Measure

Measure helps you with quick, everyday measurements around the house or office — similar to a tape measure. With the Measure app, you can:
– Measure the length and height of objects in the real world ​like​ the size of a rug, the width of a cabinet, or the height of a table
– Switch between imperial and metric units
– Save photos of your measurements for later

Move your phone around the space to find flat surfaces such as tabletops or the floor. Then drag a length tool or height tool into the scene, and adjust it to the right size. Tap the camera icon to snap a photo for later, or tap the trash icon to start a new measurement.  It does take a bit of time to get used to, but once you get the hang of it, it is really great!

Measurements taken with this app are estimates, but very good ones!
