iPhone Distance meter app

[zoran]

Are there any distance meter apps available for my iPhone to measure the distances between the walls of my house?

Apple provides the Measure app.

Anything else, maybe something more precise?

If your phone has AR sensor on the front, the Measure app is as close as you can get in terms of preciseness. It is after all built by the guys that built your phone.

I don't know if the iPhone 6S+ has such a sensor.
