PixVox simplifies the process of voxel modeling, allowing you to create detailed 3D voxel models from your photos or saved images with just a few taps. Imagine capturing an object in the real world and turning it into a voxel-based creation in minutes! Key Features: - Instant Voxel Creation: Generate voxel models easily from any 2D image. However, the subject in the image must clearly stand out from the background. - Versatile Export Options: Export your models in a wide range of formats, including .vox, .ply, .usdz, .stl, .glTF, .dae, .fbx (ASCII), and .obj. Whether you're working on 3D printing, game development, or any other creative project, PixVox has you covered. - Compatibility: Requires iOS 17 or later. - Optimized Performance: Tested for smooth performance on iPhone 12 Pro and 15 Pro models. - MagicaVoxel Note: Exported models adopt the default MagicaVoxel color palette, which may differ slightly from the original image colors within PixVox. Unlock your creativity and bring your voxel models to life with PixVox! Download now and start transforming your photos into 3D masterpieces.

Verdict
The clearest difference is ads: PixVox at none against Open3D's shown. PixVox also leads on rating (5.0 vs 4.8) and monetization model (free vs ad-supported). Open3D's advantage is update cadence (every 2 days vs fortnightly) and ratings volume (24 vs 2). On price, review sentiment and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
PixVox holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Open3D has 24 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
PixVox ships an update fortnightly, Open3D every 2 days. The most recent releases landed on October 24, 2026 and October 31, 2026 respectively.
