Mega Voxels vs Voxel Builder

Mega Voxels is a mobile app for making 3D voxel art and 2D pixel art on Android and iOS. Its editors include a 3D voxel workspace and a pixel-art editor with Pencil, Bucket Fill, and Magic Wand tools. The installation guide describes a library of more than 450 voxel models and says users can create models up to 256×256×256. The app supports MagicaVoxel VOX files and OBJ export; the maker describes exports for use with tools such as Unity and Blender. It also says users can create and save video animations and view designs in augmented reality. The app download is free, and free content licenses are issued at no cost. Premium content licenses are available with a valid subscription, but each license applies to one design, and premium content cannot be copied, downloaded, or distributed as a standalone item. Weekly Premium costs $1.99 a month, Monthly Premium costs $4.99 a month, and Yearly Premium costs $49.99 a year. The maker identifies Go Real Games, LLC as the app's owner and operator.

Voxel Builder is a voxel-based 3D modeling application for creating and editing voxel scenes. It includes terrain, cube, sphere and isometric generators, alongside interactive modeling, symmetric drawing and painting, transforms and color groups. Rendering tools include a Three.js sandbox, GPU path tracer, basic PBR rendering and post-process effects. The app can voxelize GLB, OBJ, STL and PLY models, as well as images and Unicode or emoji text. It saves and loads JSON and MagicaVoxel VOX files, and exports GLB, GLTF, OBJ, STL and PLY. Local storage, snapshots, quicksave, undo and redo are available, with snapshot backups shareable in ZIP archives. A Blender importer script is included, and baked GLB meshes can be used with Blender and other 3D software. The project describes the app as portable and usable online or offline, with no ads, trackers or logging; its code is GPL-3.0. Browser use is supported on desktop and mobile, and Electron downloads are listed for Linux x64 and Windows x64.
