Just downloaded it.

So far so good --just downloaded it -it measured three rooms and it came in very accurately, even rooms with partial glass
walls. I give it a thumbs up

Really helpful for oddly-shaped spaces

I just use this app on one of my rooms which has a number of different walls as well as alcoves. It worked pretty well although it took several tries to get the space measurement to seem accurate. And different tries yielded different measurements. I hope there are more features added such as the ability to add windows and doors into the diagram and the ability to edit the diagram dimensions.

Great App

This is a great app and very accurate if you make sure to keep your phone at a good angle and move quickly. If you do not get a three star accuracy rating i would do it again. Took one or two times to get a good handle on it, but after that we found it to match up with our manual measurements.
