Zen Brush is a beautiful little app with only one step of undo and no way to save anything in its original format. No layers, the eraser is very primitive and does not help much, so best to leave it alone and pretend it’s not there at all. One black brush, two translucent gray brushes and an option to change the brush size. All brushes are round and look more and more like painting wet on wet as their sizes grow. That’s it. The app would be almost like a Zen board where your creating is gone forever unless you were quick enough to take a photo. Similarly, Zen Brush has an option to export the drawing as a PNG file.
Lovely thing for quick sketches.
My first semi-serious attempt to do a more than a rudimentary sketch in ArtFlow app. You know what’s the best part of working in it? It saves all changes automatically and seemingly in real time, at least I haven’t lost anything yet. And I think if I ever hit the limit on the number of layers in the file it will be my phone’s fault, not the app’s.
