King Kiosk is the world's first Programmable Display Runtime — turn any iPad or iPhone into a multi-window display surface you can compose, control, and orchestrate in real time over MQTT. It's not digital signage. It's not a kiosk. It's not a dashboard. It's all of those — and none of them — because you decide what every screen becomes by sending it instructions. A REAL WINDOWING SYSTEM ON iOS Run a clock, a weather widget, a live camera feed, a Home Assistant panel, and a media player on the same screen, each in its own resizable, independently controllable tile. Floating mode for pixel-perfect layouts, or tiling mode for automatic, non-overlapping grids. 35+ BUILT-IN WIDGETS Clocks, weather, media player, YouTube, image carousels, gauges, charts, maps, calendars, PDF viewer, animated text, RSS feeds, MQTT-driven images and buttons, an Alarmo security panel, an LED light panel, DLNA player, an intercom, games, and a real-time canvas widget for declarative graphics. MQTT-NATIVE FROM THE GROUND UP Every widget, every layout, every system setting is addressable over MQTT. 100+ commands. Build automations in Home Assistant, Node-RED, or any tool that speaks MQTT. Save entire layouts as named "screen states" and recall them on schedule. DEEP HOME ASSISTANT INTEGRATION Auto-discovers itself to Home Assistant. Publishes sensor data (battery, network, location, presence). Responds to automations. Bidirectional calendar sync. Person and object detection feeds straight into HA. AI VOICE CONTROL Connect to Home Assistant conversation agents, Anthropic Claude, OpenAI, Google Gemini, or local Ollama. Your displays can listen, understand, and respond. INTERCOM & BROADCAST Two-way WebRTC audio between devices, room-to-room paging, and full-fleet broadcast — built on the same engine as professional installed-audio gear. PRIVACY-FIRST, LOCAL-FIRST Your data stays on your network. Crash reports are off by default and explicitly opt-in. No analytics. No tracking. No cloud lock-in. GUIDED ACCESS KIOSK MODE Lock the device to King Kiosk for wall-mounted iPads, lobby displays, intercom stations, or smart-home control panels. Optional command signing (HMAC) for enterprise deployments. BUILT FOR FLEETS Deploy one device or a thousand. Replicate layouts across an entire fleet with a single MQTT message. Schedule layout changes by time of day or day of week. --- A new category for every screen. Visit kingkiosk.kallinnovations.com to see what's possible. Patent pending.
