I'm looking around on internet for a good stylus and writing app to use on my tablet. but it looks that it all depends on the type of tablet.
I'm having a galaxy tab 2 10.1 do you have some info about writing on this tab?
By writing app do you mean handwriting recognition or a free hand notetaking solution?
The Stylus you choose makes all the difference in the world. Before I got my Note 10.1 I was also searching for a solution and tried many different types of Stylus. The only rubber tipped Stylus that worked well is the Pogo Sketch Pro, and I also found the Caseen Vibe and a couple New Trent models (the Caseen and Trent use some kind of fiber or foam or fabric). A standard rubber tipped Stylus skips and doesn't slide smoothly across the screen, making drawing or writing frustrating at best.
