Efibb PWA 2.0
One resilient app for learning, opportunity, and private productivity.
Install Efibb on supported phones and computers. Keep the public learning shell and selected pages available offline while authentication, payments, administrator controls, and private family data stay network-only.
Save useful public pages
Save this App Center or another safe public page. Private dashboards and sensitive routes are never offered for offline caching.
Share files into Utility Studio
On compatible installed devices, use the operating-system share sheet and choose Efibb to open a supported file locally.
Open converterControlled app refresh
Efibb detects a waiting service worker and lets you refresh into the new release without silently keeping stale assets.
Saved offline pages
No saved-page inventory loaded yet.
Security boundary: login, registration, password recovery, MFA, checkout, payments, administrator pages, messages, private family pages, and authenticated workspaces remain network-only.
