Instagram is most popular photo-sharing app out there with 30% of Millennials using it daily, according to Ypulse’s March monthly survey. Now the platform has released Layout, a stand-alone companion app that allows users to easily create photo collages, and includes fun ways to edit images. Existing photo editing apps, which many use before posting images on Instagram, often have clunky interfaces and are jammed with ads. Layout preserves Instagram’s simplicity while providing a tool already in demand, and is already being used by major brands like Victoria’s Secret, Sephora, and even Michelle Obama.
