## What is Graphica Playground?

Describe it. Ship it.

Graphica Playground turns one sentence into a Metal shader you can actually use. Write what you want to see, watch it run full screen, tune it until it feels right, and take the code straight into your SwiftUI project.

Built for designers, design engineers and iOS developers who want distinctive backgrounds, glows, ripples and gradients without writing shader math from scratch.

GENERATE FROM WORDS
- Type a description like "deep ocean caustics with drifting light" and get a live, animated Metal shader
- Every result is compiled and checked on your device's GPU before you see it; broken or blank output is automatically repaired or replaced
- Not quite right? Use Refine to describe what to change, and keep your colors and settings

TUNE IT LIVE
- Adjust speed, intensity and scale in real time
- Pick from curated color palettes
- Touch the preview and the shader reacts under your finger
- Tuning never re-runs the AI, so you can experiment as much as you like

EXPORT CODE THAT MATCHES THE PREVIEW
- SwiftUI: a .metal file with a stitchable function plus a ready-to-use SwiftUI view built on .colorEffect
- Metal only: just the stitchable function for ShaderLibrary
- MTKView: runtime-compiled Metal source with an MTKView renderer
- Copy to the clipboard or share the files
- The preview and the exported code are built from the same shader, so what you see is what you ship

LEARN SHADERS BY WRITING THEM
- Lessons on coordinates, color, distance, rings, soft light and noise, one expression at a time
- Your picture is checked against the target as you go, and most steps need no typing
- Open a finished lesson in the editor to see what each slider changes

START FROM PRESETS
Hand-built starting points such as Liquid Glass, Mesh Gradient, Metal Ripple and Ripple Field.

YOUR LIBRARY
Every shader you generate is saved automatically. Search, mark favorites and pick up where you left off.

SHORTCUTS AND SIRI
Generate a shader, open one, adjust its parameters or get its code from the Shortcuts app, Spotlight or Siri.

PRIVATE BY DESIGN
- No account and no sign-in
- Your prompts and shaders stay on your device, unless you connect your own model endpoint
- On-device generation uses Apple Intelligence on supported devices
- Offline templates always work, even in Airplane Mode, so generation never comes back empty
- Prefer your own model? Connect any OpenAI-compatible endpoint with your own API key (Pro). The key is stored in the iOS Keychain and sent only to the endpoint you choose

FREE
- Up to 10 generations a day
- 3 saved shaders
- 4 presets
- The first 2 lessons
- Full live preview, touch interaction, speed, intensity, scale and curated palettes

PRO
- Export and copy code
- Unlimited generations and unlimited saved shaders
- Set all three colors by hand and tune the touch response
- All 8 presets, including Nebula Warp, Crystal Cells, Vortex Rings and Particle Dust
- Version history: return to any earlier take
- Use your own API key
- Every lesson, including new ones as they are added

On-device generation requires iOS 26 or later on an Apple Intelligence-capable device with Apple Intelligence turned on. On other devices the app uses offline templates.

## Version history (last 5 releases)

### 1.3.1 — 2026-10-09

Purchase fixes.
- If you bought Lifetime, Settings no longer shows a Manage subscription button that had nothing to manage.
- Settings and the Pro screen now link to the legal notice required in Japan.

### 1.3.0 — 2026-10-07

Made for iPhone Duo and wider screens.
- On an open iPhone Duo, the Learn list and lessons sit on either side of the fold. Lessons scroll the explanation and preview separately from the code and hints.
- The preview on the Create screen now reaches the screen edges, and recent shaders and presets show larger on wide screens.

### 1.2.1 — 2026-10-03

A friendlier Export screen.
- Each file's how-to now lives behind a How to use button, so the code gets more room.
- Copy the file you're viewing from the top-right of the code, or every file from the button below.
- Settings now shows when the on-device model is still downloading and when it's ready.

### 1.2.0 — 2026-10-02

New: the Learn tab. Four hands-on lessons teach Metal shaders by changing one expression at a time in a real shader, with your result checked against the target as you go.
- Coordinates and color, and Circles and rings are free. Soft light, and Noise and patterns come with Pro.
- Sliders, multiple choice and tap-to-arrange pieces, so most steps need no typing.
- Touch a canvas to read its values, see where your picture differs from the target, and open the finished shader in the editor.

Also: Settings now opens from the gear button, primary buttons are easier to read, and the English text uses US spelling.

### 1.1.0 — 2026-09-29

Graphica Playground now speaks Japanese. On-device generation is also more reliable: broken expressions are caught earlier and redrawn.
