What’s inside

One app, five roles. Every feature is designed around the reality that 10 000 phones can’t all be online at once.

Works without signal

Map, timetable, FAQ, blog and POIs ship inside the app. When 10 000 phones saturate the same cell tower, your guide stays on-screen.

Emergency & support

Owner-broadcast alerts reach every device. Support threads to helpers. Emergency numbers ship with the app — no connection needed.

Encrypted at rest

GPS positions and session tokens are AES-256-GCM encrypted. European-hosted, GDPR / revDSG-compliant. Your data stays in Europe.

GPS friend-finder

Time-limited location sharing between friends. No permanent tracking — you set the window, it stops automatically.

Multi-language

UI and content in multiple languages. Switch in-app; content falls back gracefully when a translation is missing.

Roles for everyone

Attendees navigate and connect. Helpers coordinate. Service providers run their stall page. Organizers publish content live.
