Built for the realities of education IT
Instant Emergency Alerts
One MQTT message overrides every display on campus with a full-screen emergency alert. Red background, large text, audio alarm. Reach every room in milliseconds, not minutes.
Tamper-Proof Kiosk Mode
Students cannot exit, change settings, or access the notification bar. KingKiosk's kiosk mode with Android device-owner makes displays completely locked down and uninterruptible.
Bell Schedule Integration
Display the current period, time remaining, and next class automatically. Different schedules for regular days, half days, and assemblies — all switchable via MQTT or on a timer.
PA System Integration
With the Feature Server, displays become announcement speakers. Text-to-speech with 100+ voices and 30+ languages. Broadcast to one room or every screen on campus simultaneously.
Use Existing Hardware
KingKiosk runs on the Android tablets, iPads, Windows PCs, and Raspberry Pis you already have. No need to buy proprietary signage hardware. 5-Pack license is just $8 per screen.
On-Premises Only
No student data leaves the school network. No cloud servers. No external dependencies. KingKiosk runs on local infrastructure with your MQTT broker. Meets FERPA and COPPA requirements for data locality.
Push content with a single command
Every display is an MQTT endpoint. IT staff can script deployments, schedule content, and trigger alerts programmatically.

How much does KingKiosk cost for schools?
KingKiosk starts at $20 per screen (one-time purchase) or $40 for a 5-pack ($8 per screen). For campus-wide deployments, enterprise licensing offers unlimited devices with volume discounts and fleet management tools. Contact sales for a quote.
Can students tamper with classroom displays?
No. KingKiosk's kiosk mode locks down the device completely — no notification bar, no app switching, no settings access. Combined with Android's device owner mode or managed deployment, the display becomes a dedicated, tamper-proof signage endpoint.
Can KingKiosk display emergency alerts across all screens?
Yes. Because KingKiosk is MQTT-controlled, you can publish a single message that instantly pushes an alert to every display on campus. Override the current layout with a full-screen emergency message, change the background color to red, and trigger audio alerts — all in one MQTT publish.
What hardware do I need?
KingKiosk runs on Android tablets, iPads, Windows PCs, macOS machines, Linux computers (including Raspberry Pi), and Apple TV. Most schools already have compatible hardware. An MQTT broker (like the free Mosquitto) is the only infrastructure requirement.
Does KingKiosk require a cloud connection?
No. KingKiosk operates entirely on your local network. This is critical for schools: student data stays on-premises, there are no external dependencies, and displays keep working even if the internet goes down.
