Voxel Max for IOS Ipad
A very interesting and efficient Voxel sculpting program. You can use different materials like metal and emissive materials.
Objects and scenes can be exported to OBJ, FBX, Qubicle, Magica Voxels Vox and more.
Objects can be up to 256 x 256 x 256 and a whole scene with objects can be much bigger. https://voxelmax.com/ https://voxelmax.com/r/install/appstore
Don't worry I'm not one of the isheeps ;-). Unfortunately there a some apps that simply doesn't exist on Android. And the Ipad Pro is actually not that bad.
Maybe it could be a comfort for you that Nomad Sculpt is available for Android now as well as ios.
The French guy Stéphane Ginnier makes fabulous progs with very attractive UI!
Exists in free online or local as Sculpt GL ! ;) https://stephaneginier.com
