I'm a skeptic when it comes to apps. Since there weren't many reviews for this app I was reluctant to spent $9.99. I emailed the developer to see if there was a trial version. He or she gave me options for the classic version which I was unaware of. Because of their detailed response I knew it wasn't a "canned" email. I am a residential painting contractor and know if this works-and it does, I'll make my money back 10 times over on the first use. I purchased the app, and checked my newly painted window trim. It immediately popped up the manufacturer, name, ID number of the color and the colorants. I was and am blown away. Later that day I used it to check some paint we just had matched the prior week. Incredibly, it showed a few minor color ticks away from what the paint should be. So, the app did it's job and told me why the color we matched (prior to the app) was REALLY close, but not perfect. Next time it will save me well over $100 and increase customer satisfaction. This app is a game changer. It's not tucked away in a folder on the third page of my iPhone. In one day it earned a spot without a folder on my first page. Designers, contractors, remodelers, DIYers and anyone else that needs to match paint. This will more than pay for itself on the first use. I couldn't be more impressed and haven't even made time to go through what looks like a thorough/intuitive guided tour. Delete the other paint apps; this one is the real deal.
