I discovered this excellent app after seeing the new 3DS version release. I downloaded this app on my 3rd generation iPad; thats when I instantly noticed a few things. I dont mean to sound negative right out of the gate, but if it werent for the few items I address below, this app would be truly top notch. And for the relatively high (among its peers) price of $4.99, I really wish some of the things I mention would have been addressed at this point. I was not anticipating compatibility issues in this price bracket.
The first thing I noticed was that this version of the application cannot view the drawing process or save a lot of the newer art published on the online gallery. I assume this is because the newer art is coming from the 3DS version of the application and is not currently compatible until the iOS version is updated.
The other issues I have are related to presentation optimization. This application does not support the retina display on iPhone, and there is not an iPad version (or just iPad compatibility). For these couple of reasons I cannot give this a full 5 star rating.
Having said that, all other aspects of this application are excellent. From the intuitive, simple methods of controlling the size or opacity of the brush by tilting the device, to the fantastic re-rending process of your art, I am very pleased with this as an artistic application. I find that in its simplicity, its prowess as an easy way to draw beautiful art is exposed almost immediately.
I would like to commend this app as an artistic tool, and I would really love to see it move up in compatibility with its own medium formats and the current slate of iOS devices and their capabilities. If it can do that, Ill immediately give it a 5 star review.
