SimpleMSK helps individuals and professionals capture 3D surface models and organize models, projects and supporting records. Create an account directly without an organization invitation or prior approval. CAPTURE AND ORGANIZE • Guided 3D scanning with the front TrueDepth camera on a compatible iPhone, or with the rear LiDAR sensor on supported iPhone Pro and iPad Pro models. • Create projects, view and organize models and plans, and keep photo, video and document attachments together. • Manage records you are authorized to use and associate them with relevant projects. IPAD AND IPHONE • The app runs natively on both iPhone and iPad, with an adaptive workspace layout. • Devices without a front TrueDepth camera or a rear LiDAR sensor can still use account, project, model and attachment workflows. The scan entry is shown as unavailable with an explanation rather than failing silently. REQUIREMENTS AND AVAILABILITY 3D scanning requires compatible hardware, iOS 17 or later, and camera permission. The current iOS release provides free basic features. Usage limits apply, and guest access differs from registered account access. The app interface supports English, Simplified Chinese, Traditional Chinese, Spanish, French, Portuguese and Russian. Scan quality depends on the device, environment and operating technique. Models, measurements and plans used for medical, rehabilitation or orthotic work require review by a suitably qualified professional and do not replace professional medical judgment.
