I have been looking for an Android calligraphy app for quite a while. Today, I downloaded the two Autodesk Sketchbook apps as well as the INKredible handwriting app. The Sketchbook app has a broadedge tool, but the edge is not very sharp, so the thin angle is not good. So I moved onto the INKredible app from an minor developer, not expecting much. The basic app is free with the calligraphy tool for $0.99 extra. Below is the image of what I could do with a fat stylus.
The fountain pen tool could work for pointed pen hands. The downstrokes are thicker than the upstrokes, with the difference set by the "wetness" scale. I think this has possibilities!
I bought the calligraphy tool, which is a broadedge. The angle of the edge is adjustable as is the wideness. The thick to thin is good!
There is also a brush pen tool to buy for $0.99. I will let someone who knows about brush pens review that. There are also guideline papers to buy for $0.99.
Finally, your final products can be saved as images or as .pdf.
All in all, a nice little app for a reasonable price. I would love to see what other people can produce.
