML AND MERMAID Open and save PlantUML (.puml, .plantuml) and Mermaid (.mmd, .mermaid) files; Dexa recognizes the format on its own. With Dexa Pro, edit the source code directly. PRESENT ON TV While Screen Mirroring to an Apple TV or another AirPlay display, or with a display connected, tap the TV button to show just the diagram, full screen, while you keep editing on your iPhone or iPad. The TV follows your zoom and pan. AUTO LAYOUT THAT REMEMBERS Auto Layout arranges your classes in clean hierarchical layers whenever you ask. The positions you choose are saved in the file, so a diagram opens exactly as you left it. EXPORT WITH DEXA PRO Export diagrams as high-resolution PNG or PDF. Dexa Pro is a one-time purchase, shared with your family, that unlocks export and the source code editor. Everything else is free. MADE FOR EVERY APPLE DEVICE • iPhone, in portrait and landscape. • iPad, in any orientation, with the inspector in a sidebar. • Mac, as a native document app. • Apple Vision Pro, in a window in your space. ICLOUD Your diagrams are documents in iCloud Drive, so they stay in sync across your devices and show up in Files and Finder. PRIVATE No account, no ads, no tracking. Dexa doesn't collect any data.
