Your iPhone as a pocket digital measuring tape, always at hand. Point the camera, get length, height, area, and a full 3D room plan in seconds. No tape. No assistant. No guesswork.
One app replaces your tape measure, room planner, laser, and interior designer
Designed for contractors who bill by the millimetre, designers who plan in 3D, and homeowners who just want to know if the sofa will fit. Every measurement scenario your iPhone can solve, built around ARKit and LiDAR.
Point your iPhone camera at any object. Tap the start and end points to capture a precise dimension in centimetres, metres, inches, or feet. The AR session adapts to lighting, surface texture, and distance, so a 4 cm screw and a 4 m wall both stay accurate. Built on ARKit world tracking with frame-by-frame outlier filtering.
Walk through any room. The app builds a full 3D floor plan as you go, walls, windows, doors, furniture categorised automatically. Export to PDF or share as a 3D model with your contractor, architect, or insurance adjuster. Works on every iPhone Pro and iPad Pro with LiDAR sensor (12 Pro and newer).
No LiDAR? No problem. Walk along each wall, tap corners, and the app builds a clean orthogonal floor plan with self-intersection detection, angle snapping, and live mini-map preview. Works on every iPhone from iPhone Xs and up.
Measure angles between any two surfaces. Check if a wall is plumb, a shelf is square, a frame is level. Perfect for hanging artwork, aligning cabinets, or verifying corners during renovation, accurate to within a degree.
A reliable digital level powered by your iPhone's accelerometer. Vertical, horizontal, and free-rotation modes. Align shelves, picture frames, washing machines, or check that a floor isn't slanting, without digging through a toolbox.
Save measurements into project folders. Attach notes and photos. Export full PDF reports with dimensions and 2D floor plans, or share individual measurements via Messages, Mail, or AirDrop. Every measurement is one tap away from being delivered to your team.
Specific scenarios, specific tools. The app ships presets and accuracy profiles for the people who measure for a living, and for everyone who just needs to settle a dinner-table argument about whether the bookshelf fits.
Site surveys, punch lists, change orders. Export a PDF with measurements and floor plan before you leave the job.
Capture a room in 60 seconds. Plan layouts in 3D. Share the floor plan with clients before the first revision.
Measure for paint, tile, flooring, and wallpaper. The material calculator turns dimensions into shopping lists.
Generate floor plans for listings on the walkthrough. Buyers see a measured plan, not a guess.
Will the couch fit? Measure your space, save the dimensions, and check at IKEA, Home Depot, or wherever you shop.
A package, a parking spot, a kid's height. When the tape measure is in the garage, your iPhone is in your pocket.
There are three ways to measure a room. Two of them require a second pair of hands, a 25-foot tape, and good light. Here's the honest comparison.

Last updated for app version 5.0. iPhone Measure refers to Apple's built-in Measure app shipped with iOS.
Launch the app. Raise your iPhone toward the wall, floor, or object you want to measure. The AR session calibrates in under two seconds.
Tap the start point. Move your iPhone to the end point. Tap again. The measurement appears on screen in real time, in cm, m, inches, or feet.
Every measurement lands in your history with a thumbnail. Send a PDF to your client, share a screenshot in Messages, or save the full project for later.
