If you’re just referring to Blender sculpt mode then 100%. Tried out Nomad on my crappy old Samsung Note 4(I just use this a an Ebook at this stage) Performance was potatoe levels(as expected), but I just wanted to check the features and it’s very impressive.
I’m coming from a very long history of Zbrush use and I would go as far as saying that I would gladly purchase a brand new tablet/pen just to have Nomad available to me.
It’s unbelievably simple to use, very modern and artist-friendly UI(PBR/IBL/matcaps), has all the features and brushes you need - dynamic topology/multires/remeshing.
Clay brush feels decent, which is VERY important to me. In my opinion the Blender Clay engine isn’t up to scratch.
Having said all that, I only used the app in potatoe/fat finger mode so I can’t comment on performance or how the sculpting feels with a stylus/pen.
For the price though, Nomad might as well be free. You can install the trial and check it out yourself. If you have no sculpting experience and a good pad/pen then this is a perfect introduction to sculpting without the distractions of a full 3D program.
All you need are Clay/Move/Flatten/Dam_Standard(called Draw Sharp in Blender) brushes and you’re off. You can sculpt absolutely anything with these 4 basic brushes.
