Why pay for something you already have built-in?

With “Preview”, you can already add a signature to your documents (click on the toolbox). And the version in “Preview” is easier to use, since you do not need to click on your trackpad, just to swipe over it. Since you have to click and hold your trackpad here, the signature looks less fluid. At leats it is just a free version, so you can add it to play around and waste time, but this is basically it...
