The main benefit of a bug-tracking system is to provide a clear centralized overview of development requests (including both bugs and improvements; the boundary is often fuzzy), and their state. The prioritized list of pending items (often called backlog) provides valuable input when defining the product road map, or maybe just "the next release".
Captr helps you automatically create beautiful and detailed bug reports that are visual in nature which removes any ambiguity about the issue raised, simply, bugs get fixed quicker as they are easier to replicate.
