Gaussian SplatKing
Mobile Gaussian Splatting
Free · In‑App Purchases
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.
more 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.

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.

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

SplatKing 1.6.2 speeds up on-device training.
• Train Splat (SplatKing Pro) now trains faster on iPhone.
• Capture, exports, and the trained .spz format are unchanged.
1.6.2 4h ago
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.
1.6.1 Oct 22
SplatKing 1.6.0 adds a processing stage after capture and introduces SplatKing Pro.
• Pose refinement — after a LiDAR capture, camera poses are refined on the device (feature matching and bundle adjustment) and recorded in the export. Free for everyone.
• Train Splat (Pro) — train a Gaussian splat from a refined LiDAR capture on the device. Output is an .spz file; view it in the app or share it.
• SplatKing Pro — a one-time purchase that adds focus peaking, an RGB histogram, capture presets, the auto-capture interval selector (1, 2, 5 or 10 s; free capture stays at 1 s) and on-device training. Free capture quality is unchanged.
• Tips — optional Coffee, Lunch and Dinner tips. They unlock nothing.
• Settings → About → Acknowledgements lists the open-source components the app ships.
• The Support Development link is removed.
• Accessibility — the analytics notice follows the system appearance; session quality pills carry Good / OK / Poor words; the live quality HUD shows G / O / P letters when Differentiate Without Color is on.
• Fix — a dual-lens photo series no longer fires a queued auto pair after the series has stopped.
1.6.0 Oct 20
New in 1.4.1
Reliability
• Fixed a first-run issue where the “Got it” button on the analytics notice could be untappable on Zoomed display settings, which left the app unusable. The notice now scrolls and the button stays reachable.
1.4.1 Aug 6
New in 1.4.0
• Save GPS Location — optionally record where each capture was taken. Off by default; turn it on in Settings.
• Single-lens capture & RAW — choose 1x single-lens capture for Photo and Video, and shoot RAW (DNG) photos in single-lens mode.
Reliability
• Fixed a capture crash affecting single-camera iPhone models.
1.4.0 Jul 8
This update adds optional anonymous analytics to help us improve capture reliability. Events are anonymous and range-bucketed — never your captures, filenames, or location. In the EU/UK and other prior-consent regions, analytics is off unless you turn it on; elsewhere you'll see a one-time notice and can turn it off anytime in Settings.
Also fixed: setting a backup folder from Settings now works reliably, the backup row updates immediately after changes, and removing a backup location makes clear your files are never deleted.
1.3.0 Jul 6
iPad support with portrait and landscape layouts; capture on single-rear-camera iPads; preview rotation and stale-frame fixes
1.2.0 Jul 2
Fixes an issue where manual camera controls (shutter, ISO, white balance, exposure) could revert during extended or warm captures.
1.1.1 Jul 1
This update adds single-camera capture and a broad set of reliability improvements.
• Single-camera capture: iPhones with a single rear camera can now capture photo series and video on the wide lens. Devices with the dual 0.5×/1× system are unchanged.
• Captures hold through interruptions: an incoming call or another app using the camera no longer ends a photo series.
• Better handling under heat and on long sessions, with a clear notice when the device needs to cool and automatic resume once it does.
• Steadier manual controls and sturdier exports: control changes that can't be applied now revert cleanly, and sharing and file cleanup are more robust.
1.1.0 Jun 26
This update improves the reliability of photo capture and manual camera controls and hardens capture export. No changes to capture formats or output.
1.0.7 Jun 21
• Video and LiDAR captures are preserved if a session is interrupted, backgrounded, or ends unexpectedly — including LiDAR scans interrupted mid-capture, which now save as a complete segment.
• Long recordings stay stable under heat and low storage, reducing frame rate gradually and warning before storage runs out.
• Capture export now verifies the archive before removing the originals.
• Fixed a rare crash during photo capture after the camera recovered from an interruption.
1.0.6 Jun 14
- Recordings are now written with periodic checkpoints. If a capture is interrupted, a force-quit, a crash, a dead battery, the footage survives up to the last few seconds instead of being lost.
- Both lens streams are verified after every recording. If a file didn't save correctly, SplatKing says so and reports what's recoverable, instead of reporting success.
- Overheating no longer ends recordings abruptly. The frame rate steps down (30 → 24 → 15 fps) to keep recording under thermal pressure and restores as the device cools; stopping, with footage saved, is the last resort.
- Running low on storage during a recording now warns ahead of time, then stops and keeps your footage.
- ZIP export checks free space before starting and tells you exactly how much is needed, with the option to export the folder directly instead.
1.05 Jun 12
This update focuses on capture reliability:
• The live preview now recovers automatically if the camera is interrupted mid-capture — it no longer stays black while photos keep saving.
• Fixed a preview freeze that could occur when switching capture modes quickly.
• Auto-capture eases its rate when the device gets warm, reducing thermal strain on long sessions.
• Auto-capture now pauses under low memory to prevent an abrupt interruption.

SplatKing 1.0 redesigns the capture interface and expands manual control, and adds native COLMAP export from LiDAR.
• Redesigned capture interface. A control rail with on-chip readouts replaces the old HUD; every active setting shows its value at a glance.
• Focus controls. AF Lock, manual focus distance, and tap-to-focus, applied across both lenses.
• Minimum shutter speed. Set a shortest-exposure floor to hold sharpness during motion. Available in photo and video.
• Manual controls can remember your last settings. Optional; exposure and white balance carry over between sessions.
• New Settings page. Grid overlay, haptics, and a launch-in capture mode.
• LiDAR captures export a COLMAP text model. Cameras, images, and sparse points, written on-device and ready for reconstruction pipelines.
• Landscape support on iPhone.
• Photo and video still capture the 0.5× ultra-wide and 1× wide lenses simultaneously; LiDAR pairs ARKit depth with the 1× wide lens.
