Curious World gives young kids a safe mobile library of games, videos, and ebooks

Parents are often worried about finding appropriate mobile content for young kids, but a new subscription service might have them covered.

Curious World, from veteran educational publisher Houghton Mifflin Harcourt, provides kids ages 3 to 7 with an ever-growing managed library of videos, games, and ebooks in a single mobile app. Launched today on iOS, the app covers eight areas of learning — including science, math, language and literacy, and creative expression — with a selection of content that expands weekly.
