About this app

This is a professional-grade HTTP packet capture and network debugging tool for mobile developers and testers, providing comprehensive real-time network traffic monitoring, analysis, and debugging capabilities for Android apps.

### Core Capabilities
- **Real-time Packet Capture**: Supports real-time HTTP/HTTPS packet capture and fine-grained packet viewing (request headers/body, response headers/body).
- **Analysis by Application**: Filters and analyzes network traffic by application to quickly locate the source of problems.
- **HTTPS Decryption**: Provides SSL/TLS certificate management and import, and supports encrypted traffic decryption analysis.
- **Request Simulation (Mock): Configurable rules allow for HTTP mocking, facilitating both online and offline debugging.
- **Modify and Replay**: Supports editing requests and responses after interception, and replays to verify the effectiveness of repairs.

### Why Use VPNService
Apps use Android's VPNService to implement system-level network data channels, enabling the following capabilities:
- **Network Interception**: Intercepts network requests and responses from other apps on the device using VPN technology. - **Packet Analysis**: Analyze HTTP/HTTPS traffic in real time, extracting and displaying key fields and data.
- **Network Debugging**: Provides request path tracing, performance observation, and problem location tools to assist in development and debugging.
- **Packet Rewriting**: Modifies intercepted requests, injects rules, and resends them to verify remediation solutions.

### Compliance and Transparency Statement
- **User Perception**: Continuously displays the VPN service status in the notification bar to ensure users are fully informed.
- **Permission Transparency**: Clearly explain the reason and purpose of VPN permissions during the authorization and onboarding process.
- **Functional Necessity**: VPNService is a necessary technical means for system-level network interception and analysis.
- **Security Boundary**: Used only for network debugging and analysis in development and testing scenarios; no user privacy data is collected.
- **HTTPS Compliance**: HTTPS decryption is only performed after the user has actively installed a trusted certificate and explicitly authorized it. Certificate management is fully controllable and removable.

### Applicable Scenarios
- Development debugging, API verification, problem reproduction and location
- Online problem tracking, weak network and exception handling verification
- Third-party SDK/embedded WebView network behavior analysis
- Rapidly construct and verify mock scenarios

Ratings and reviews

I love this app! if you need to maintain your own Situational awareness to prevent unnecessary or unwanted cyber events, then this is your app!

Too many ads.. Can't even close them even after watching. Force close and reopen.. Keep repeating

Tried every step given in that doc. Still getting ssl handshake error. I installed certificate already.
