About this app

UML Diagram Maker is a dedicated software modeling application for drawing unified modeling language diagrams, flowcharts, and system architecture structures directly on mobile devices. Designed for software engineers, system architects, computer science students, and technical project managers, this application provides a complete visual editing canvas for software design and system analysis.

Whether you need a class diagram maker for object-oriented design or an activity diagram tool for business processes, UML Diagram Maker includes all standard modeling elements and connectors required for formal documentation.

Supported Diagram Types

1. Structure Diagrams
- Class Diagram: Define classes, attributes, operations, inheritance, associations, aggregation, and composition relationships.
- Object Diagram: Inspect instantiated objects and runtime state relationships within your system architecture.
- Component Diagram: Map physical software components, interfaces, and module dependencies.
- Deployment Diagram: Visualize hardware nodes, execution environments, and artifact deployments.

2. Behavior Diagrams
- Activity Diagram: Model workflows, decision paths, parallel branches, and control flows.
- Use Case Diagram: Document system boundaries, actors, use cases, and include/extend relationships.
- Communication Diagram: Trace message sequences between interacting objects.

3. Process & Specialist Diagrams
- BPMN (Business Process Model and Notation): Map end-to-end business workflows, gateways, tasks, and events.
- Petri Net: Analyze concurrent systems, transitions, places, and arc weights.
- Reachability Graph: Evaluate state transitions in Petri net models.
- Syntax Tree: Construct parse trees and formal language structures.
- Flowchart: Build process decision trees and algorithm logic diagrams.
- SFC (Sequential Function Chart): Design industrial control and automation sequences.

Key Features

Interactive Visual Canvas
The drag-and-drop editor allows precise placement of nodes, custom line routing, and label adjustments. Dedicated shape libraries make it easy to select the exact UML element needed for your model.

Multiple Export Formats
Export your completed models into industry-standard file formats for documentation and presentation:
- SVG for scalable vector graphics in web documentation.
- PNG for clear image previews and reports.
- PDF for formal technical documents and printing.
- JSON for saving diagram source data and re-importing project files.

Real-Time Collaboration
Connect with team members to work on software models simultaneously over WebSockets. Every update syncs across connected clients in real time for joint software design sessions.

Local Storage & Privacy
Work on your diagrams offline. Your files can be stored locally on your device without mandatory account creation or cloud dependencies.

Target Audience
- Software Developers: Map object-oriented system structures and design patterns.
- Systems Engineers: Document deployment environments and structural dependencies.
- Computer Science Students: Learn UML syntax and complete academic software design assignments.
- Product Managers & Analysts: Draft process flows and functional requirements.

Use UML Diagram Maker to structure your software architectures, document codebases, and streamline system modeling on your Android device.
