Features

Everything You Need on Mobile

Real-time Chat

Instant messaging powered by SignalR. Channels for teams, direct messages for private conversations. Messages sync across all your devices — phone, desktop, and web.

Push Notifications

Never miss a message. Firebase Cloud Messaging (Google Play build) or UnifiedPush (F-Droid build) delivers instant notifications even when the app is closed.

Photo Auto-Upload

Automatically backs up new photos and videos from your camera roll to your DotNetCloud server. Your memories stay on your hardware — not in someone else's cloud.

File Browser

Browse, download, and share files from your DotNetCloud server. Upload files and photos from your phone. Share links with external contacts.

Calendar

View and manage your calendar events on the go. Create, edit, and respond to event invitations. Syncs seamlessly with the server and your desktop clients.

Notes

Access and edit your Markdown notes from anywhere. Full note browsing with folders, tags, and search — all synced across your devices.

Music

Stream your music library directly from your DotNetCloud server. Browse by artist, album, or playlist — your entire collection in your pocket.

Offline Support

Chat messages are cached locally in SQLite. Read your message history even without an internet connection. Messages queue and send automatically when reconnected.

Secure Authentication

OAuth2/OIDC with PKCE — industry-standard secure login via the system browser. Tokens stored in Android Keystore for hardware-backed security. Supports MFA.

And More

Access your calendar, notes, contacts, and music — all from the same app. More modules are being added to the Android client with every release.

App Feature Screenshots Collage of 4-6 phone screenshots side by side showing different app views: (1) Chat conversation with messages, (2) Channel list / direct messages list, (3) File browser with folders and files, (4) Calendar month view, (5) Notes list with folders, (6) Music player. Use phone frame mockups arranged horizontally for a professional app showcase.

Capture: Take screenshots of these screens in the app and assemble into a landscape collage with device frames. Alternatively, use AI to generate representative mockups matching the actual UI.

Security

OAuth2/OIDC with PKCE — Authentication uses the Proof Key for Code Exchange flow, protecting against authorization code interception attacks.
Android Keystore — Access and refresh tokens are stored in the Android Keystore, backed by hardware security modules on supported devices.
System Browser Auth — Login happens in the system browser, not an embedded webview, preventing credential theft and supporting password managers.
TLS Everywhere — All communication between the app and your server uses HTTPS. Certificate pinning available for additional security.
Multi-Factor Authentication — Full support for TOTP (authenticator apps) and FIDO2 (hardware keys) when configured on the server.
