Can you synchronize a winner reveal across phones and a projector?

Yes, with a shared event state and a rehearsed release process. Exact simultaneity cannot be guaranteed across every network and device, but the system can coordinate the reveal and recover consistently when a screen reconnects.

What a solution might involve

Separate preparation, locked results, countdown, and reveal. Give authorized organizers control over transitions, and ensure public screens ask the server which phase is current. Test the projector layout separately from the participant phone view and rehearse a fallback announcement.

What needs care

A client-side timer is not an authoritative event clock. Devices may sleep, lose connectivity, or have different local times. Results should not be delivered to public browsers before release merely because a visual animation hides them.

How we would judge whether it works

A fresh or reconnected screen shows the correct phase. Results are unavailable before authorization and visible afterward. The organizer can rehearse the sequence, understands network-dependent timing limits, and has a nontechnical recovery plan.

Likely engagement

Business Engine: $5,000 to $15,000. This is a likely starting tier, not a quote. Scope, access, dependencies, and responsibility for operation need agreement first.

What to send first

Share the run of show, projector setup, desired sequence, and who is authorized to release the results.

Send me the messy version.
