Very good app. I was able to snap a pic of my room (wall), apply some colors, realized that I couldn’t find a color that I liked on the wall. ( had I went to the store, picked a color, came home and painted, I would have been disappointed, this app saved me the time, money and frustration) Using this app I was able to decide on painting another portion of the room, found a color I liked. The paint codes were useless at Lowe’s, but this app gave me a color that I was able to save to my photo album, then using Sherman Williams app, I was able to import the color (pic) from Paint Tester and Sherwin Williams found a matching color. My results match Paint Tester to a T, I got exactly what I was able to produce using the app. I love this and would recommend it.
