Mobile Art is a technology based art form, and refers to art created on a mobile device, whether that be a smartphone or tablet. Some artists paint on their mobile devices, others create collage works, others start off with or incorporate stock images, while others begin by capturing their own images on their devices. Some artists start off capturing an image on their phone and then edit it on their tablet.  In all instances the use of a variety of apps is part of their process.   

I have chosen to create my artworks entirely on my iPhone - I capture my own images on my iPhone and then edit them on my iPhone using apps - For these reasons I use the term iPhoneart which I consider a sub-category of Mobile Art.
