Writing this review to let prospective buyers know the app is worth the cost purely on the brilliant work the dev has done on creating a great simulation in terms of using an ink brush on a digital medium on iOS. This will stand out against many similar art apps and therefore makes the app a joy to use and play with. Well worth the price! It also includes several backgrounds and a bare bones set up to allow you to concentrate on sketching vs troubling over too many options. However although there is a purposeful intent here to keep it simple and elegant? I do think some basic additions are in need here: 1) please allow zooming in of canvas to sketch in finer detail 2) if you will let users save the artwork as a photo, it would only make sense and be great if users could upload a photo to sketch on. I think this would be a favorite feature for many if added. 3)needless to say, limited color options and only one step in undo/redo is quite limited but if you must keep it so simple please consider allowing taskbar to auto-hide to maximize workspace, especially on the iPhone. Still, a great app and really great price for it while on promotion!
