About

K12Cast

Features
Read full description

K12Cast turns an iPhone, iPad, Apple TV, or Mac into a secure, centrally managed school display. Pair a screen in seconds, then publish announcements, images, videos, presentations, live streams, scheduled playlists, layouts, and urgent alerts from the K12Cast administration platform. Built for K–12 teams, K12Cast keeps playback synchronized, reports display health, responds to remote operations commands, and automatically recovers from temporary connectivity interruptions. Emergency communications can take over the full screen and confirm delivery back to authorized staff. An active K12Cast organization account is required. Pairing and content are managed by an authorized school, district, or organization administrator.
