Key Features

We built the full journey from fan experience to operations, check-in, sponsors, and SaaS administration across 88 screens.

event

From event discovery to day-of guidance

The home screen presents recommended and upcoming events so fans can move from the list to details without getting lost. Event details bring together the date and time, venue, notices, venue guidance, and timetable links.

qr_code_scanner

QR check-in and digital membership card

Fans can scan a venue QR code and show a digital membership card to staff. Check-in records accumulate as visit history and stamps in the fan passport, making continued participation visible.

favorite

Favorite creators, stamps, and missions

Fans can view creator profiles and related events, then save favorites. Missions tied to visits, QR scans, and survey responses lead to rewards, keeping fans connected after the event.

dashboard

Operations dashboard

The dashboard shows member counts, visitors, same-day check-ins, and recent operations by tenant, brand, and event. It also supports period comparisons and CSV export.

calendar_month

Event timetable planning

Operators register each creator's appearance time, venue, and stage to build the event timetable. The schedule flows to the fan view and can also drive pre-event notices and time-change updates.

groups

Fan CRM

Teams review registration details, membership status, favorite creators, and consent status by tenant. CSV import and export plus duplicate-candidate review bring fan data scattered across services into one ledger.

analytics

Fan and event analytics

Analyze metrics for members, visits, retention, favorite creators, notifications, and sponsor initiatives by tenant, brand, and event. Period comparisons and CSV export are supported, and aggregation is limited to non-identifying data.

how_to_reg

Venue check-in and offline sync

Check-in terminals support both QR scanning and manual search by reception code. To keep reception running at venues with unstable connectivity, unsent data stays in a device queue and syncs in batches when the connection returns.

campaign

Sponsor campaign performance

The system aggregates participation, completions, and coupon use, giving sponsors a view of campaign results. Shared data is primarily anonymous aggregate data, and identifying information is limited to the consented scope.

admin_panel_settings

Multi-tenant SaaS administration

Monitor contracted tenants, retention, API error rates, and failed notifications or webhooks across the platform. Tenant creation and suspension, plans, usage limits, and external integrations are managed in one console.
