Digitize Reality: Transform your mobile device into a powerful 3D scanner. Simply point and record to create professional-grade 3D models. Pair with a compatible RTK device for centimeter-level accuracy, precise measurements, and geolocated 3D reconstructions. Visualize the captured model in the app, upload and export, and view it in AR. New ArcGIS Workflow: PIX4Dcatch now streams ArcGIS data in realtime in AR to provide in-field operators full contextual information about the entire site including 3D reconstructions and attributes. Our capture feature generates complete and defensible georeferenced 3D reconstructions which can be communicated seamlessly back to ArcGIS. New Guide-To Feature: PIX4Dcatch has a guide-to feature directing users to specified geolocated assets for staking, boosting onsite efficiency and accuracy. Just select the point or reconstruction you would like to find and follow the arrows in AR. WORKFLOW 1 – Scan & Capture Walk around your site. The app automatically gathers data and provides live feedback using iOS LiDAR, ensuring you capture every detail. For enhanced accuracy, use an RTK device compatible with PIX4Dcatch, PIX4D Autotags with a fully automated workflow, or combine both. 2 – Process, Analyze & Share Process your data by uploading to PIX4Dcloud for online analysis and sharing, or export to PIX4Dmatic for desktop processing. Both platforms offer a 14-day free trial. Projects can also be exported to third-party photogrammetry software. Measure spaces, document results, and enjoy all the benefits of a detailed 2D/3D model of your surroundings. 3 – View in AR Experience an immersive augmented-reality view. Display 3D models and points directly in your phone camera in AR. ____________________ USE CASES • Digitize construction sites • Measure stockpiles and other objects • Document underground utilities • Digitize indoor and outdoor spaces with Autotags • Visualize and verify 3D models in AR in real time • Perform single-point measurements with RTK accuracy ____________________ COMPATIBILITY • Optimized for LiDAR-equipped devices (Pro series phones) • All ARKit-enabled devices • RTK devices: Emlid Reach RX and RX2, TopCon HiPer CR, Bad Elf Flex Mini, Bad Elf Flex, Trimble DA2, Leica Zeno FLX100 ____________________ TERMS OF USE https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
DepthTag

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.

Verdict
The clearest difference is price: PIX4Dcatch at Free against DepthTag's $1.99. PIX4Dcatch also leads on update cadence (every 2 weeks vs every 2 months). DepthTag's advantage is in-app purchases (none vs 1) and iOS requirement (16.0 vs 18.0). On ads and device support there is nothing between them.
