Downloading TidyCards 1.0.7 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. We recommend checking the downloaded files with any free antivirus. The software lies within Productivity Tools, more precisely Timekeeping. This free Mac application is a product of Joseph Williamson.
From the developer:
TidyCards is a personal project planner that integrates with your e-mail, files, and calendar. The tool is designed to help you track all your tasks and information to streamline your work. Not only can you keep track of what you need to do, but also you can link to your e-mails, files and calendar events, so you spend less time searching and more time doing.
