Not very good…..
I tried to use the app on a mens T-shirt, I measured the item 1st myself with a measuring tape, aside from the fact that the app basically wanted me to take pictures on the floor which I don’t know a lot of people who are doing that anymore but I guess there are still some, it was super inconvenient considering we take pictures on a board that is an angle at waste level so trying to hold my phone in the air to get the stupid dot into the center of the circle while I can’t even see the screen because I have to hold it so high above my head just to get the right angle which is a completely off angle of the shirt…. It was super inconvenient… and I noticed the first measurement specifically the pit to pit was 3 inches off. Then I tried to retake it and it was 5 inches less than it was the first time, so 8 inches inches off…. The third photo I tried to take of the same shirt came back as 5 inches bigger than it was… and the fourth photo was 2 inches smaller than the actual measurement. So, in conclusion, the app doesn’t work very well and it completely wasted my time.
