Depth3D converts local MP4 and MOV videos into stereo side-by-side 3D video using on-device AI depth estimation. Import a video, and Depth3D processes it entirely on your device to generate: • A depth preview video • A stereo side-by-side (SBS) video for compatible 3D viewers and displays • Raw depth data (.npy) for advanced workflows After depth data is generated once, you can adjust stereo strength or output resolution and regenerate the stereo video without recomputing depth. All processing happens on-device. No uploads. No servers. No account required.

Verdict
The clearest difference is in-app purchases: Depth3D at none against World Palette's 1. Depth3D also leads on update cadence (every 11 days vs every 5 months) and iOS requirement (15.0 vs 17.6). On price, ads and device support there is nothing between them.
