Stinkbug PM

Solo software developers and developers with side-projects have needs for project management tools, but those needs differ from the features provided by most conventional tools. Conventional tools focus on collaboration, communication, and coordination between teams of individuals, but solo developers primarily need to communicate with their future selves.
Stinkbug is a tool that is designed for the solo developer.
It enables you to track your projects, multiple versions and multiple builds. It understands that a project may have several deliverables and use a number of dependencies. And it may be deployed to multiple target environments.
An issue tracking system is integrated into project management. The issue tracker is used to track bugs, feature requests, etc. But it is also used to generate a to-do list of work to be accomplished with each version.
The issue tracking system tracks each issue from when it was first reported, through data gathering, analysis, coding and testing to final closure. It supports attachments of many kinds (including text, logs, pdfs, images, videos and more). You can record who reported a particular issue and communicate with them via email from inside the application.
In addition to the project tracker and issue tracker, Stinkbug also includes a programmer's journal. The journal provides you with a place to "think out loud", to reflect on what you did and to learn from your successes and failures.
Stinkbug is highly customizable and does not try to bind you to any particular project management methodology. You can use as many or as few of its features as you need.
It runs on Macintosh, iPhone, and iPad and synchronizes data between devices, so that it is always there when you need it.
And best of all, it is completely free.
