As much as I love Procreate in Apple, PENUP is one of the best apps to create, to illustrate what's going on in my mind at anytime and anywhere. I love the texture of the tools, particularly, the pencil, the sound and the simplicity of the apps. I can draw and create anytime and anywhere I want. No need to bring my 11inch ipad pro(too heavy for me). No lah just joking, too lazy to bring my ipad haha lol.
