Tack-Tek makes it easy to create an accurate 3D model of your horse’s back, helping you better understand and precisely measure their unique saddle support area. Using your device’s native LiDAR technology* and Tack-Tek’s proprietary algorithms, the app captures a detailed 3D scan of your horse’s back and generates key measurements used by professional saddle fitters—so horse owners, riders, and saddle fitters make confident, data-driven saddle decisions. Create a personalized user profile and add horses to your account. Each horse has its own dedicated profile page, allowing you to track important details and maintain a clear history of scans and measurements over time. When you’re ready to scan, simply select a horse and follow the guided in-app tutorial. The scanning process is intuitive and easy to perform: hold your phone horizontally over your horse’s back, press the scan button, and slowly raise your device. Using your phone’s native LiDAR technology, Tack-Tek automatically captures the scan and securely sends it for processing.
