About this app

AI agents write code fast they also ship architectural spaghetti. Architectum is a premium, offline-first system design tool for software architects and lead developers who enforce Vertical Slice Architecture (VSA) and domain boundaries before anyone writes business logic.

Stop drawing dead UML. Draw your system: group features into bounded contexts, place vertical slices, toggle UI / Logic / Data per slice, and connect dependencies to define cross-slice integration seams. Watch a production-style repository layout update in real time for C# (.NET 9), Go, or Dart (Flutter). Export a .zip and open it in your IDE your diagrams stay on your device; no mandatory cloud sync.

WHAT IT DOES
• System boundaries: bounded contexts and slices on a tablet-first canvas.
• Dependency mapping: visual links that inform scaffolding and integration stubs.
• Boilerplate: folder trees and stubs from your layout not your domain rules.
• Projects dashboard: multiple independent blueprints.
• Reference library: pattern glossary (CQRS, Mediator, VSA) educational, not part of code generation.

WHAT IT IS NOT
• Not an AI that writes your business logic.
• Not a generic whiteboard or full IDE design here, implement in VS Code or Android Studio.

Architectum requires a supported iPad; integrity checks apply for full export features per product configuration.

What’s new

- Improved startup stability to prevent rare loading issues on review/test environments.
- Refined security initialization behavior to reduce false-positive launch interruptions while keeping core integrity protections active.
- Updated store-facing metadata and screenshot messaging for clearer iPad-focused presentation.
- Minor quality and consistency improvements across onboarding/store content.
