AppScope is described as 'tool for networked mobile applications to instantly capture comprehensive bug reports containing screen video, network data and system logs' and is an app in the Development category. There are five alternatives to AppScope for a variety of platforms, including Mac, Windows, Linux, iPhone and iPad. The best alternative is Wireshark, which is both free and Open Source. Other great apps like AppScope are Fiddler (Freemium), mitmproxy (Free, Open Source), Charles (Paid) and Surge for Mac (Paid).
Wireshark is the world's foremost network protocol analyzer. It lets you capture and interactively browse the traffic running on a computer network. It is the de facto (and often de jure) standard across many industries and educational institutions.
Fiddler is a Web Debugging Proxy which logs all HTTP(S) traffic between your computer and the Internet. Fiddler allows you to inspect all HTTP(S) traffic, set breakpoints, and "fiddle" with incoming or outgoing data.
Charles is an HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet. This includes requests, responses and the HTTP headers (which contain the cookies and caching information).
Working quietly on the Menubar, Surge is a high-performance HTTP/SOCKS5 proxy server. It is capable of intercepting and logging the summary of HTTP traffic, and meanwhile transmitting the traffic to other proxy servers according to the flexible rule system.
