nextdooh is a cloud platform for managing digital signage screens — TVs, kiosks, menu boards, lobby displays. Upload media or web pages, build layouts, schedule when each one plays, and every paired screen catches up automatically.

Which displays work with nextdooh?

Any Android TV running 5.0 or later via the kiosk app. Tizen and webOS via the wrapped player. And any browser tab, as a fallback. Same dashboard, same controls.

How do I get started?

Drop a line to info@kryil.com with how many screens you're running and where. We'll come back with a tailored plan and onboarding within 24 hours.

How fast does content reach the screens?

Live via WebSocket — the manifest is pushed the moment you hit save, not on a five-minute polling interval. Online devices typically pick it up in a few seconds; flaky-line devices catch up the moment they reconnect.

Can I schedule different content at different times?

Yes — dayparting, day-of-week, and date overrides. A common pattern is breakfast 7–11, lunch 11–3, dinner after — all automatic.

What about emergency alerts?

Push a full-screen alert to every screen at once, or a rolling ticker overlay that doesn't interrupt the main content. Set colours, font size, expiry. Live via WebSocket to every connected device.

Do you log what played where?

Yes — proof-of-play logs for every screen, exportable as CSV. Hand them to advertisers, auditors, or yourself.

How is pricing structured?

Quoted on request, no public tiers. Email info@kryil.com with your screen count, locations, and content patterns — we'll respond within one business day with a plan, no sales call required.
