Most digital signage costs $20–50/month per screen and still buffers. LightLoop is completely free, uses your Google Drive for storage, and caches everything locally on Apple TV so rooms never buffer — even if the internet drops mid-service. Built for churches: Planning Center Check-In triggers a full-screen Welcome Party the instant a child checks in. Pause Points let teachers hold a curriculum video mid-lesson and advance on cue. Every feature. Unlimited screens. $0.
