When you work on a big project or on a computer program, it is highly advisable to use a flowchart to be able to make sure that the work has been done properly. In these cases one of the free software applications that you can use is FreeDFD.
Flowcharts from your PC
The interface of FreeDFD is rather dull, and many users that it is somewhat outdated if compared to the programs that are currently available, but it allows the possibility to create the flowcharts in a very clear way.
What's more, if you want to create a subroutine for any part of the project, FreeDFD will allow you to create it on another page in such a way that you can return to the main page once you have finished it.
Create flowcharts very easily.
On the other hand, due to the fact that FreeDFD has been created to check mathematical calculations and the good working of computer programs, its debugger can be used to check both types of flowcharts.
