Qlone vs Structure

Qlone is a 3D scanner app for creating, editing and exporting models from real objects, available on iOS and macOS. Scanning can use a printable Qlone mat or mat-free AR and Photo modes; Photo mode supports 4K images. Editing tools can fill mesh holes, blur texture imperfections, simplify meshes, smooth or erase sections, and sculpt models. Export formats include OBJ, STL, FBX, GLB, PLY and X3D, with USDZ listed for iOS. The app also supports direct uploads to Sketchfab, i.materialise, Shapeways, Snapchat Lens Studio and CGTrader. Models can be shared as MP4 or GIF videos through iMessage, WhatsApp and other social platforms. The maker says mat-free scans are processed through Qlone Cloud and that it does not store or view users’ models; scans made with the mat are processed on the phone in real time. LiDAR is not required. The app is free to download, but premium export, animated AR view and 4K scanning require an upgrade. Premium Features costs 19.99 USD one-time and includes 50 cloud credits for mat-free scans.

Structure builds 3D scanning hardware and software for medical, clinical, and industrial applications. Its technology supports orthotic and prosthetic fitting, wound measurement, surgical planning, and patient monitoring. The Structure Sensor 3 attaches to compatible iPads and provides millimeter depth accuracy for body measurements. Developers can use the Structure SDK for raw depth frames, mesh extraction, foot measurement, and offline licensing; the SDK also supports apps in healthcare, industrial inspection, retail fit-tech, and augmented reality. Structure Capture exports STL, OBJ, and PLY CAD files directly from compatible iPhones and iPads, and includes a Scan Quality Indicator. The SDK detects foot landmarks such as metatarsals, heel point, and arch height. Capture works with specified TrueDepth-enabled iPhones and iPads running iOS 16 or iPadOS 16 or later, and Structure Sensor ST01, ST02, and ST03. A seven-day SDK trial costs nothing. Capture costs $19.99 a month or $199 a year; the Structure Sensor 3 costs $995, paid once. Commercial SDK distribution requires a contract and a quote.
