Flat Design / Vector Minimalism vs Metro

フラットデザイン / ベクターミニマリズム / メトロ

Flat Design / Vector Minimalism comes from UI Expression and Metro from Microsoft UI. Both are read here as style. They are reached for with some of the same intent, which is where they get confused.

Flat Design / Vector Minimalism

Reduces information to plain planes and color, portable across screens and media.

Metro

Windows Phone's flat language, which cast type rather than icons in the lead role. Large typography, flat-color live tiles and layouts that run off the edge of the screen transplanted the clarity of transit signage into UI, opening the flat era ahead of iOS 7.
