Continued Improvement
I purchased estroke at first version and Ive really enjoyed its continued improvement. Lots of interface tweaking, additions of various ways to categorize and save stroke examples. The dictionary input and showcasing seem faster now. This seems to be a developer who is willing to keep at it, and keep improving. This is not your first choice if you are trying to learn the language (check out Plecos excellent app), but if you are looking for a good way to study calligraphy with a cross-reference to standard Mandarin traditional and simplified characters, this is very very good. I have this open on my iPod Touch when I sit at my calligraphy table!
