What it does
Most editors give you one filter for the whole image. Prism gives you a graded set: pick Ember and your five strips run from cool ash to deep amber in sequence. The pieces still line up into your picture, but now it reads like light through a prism. Pick a photo, tap a template, set it as your wallpaper.
- Slice any photo vertically, horizontally or diagonally, into 2 to 10 strips.
- Four graded sets, 20 film LUTs. Ember (warm film, cool ash to deep amber), Tide (cool cinematic), Neon (a full spectrum) and Silver (toned monochrome). All hand-built and exclusive to Prism.
- Tune any single strip by hand: swap its tone, dial its strength, adjust intensity and hue drift.
- Drag and pinch to position the photo behind each cut.
- Live lock-screen preview, so you see it before you set it.
- Collage mode blends up to 10 photos into one wallpaper.
- Import your own 3D .cube LUTs.
- Nothing leaves your phone. No account, no internet, no sign-up. Full-resolution export straight to Photos.

Questions
What is a LUT, and why does Prism use them?
A LUT (look-up table) is a colour grade applied per pixel, the same tool film colourists use. Prism ships 20 original LUTs and can assign a different one to each strip of a photo, which a single whole-image filter cannot do.
Does Prism upload my photos?
No. Everything is processed on the device. Prism has no account, no analytics and does not use the internet.
Can I use my own LUTs?
Yes. Prism Pro imports standard 3D .cube files of any size.
Is Prism Pro a subscription?
No. Pro is a single purchase through Apple.
Does the exported wallpaper look like the preview?
Yes. The preview and the export use the same rendering pipeline, and the export is full resolution with no watermark in Pro.
