Get your Kaggle API token
- Sign in to kaggle.com with your own account (it is free). Kaggle asks for a phone-verified account before it gives GPU time.
- Open kaggle.com/settings, find the API section and tap "Create New Token".
- Copy the token (it starts with KGAT_) and paste it in Splat Lab when you choose to train on Kaggle. It is checked once, then kept in your iPhone's Keychain.
- To remove it: Settings (Réglages) in Splat Lab, then Forget (Oublier) next to your Kaggle account. You can also revoke the token on kaggle.com/settings at any time.
Splat Lab Station for Mac
Splat Lab Station is the free Mac companion that trains your scenes on your own computer, over your local Wi-Fi. It is coming soon on the Mac App Store.
Once it is installed: open it on a Mac on the same Wi-Fi as your iPhone, choose "On my computer" (« Sur mon ordinateur ») in a scene, and type the 6-digit code shown on the Mac.
Tips and monthly support
Tips and the monthly "Un café par mois" support are optional in-app purchases handled by Apple. Tips unlock nothing; the monthly support only adds supporter app icons and a badge. Every feature is already included. Cancel the monthly support in your App Store account settings; for a refund, use reportaproblem.apple.com.
Common questions
My scene looks blurry or has holes.
Film again more slowly, walking around the room rather than turning on the spot, with steady light. Look at the floor too, and avoid mirrors and windows. Training on your Mac or on Kaggle usually gives a sharper result than on the iPhone.
Where are my files?
In the Files app, under On My iPhone › Splat Lab. Exports are there too.
I closed the app during Kaggle training.
That is fine. Kaggle keeps training; Splat Lab sends a notification when the splat is ready and downloads it the next time you open the app.
Do I need an iPhone with LiDAR?
No. Splat Lab uses the camera and ARKit's motion tracking, which work on iPhones without a LiDAR sensor.
Is it free?
Yes. Splat Lab is free, with no ads, and no feature is locked. You can leave an optional tip, or support it monthly for a few cosmetic extras (supporter app icons and a badge).
Where does the training run?
Where you choose, for each scene: on the iPhone itself (offline, nothing leaves the phone); on your own Mac with the free companion Splat Lab Station, over your local Wi-Fi after pairing with a 6-digit code; or on your own Kaggle account, which gives a free cloud GPU.
How does training on Kaggle work?
You paste your own Kaggle API token once; it stays in your iPhone's Keychain. Splat Lab uploads the capture to your Kaggle account as a private dataset, runs a private notebook there, downloads the finished splat, then deletes the dataset and the notebook. You can close the app while Kaggle trains: you get a notification when it is ready and Splat Lab fetches the result when you come back. Kaggle's own quotas and terms apply.
What can I export?
SPZ (a compact splat), PLY (the common splat format) and OBJ (the collision mesh: floor and walls). Exports are saved in the app's folder in Files and can be sent anywhere with the share sheet.
What is a Gaussian splat?
A 3D scene made of many small, soft, coloured blobs, optimised from your video frames so that the room looks real from new angles. It is what lets you walk inside a place you filmed.
Does Splat Lab collect my data?
Your captures, splats and exports never reach us. The app sends anonymous usage statistics (for example: a training finished, and where it ran) so we can improve it, and you can switch them off in Settings. Details are in the privacy policy.
Still stuck?
Tell us your iPhone model, the iOS version and where you trained (iPhone, Mac or Kaggle). A screenshot helps.
