Would probably be okay if it wasn't designed to frustrate you into signing up for a "free" trial that cost way too much if you forget to cancel. Unable to view measurements after the fact unless you pay money or sign up for the "free" trial. In addition, it is suspicious that it used almost 10 MB of data in 10 miniutes for what should be a self contained (45MB) app. Likely the data was to deliver ads but still not acceptable.

Nice idea, doesn't actually work. God, I wish it did. but i went to one of the smallest, most simple rooms in my house and the app made a total mismash out if it. Was also very difficult to connect lines to create actual geometry property. I get the feeling the tracker would work okay if my phone could float by itself, rotating in a single point in space, but because its more or less impossible to simulate that using human hands, it doesn't really understand what it's looking at. Sigh.

I wanted to give the facilities dept at my work the measurements of a high ceiling where the lightbulbs were out so they could bring the correct ladder size for the job. This worked perfectly, I couldn't imagine trying to wrangle a measuring tape on an 11ft tall ceiling. The constant reminder to sign up for premium was annoying, but for a quick measurement here and there it was great. I'll probably delete just because I don't need it that often, but functionally it's great.
