Features
Packet Capture & Packet Sniffer
Capture HTTP/HTTPS/WebSocket traffic using local VPN technology and view full request and response details in real time, including status codes, headers, and body data. Choose from multiple view modes, such as raw data, JSON, XML, HTML, images, or videos, for seamless debugging. Packet Capture Pro works as a powerful packet sniffer and analysis tool on your device.
Quick Filtering
Quickly pinpoint issues with keyword search and URL filtering, then narrow results by content type (such as JSON, HTML, XML, images, or videos). Create bookmarks to organize and instantly filter your data, and customize color rules to highlight different types of content.
Rewrite & Replay
Rewrite is one of PCP’s core debugging features. It allows automatic modification of network responses based on preset rules. Five modes are supported: request replacement, response replacement, request modification, response modification, and redirection. Multiple rewrite rules can run simultaneously, making it easy to simulate and debug complex network behaviors efficiently.
Replay enables you to re-execute captured requests to reproduce issues. Advanced Replay allows you to customize replay counts, delays, and intervals, making stress testing and validation more efficient.
Cross-Device Collaboration
Stream mobile app traffic to a PC client for real-time analysis on a larger screen. Connect easily via QR code or IP/port input for seamless teamwork.

Packet Import & Export
Export locally captured data in formats such as Session, HAR, and CSV for easy review later.
You can also import external capture files directly into the app for analysis.
Quick Actions
Easily copy any field content or decrypt data directly from the packet details view — faster and more efficient network debug and analysis.
Tools
Packet Capture Pro’s Tools module offers everything you need to streamline packet analysis and troubleshooting. It supports text encryption/decryption and multiple encoding/decoding formats including URL, Base64, Unicode, and MD5. You’ll also find practical utilities such as timestamp conversion, certificate hash conversion, regex testing, and QR code generation/ scanning.
All tools are built to match the actual needs of packet capture and network debugging—making your workflow faster, smoother, and far more efficient.
How it works
Packet Capture Pro iOS creates a local VPN on your device, routing all traffic through a local proxy server. When the VPN is active, it captures all Wi-Fi and cellular data traffic for comprehensive on-device data capture and inspection.
How about my sensitive data?
Packet Capture Pro uses a self-signed root certificate generated on your device. All captured request and response data stays on your device and is never sent to remote servers, ensuring your data privacy during every data capture and network debug session.

Capturing on Mobile Is Way Easier Than On PC

Some bugs only appear on specific devices or OS versions, which PC-based tools can’t fully capture. This app lets me capture everything directly on the phone, which is incredibly helpful for mobile devs dealing with device-specific issues.
Boosts Efficiency

The interface is clean and well organized, and the packet list is easy to navigate. Each request expands to show detailed information with accurate parsing. It’s great to be able to handle tasks on mobile that previously required a desktop setup.
Great App
