Based on the details found on the official website, the application is on a Shareware license, which means you can test it for 7 days, and then it needs purchasing. No, SmartDraw is not a free application ,because it needs to be bought in order to enjoy the full version.
I downloaded the installation package and was greeted with the image you see below. I have 7 days to test it, and then it won't work anymore.
