Über NetInfo

NetInfo is a robust, privacy-focused mobile application designed to provide detailed insights into your device's network connectivity. It monitors and displays real-time network information, including connection status, IP addresses, and network capabilities, and integrates with external services to fetch public IP details and NTP (Network Time Protocol) data. Users can save network information as HTML files for later reference, with a clean, ad-free interface that prioritizes user privacy by avoiding tracking. Perfect for network enthusiasts, IT professionals, or anyone curious about their device's network status, NetInfo offers a comprehensive and user-friendly experience, completely free of charge.

## Key Features - **Real-Time Network Monitoring**: Displays detailed network information, including signal strength, bandwidth, transport types (WiFi, cellular, Ethernet, etc.), and link properties like DNS servers and IP addresses. - **Public IP Information**: Retrieves and displays public IPv4 and IPv6 addresses, with clickable links to view detailed IP information via external services. - **NTP Data Integration**: Fetches time synchronization data from NTP servers (e.g., pool.ntp.org), including stratum, offset, and delay metrics. - **File Saving**: Saves network information as HTML files in the device's Downloads directory for easy access and sharing. - **WebView Interface**: Presents network data in a formatted, scrollable WebView, with support for clicking IP addresses to view additional details in a browser. - **Privacy-Focused**: No ads or user tracking, ensuring a secure and uninterrupted experience. - **Free to Use**: All features are available at no cost, with no in-app purchases or hidden fees. - **Error Handling**: Provides clear error messages for network issues, such as loss of connectivity or invalid NTP responses.

## Application Screens - **Main Screen**: Displays real-time network information in a WebView, including: - Network capabilities (e.g., signal strength, bandwidth, transport types). - Link properties (e.g., interface name, DNS servers, DHCP details). - Public IP addresses and associated metadata (when requested). - NTP data, including server details and time offset (when requested). - **Controls**: Features buttons to: - **Save**: Stores the displayed network information as an HTML file in the Downloads directory. - **Extra Data**: Fetches and displays public IP details and NTP data from external services. - **Exit**: Closes the application cleanly, unregistering network callbacks.

## Supported Functionality - **Network Types**: Monitors WiFi, cellular, Ethernet, Bluetooth, VPN, satellite, and more, with detailed capability flags (e.g., internet access, metered status). - **File Format**: Saves data in HTML format, styled for readability with a dark background and clickable IP links. - **External Integration**: Links to `iplocation.io` for IP details and queries `pool.ntp.org` for NTP data, ensuring accurate and up-to-date information.

## Notices - **Permissions Required**: - `INTERNET`: Necessary to fetch public IP addresses and NTP data from external servers. - `ACCESS_NETWORK_STATE`: Required to monitor network connectivity and capabilities. - `WRITE_EXTERNAL_STORAGE` (or MediaStore access): Needed to save HTML files to the Downloads directory.

- **Network Dependency**: Some features (e.g., public IP and NTP data) require an active internet connection. The app will display appropriate error messages if connectivity is lost. - **Storage**: Saved HTML files are stored in the `Downloads` directory, accessible via the device’s file manager.
