Two days ago I had to assemble a "Paint Schedule" pronto: "The painter is starting in 2 days. Help!" Paint is sold everywhere but not having my dependable Benjamin Moore "fan decks" of colors nearby, it was time to be resourceful, so... it was all Benjamin Moore "Color Capture App".
Color accuracy was MUCH better in my color memory (part of, I suppose, my design talent!) than on my laptop on the B. Moore website (a website I did NOT love anyway). The app allowed me to assemble the colors for the whole house and e-mail the names with teeny swatches as a "presentation". Along with my recommendations of paint finishes, proper ceiling colors and some carefully written notes--DONE!
My Florida clients use Sherwin Williams Paints and they have an app as well. Set up differently, it's also very user-(and Designer) friendly and I can't wait till they have more dealers in the Chicago area so that I can be a bit more diverse in my choices.
When I got my iPhone, I immediately downloaded and bought all sorts of Interior Design apps and, after this wonderful experience of completing a painting project so efficiently, I browsed Design apps again.
There are a couple of apps that help you lay out your space, including some colors and finishes in 2D or (I didn't download this one) 3D. Several apps show what is in style, some coordinated projects as inspiration (Dream Home) that are like design magazine/book apps. Pottery Barn, IKEA and others (even Steelcase for offices) have catalogs and sales updated (One Kings Lane). Also: eBay, Overstock.com have apps. There are MANY "green" apps including "Dwell" -the magazine-- which is Beautiful AND Informative. There is an app called "Interior Design" that is a dictionary of Design terms (and maybe more that I haven't figured out yet).
I won't comment on the apps that have Designer portfolios...I didn't have a time to research how those shown get included.... like HGTV's listings? They have an app too!
And, for me, ASID (American Society of Interior Designers) has an app!! They have trade sources and organization information.
