Gaussian SplatKing is a capture app for Gaussian splatting and radiance field reconstruction. It produces reconstruction-ready input data for any downstream pipeline and, for LiDAR captures, refines camera poses and trains a Gaussian splat on the device.
Capture
• Photo and video fire the 0.5x ultra-wide and 1x wide lenses simultaneously. A single-lens (1x) option, with RAW (DNG) photo capture, is available in Settings.
• LiDAR mode pairs ARKit depth with the 1x wide lens, writes native COLMAP files (cameras, images, sparse points) on-device, and shows the point cloud as it accumulates.
• 4K/30 HEVC video with Standard and Max Fidelity modes; optional undistorted video exports.
• Auto photo cadence for walk-through capture, with a selectable interval.
• Manual controls applied to both lenses: ISO, shutter speed or shutter angle, white balance, exposure, AF Lock, manual focus distance, tap-to-focus; a minimum shutter speed.
• Optional capture location metadata, off by default.
• iPhone and iPad.
Process
• Pose refinement: after a LiDAR capture, camera poses are refined on-device (feature matching and bundle adjustment) and recorded in the export. Free for everyone.
• Train Splat (SplatKing Pro): train a Gaussian splat from a refined LiDAR capture on the device. No upload, no account. Output is an .spz file with an in-app viewer.
Export
• Every capture is a zip with media, metadata, COLMAP files where applicable, and splatpack.json, shared through the Files app or the share sheet to any pipeline.
• Session quality summaries and per-file quality flags.
SplatKing Pro is a one-time purchase that adds focus peaking, an RGB histogram, capture presets, the capture-interval selector, and on-device training. Everything that is free today stays free, and Pro never changes free capture quality.
Analytics are anonymous and, in regions that require consent, off unless you opt in. Capture content never leaves the device unless you share it.
Really amazing capabilities for capture but could really use some support or videos on how to use the many output formats. Totally confused about what to do with so much data you get from the app other than the photos and video.
Best Capture App for iPhone

I’ve tried a handful of apps for capturing Gaussian spalts, but this one is easily my favorite. The dual lens video mode is really nice, but also really like the lidar+photo auto mode. Really like what you’ve built and look forward to seeing what comes next and maybe some guides for best outputs on Windows.
My favorite splat app

Haven’t seen any apps like this before letting me record with multiple lenses at once. It’s been great for my workflow!
Splat King!

Great tool for Gaussian splatting. 5 stars.
SplatKing 1.6.1 is a stability update with one new video setting.
• Fixes a crash that could occur when the system tore down the capture screen while a LiDAR series was open.
• A LiDAR capture interrupted before it finished processing is now recovered automatically the next time the app launches, and finalized in place.
• Settings no longer reset when the app is launched cold. Lens Mode, Video Quality, Photo Format, the last-used capture mode, and the display and Pro overlay toggles now persist as set.
• New: Video Resolution in Settings → Output. Record Video mode at 4K (the default) or 1080p, at 30 fps. Photo and LiDAR captures are unaffected.
