The Problem

DWG files shouldn't require a desktop

Construction professionals need access to drawings on site — but existing solutions are clunky, require internet, or force you to convert files first.

No internet on site

Cloud-based viewers are useless in basements, remote sites, or areas with poor connectivity.

Forced file conversion

Converting DWG to PDF loses layers, dimensions, and metadata — exactly what you need on site.

Chained to a laptop

AutoCAD and desktop viewers aren't practical when you're walking a job site with dirty gloves.

The Solution

Your drawings. Your device. Zero dependencies.

PlanInspect reads DWG files natively on your iPad or iPhone using a custom-built Swift parser. No uploads, no third-party servers, no waiting.

100% on-device

Your drawings never leave your device. Works completely offline.

Instant rendering

Native Metal rendering for silky smooth pan, zoom, and interaction.

Full DWG fidelity

See every layer, block, and entity. No conversion artifacts.

Privacy first

No cloud accounts, no data collection, no analytics on your files.

Features

Everything you need on site

Professional tools built for the field — from quick measurements to detailed markups and exports.

Open DWG Natively

Import DWG files directly from Files, email, AirDrop, or any cloud storage. No conversion needed.

Precise Measurements

Tap-to-measure distances, areas, and angles directly on the drawing with real-world accuracy.

Site Notes

Pin sticky notes anywhere on the plan — log observations, defects, or tasks with photos directly at the exact location on the drawing.

PDF Report Export

Generate professional PDF reports with all your notes, photos, and observations. Share a complete inspection document in one tap.

Markup & Annotate

Add arrows, shapes, and highlights directly on the plan. Save and share annotated versions.

Toggle layers on/off, isolate specific elements, and navigate complex multi-layer drawings.

Smooth Navigation

Metal-powered rendering with fluid pinch-to-zoom, pan, and rotate — even on large drawings.

Export & Share

Export annotated drawings as PDF, images, or share directly with your team via AirDrop or email.

Fully Offline

Works entirely without internet. Perfect for underground sites, remote locations, or airplane mode.

iPhone & iPad

Optimized for both form factors. Quick look on iPhone, detailed work on iPad with Apple Pencil.

Secure & Private

Your files never leave your device. No cloud uploads, no accounts, no tracking.
