This app is the worst.

It disguises itself as free but as soon as you download - you find out that this is just a free version so you get acquainted with the program and buy the full version. Please notice that there`s no indication of this in the name or anywhere, so in the App Store you think you`re downloading a free version.
Just use MacDjView - works like a charm and is free and open source.

I hate these cheap tricks. Author of this disgusting piece of crap - please choose a different job, don`t disgrace a developer`s profession.
Cheers!
