Chris Benz: I do love the eBay app on my iPad, it's so easy to use and navigate! I feel like eBay is a great design resource for all sorts of disciplines not just fashion. Art, interiors, everything!
Rachel Roy: Shazam -- to solve all music questions; Stars -- I am obsessed with constellations and what is beyond this realm; Stress Free With Deepak Chopra -- adore this man, never enough healing to go around; Style.com -- perfect for work; crossword puzzles.
Jan Arnold: My No. 1 favorite iPad style app is Style.com. During Fashion Week, I can only be at so many shows, but with Style.com at my fingertips, I can stay up-to-date with all of my favorite designers.
