Measure
An app that turns your iPhone camera into a free tape measure.
What Measure does
Measure is Apple's own measuring app for iPhone and iPad. You point the camera at something, tap two points, and it shows the distance. It can spot rectangles like picture frames on its own, and on Pro models with a LiDAR sensor it adds guide lines, height measurement for people and saved measurements.
If you searched for a measure app for iPhone, this is the one to try first. It's free, made by Apple, and needs no account or setup. Point your camera, add a start point, move to the end, and you get a length you can share as a screenshot.
It works best for quick checks: will this couch fit through the door, how wide is that window, how big is that box. It finds rectangular things like frames and doors automatically and gives you both sides. On iPhone and iPad Pro models with LiDAR, measuring gets steadier, and you get guide lines, a person's height and a history of your measurements.
Treat the results as estimates, not a replacement for a real tape. Its App Store rating is low compared with other measuring apps, and it doesn't draw floor plans or export anything beyond a screenshot. If you need room plans or more tools, the other apps in this category go further.
