Measure your place. Design what comes next. Spasio brings room scanning, editable floor plans, furniture layouts and interior ideas into one project on your iPhone. START WITH YOUR SPACE Capture walls, doors and windows with a LIDAR-equipped iPhone, then review and adjust the result. Without LIDAR, mark floor or ceiling corners and calibrate the estimated plan with real measurements. MAKE THE PLAN YOURS Edit walls and openings, add dimensions and notes, and arrange furniture from an expanded library. Adjust furniture sizes and materials. Inspect the 3D model, calculate areas and quantities, then export PDF, PNG, layered DXF or supported 3D formats. EXPLORE A NEW INTERIOR Take a photo directly or use a view of your 3D model. Choose a style, mark a wall or an item, and explore colors, furniture removal and new layouts. Generated images are design concepts, not measured drawings. TOOLS FOR THE WAY YOU WORK Choose Standard, Architect, Real Estate or Studio. Prepare a property listing draft, use room-volume and TV-sizing tools, or organize people, tasks and notes locally in Studio. YOUR FIRST TWO PROJECTS Create two real projects free with full project tools. A Pro subscription unlocks unlimited new projects. Deleting a project does not reset the free allowance. Previously earned project access is preserved. Monthly and yearly subscriptions are available; eligible accounts may receive a one-week introductory trial where offered. The exact price and renewal terms appear before purchase. AI services use a separate credit balance and are not unlimited with Pro. Each paid AI action shows its credit cost before you continue. Additional credits are available as in-app purchases. YOUR PROJECTS AND PRIVACY Saved scans stay on your device. Selected photos, instructions and relevant plan details are processed online only after your consent. Sharing a completed render with CCA for quality review is optional, can be withdrawn, and is retained privately for up to 30 days. You can render without this extra sharing permission. Made by CCA, creative computational architecture. Manage or cancel subscriptions in your App Store account settings.
