Capturing on Mobile Is Way Easier Than On PC
Hesfhitdxhji
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.
Great App
Rom Wali
The interface is clean and professional, and beginners can pick it up quickly. Once packet capture is enabled, the data is clearly organized, and the search/filter functions make debugging much faster.
Extremely Practical
Omer Fisher
The packet list is well-structured, and you can view details with just one tap. Parameters are displayed clearly, making it intuitive to debug slow requests, inspect retry logic, or check headers and bodies.
1.Added Cookie Jar to the debugging tool, with support for automatically storing, managing, and sending cookies.
2.Added a new debugging settings page, allowing you to customize the configuration to suit your needs.
