FAQ
Can the application run on both Android mobile phones and Windows Desktop?
Yes! Built with Kotlin Multiplatform Compose, the exact same core codebase compiles into a native Android APK and a standalone Windows/Mac Desktop application with a responsive UI tailored for both screens.
Does the app support offline mode when there is no internet connection?
Yes! Local data is saved securely using Room KMP DB. When internet connectivity is restored, data automatically synchronizes with your centralized Node.js server via WebSockets.
How does the 2FA Google Authenticator setup work?
We generate a visual QR Code on screen that users scan using Google Authenticator, Authy, or FreeOTP apps to generate secure 6-digit TOTP verification codes.
Will I receive the full source code for the app and backend server?
Yes, production-ready, clean source code for the Android app, Windows Desktop app, Node.js backend server, and Web Admin Panel is included in all packages.
Do you provide assistance with server setup and app deployment?
Yes! I provide step-by-step assistance for deploying the Node.js backend server, configuring SQLite database tables, and setting up initial admin credentials.
