In contrast to method profiling, which tells you how frequently a method is being called, method tracing helps you to also determine its input and output values. This technique can prove to be very useful when dealing with applications that have a big codebase and/or are obfuscated.
As we will discuss shortly in the next section,
frida-trace offers out-of-the-box support for Android/iOS native code tracing and iOS high level method tracing. If you prefer a GUI-based approach you can use tools such as RMS - Runtime Mobile Security which enables a more visual experience as well as include several convenience tracing options.
