It seems like just yesterday that we were whipping out our Razr flip phones and calling friends for directions.

Nowadays, our phones not only provide satellite coordinates for the party but also order the car service to get us there and tell us where to pick up wine en route.

The trouble with navigating this brave new world of apps for everything? There are literally millions to choose from. (Needle, meet haystack.)

To spare you the detective work, we caught up with some of our favorite tastemakers (from big-deal CEOs to up-and-coming fashion designers) and asked them to share their current app obsessions.

Here you’ll find a social network designed to get you in shape, a super-simple platform for selling old clothes, and a pocket-sized sommelier that helps you pair your wine with your dinner (and properly pronounce Gewürztraminer while you’re at it.)

Scroll through our top recommendations, download the ones that strike your fancy--then get to sharing with your friends and followers.
