LiDAR Vision and Ranging vs DepthTag

This app utilizes the iPhone or iPad rear-facing LiDAR to generate a user-adjustable depth field (color gradient), along with a numerical distance value to the center of the field accurate up to 5 meters. Useful for measuring short distances without a tape measure and for navigating small spaces in the dark. NOTE: LiDAR hardware is only present on iPhone 12 Pro or later models, and iPad Pro 2020 or later models.

DepthTag turns your iPhone Pro into a precise measuring tool. Point the camera at anything, tap, and it reads the exact distance using the LiDAR scanner. No tape measure, no guessing. REQUIRES A LiDAR SCANNER DepthTag needs the LiDAR sensor found on iPhone 12 Pro, 13 Pro, 14 Pro, 15 Pro, 16 Pro, and later Pro and Pro Max models. It does not work on non-Pro iPhones. POINT, TAP, MEASURE - Tap anywhere in the camera view to tag the exact distance to that point - A live reticle shows the distance under the crosshair as you move - Tags stay pinned in space, so you can capture several at once FOUR MEASURE MODES - Ruler: the straight-line distance between two points - Height: measure vertical clearances and object heights - Area: outline a surface and read its area - Tape: trace a winding path and get its total length BUILT FOR REAL WORK - Metric or imperial units, switch anytime - Floor clearance readout for quick height checks - Save, label, and revisit every measurement - Export your measurements when the job is done ON DEVICE AND PRIVATE - All depth processing happens on your iPhone - Nothing is uploaded, no account, no tracking - Works offline, anywhere Whether you are checking if furniture will fit, sizing up a room, planning a shelf, or measuring on a job site, DepthTag gives you fast, LiDAR-accurate numbers without unrolling a tape measure.
