What this app is. What it isn’t. What you could build.

One-liner

ArcSite is a mobile-first CAD tool for creating and viewing floor plans, designed for contractors, architects, and real estate professionals who need quick, accurate measurements and visual documentation on-site.

Strengths

Intuitive touch-based interface for drawing and editing floor plans directly on mobile devices
Highly accurate measurement tools with real-time dimensioning and scale calibration
Supports importing PDFs and images as base layers for tracing existing layouts
Clean, minimal design focused on workflow efficiency in field environments
Strong integration with common file formats (PDF, JPG, PNG) and export options

Weaknesses

Limited collaboration features—no real-time sharing or team access
No cloud sync across devices; users report losing work after app crashes or device changes
Exported files lack advanced CAD metadata or layer control
Some users complain about inconsistent scaling when importing non-standard PDFs: 'I imported a plan, but the dimensions were off by 20%.'
Lacks support for 3D views or elevation drawings

Opportunities

Build a lightweight cloud sync feature with version history to address data loss concerns
Add team collaboration via shared project links with comment/annotation tools
Introduce a free tier with basic features to capture early adopters and build trust
Develop a companion web dashboard for managing and organizing projects across devices
Add AI-assisted room labeling and automatic wall detection from scanned plans
