Planix is an application that helps individuals and companies estimate specific elements of their projects. Planix can find estimates for your team to help them become organize and find defaults and issues. Planix’s estimate tool works by using COCOMO )constructive cost model) Function point analysis, and case points. You can estimate ranges, staffing, granular costs and language implementation by seeing best and worst case scenarios. There is a "what if" tool which can compare different project scenarios to see which ones are the most useful and efficient. The solo version of Planix is free but only allows you to have one active project at a time. There are five other upgrading options that range from $12.95 per month to contacting for further information and rang from two active projects to unlimited active projects.
