LUT Lab
Apple Log preview and color export for iPhone and iPad.
LUT Lab lets you open Apple Log footage, apply a LUT, and export a color-graded clip — entirely on your iPhone or iPad. No desktop required for the workflow.
The public App Store URL was not available at publish time, so this page is live with a support contact instead of a broken store link.
