I saw a webpage from Samsung that listed some of the apps that support S Pen and some that would be released soon so here’s the complete list and I would appreciate someone else adding to this information
Official : Samsung S Pen supported Apps Page
Note: all the apps mentioned in above link are only available from Samsung Apps store inside your Galaxy note , so you need to set it up first , of those mentioned on the above web page at Samsung, the best one is
ZenBrush
It has a awesome feel and when you use it , it feels like you are painting with a real brush , it has very few features like size of brush , color of brush and a single step undo , but a very powerful feature of background templates which have yellowish paper , sky , autumn leaves etc. makes it a overall wonderful free S Pen drawing app
While the best app for sketching on Galaxy note is still SketchBook mobile from AutoDesk ( makers of famous Autocad software)
but , the irony is it’s not free but for those who are willing to pay this one is the best ! Will write more on S Pen and will try to code something with the S Pen SDK in future !
Would love to here from you...
