Transform your iPhone into a professional 3D scanner with LiDAR Point Cloud. Capture rooms, objects, and spaces in stunning detail, then measure, film, clean up and export high-quality point clouds for professional use. PROFESSIONAL SCANNING Use your iPhone LiDAR sensor to create detailed 3D point clouds with up to 3 million points and 6mm precision. Perfect for architecture, construction, interior design, and 3D modeling. MEASURE IN 3D Tap any two points in a scan to get the real distance between them. Chain taps to measure a path, close the loop to measure an enclosed area, or let the app work out the room for you — floor area, floor-to-ceiling height and volume, calculated from the scan itself. CINEMATIC VIDEO Turn any scan into a flythrough video worth sharing. Choose a camera move, pick widescreen, square or vertical, and watch the point cloud draw itself in exactly as you scanned it. Export up to 4K at 60 frames per second. CLEAN-UP STUDIO Crop away the room next door or the ceiling, strip out the haze of stray points every LiDAR sensor leaves behind, and stand a crooked scan upright with the floor levelled and squared to the axes. Everything previews live on the cloud, and clean-up always saves a new scan — your original capture is never changed. POWERFUL FEATURES Scan environments in real-time with instant visual feedback View your scans with smooth Metal-accelerated 3D rendering Measure distances, paths, areas and whole rooms Export PLY files for use in professional 3D software Record flythrough videos for clients and social media Organise your scans in a personal library Choose from multiple depth visualization palettes Customize point size and rendering quality EASY TO USE Simply point your iPhone at any space and watch as a detailed point cloud builds in real-time. The intuitive interface makes professional 3D scanning accessible to everyone. PRO FEATURES Upgrade to Pro for unlimited measurements with areas and room dimensions, watermark-free 4K 60fps flythrough videos, noise removal and straightening in the Clean-Up Studio, PLY export, Ultra quality scanning with 3 million points, premium depth palettes including Thermal, Rainbow and Ocean, and unlimited scan storage. FREE TO START Get started with full scanning capabilities. Capture and save up to 5 scans completely free, measure one distance in every scan, crop your scans, and share a 5-second flythrough video.
