I use this app on my tablet(SM-P580) and i love it very much. I stick side my palm and I can write on pdf easly. But I can not do this with xodo for windows. Screen never be stable when i touched the screen for write on pdf with Spen. This application's android version is perfect optimized for Spen. Thank you very much for this. But i can not work on windows.
