1. I made sure I had good lighting, and I tried to measure a light colored box on a dark background, which should've been pretty simple.
2. 3.) Not good in low-light situations, so a black desk on brown carpet might not work, same with a brown desk on brown carpet.
3. 2.) Good with measurements where the object is facing flat to the screen, but not where there is any depth to the object (the app has no compensation for perspective).
4. I just went in to the garage for my tape measure instead :/Prior to recent versions of app, it worked well (albeit not really accurate, but it would give you a good idea).
5. The line hints don't work as expected, the placed lines move as you move the camera, it does not determine depth in terms of the object.
6. Needs lots of work.Changed my rating to 4 stars, now that you can drag and drop to adjust the points after the initial measure.
7. Has potential but needs work and maybe a tutorial.Installed on a Samsung Galaxy S9+, was very difficult to use, played around with the lighting quite a bit and was barely able to get it to semi work.
8. If you have nothing else, this might work for measurements accurate within 1/2" or so.
9. Giving ⭐⭐⭐ because although it isn't currently working, I recognize that this is a really big challenge and the UI looks good so farIt was actually fairly accurate compared to my assumption.
10. The interface is different; you used to measure by dropping and dragging measurements and it was great.
11. Tried natural light, tried in home LED, as much time as it took to finally recognize a surface you could have measured something multiple times using a traditional method.
