I just watched the demo.
It seems like a few templates in an app with the ability to change content and publish trough FTP.
I don't know what your needs are but it's definitely a beginners app. What i mean is that I doubt you'll be able to change the template a lot. Unless you have HTML+CSS "access" but if that's the case why not just use Notepad++
It has trial version. Test it!
I'd still go for themeforest if it's my personal site and I need it fast.
Just a thought...
