Understand the shape of the ground; not just how it looks. TerrainAttain uses the LiDAR sensor in compatible iPhone models to scan surfaces and transform depth data into an easy-to-read visual terrain map. Reveal contours, slope direction, high and low areas, and subtle elevation changes that can be difficult to judge by eye. Built for golfers and anyone who needs a clearer view of a surface, TerrainAttain helps you study putting greens, yards, floors, landscaping areas, and other terrain directly from your iPhone. HOW IT WORKS Point your iPhone at the surface. Move steadily to capture the area. Review the generated terrain visualization. Use the contour and elevation display to understand how the surface rises, falls, and breaks. FEATURES • LiDAR-powered surface scanning • Visual contour and elevation mapping • Clear slope and ground-shape visualization • Top-down views designed for quick interpretation • Useful for reading putting greens and inspecting terrain • Clean, focused interface designed for use on location SEE WHAT YOUR EYES MISS Small changes in elevation can have a major effect on how a golf ball rolls, how water moves across the ground, or how level a surface appears. TerrainAttain makes those changes easier to see and understand. Whether you are analyzing the break of a putting green, exploring the shape of your yard, or inspecting an indoor surface, TerrainAttain gives you a new perspective on the ground beneath you. DEVICE REQUIREMENTS TerrainAttain requires a compatible iPhone equipped with a LiDAR sensor. TerrainAttain is intended as a visualization and general informational tool. It is not a replacement for professional surveying, engineering, construction, or safety-certified measurement equipment. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Terrain Attain's advantage is update cadence (every 5 days vs every 3 months). On price and ads there is nothing between them.
