Cytosphere
Thirteen generative wallpaper patterns drawn from real biology, chemistry, and physics. Rendered natively at up to 16K. No AI. No tracking.
Features
Wallpapers that mean something.
Every pattern is a procedural composition. Same look, same seed → same wallpaper. Change the seed, get an entirely new arrangement. Thirteen patterns × infinite variation = a wallpaper you've actually never seen before.
Thirteen generative patterns
Mitosis, hematopoiesis, atomic orbitals, viral capsids, electric fields, molecular structures, and more. Everything procedural — no stock images.
Fine-grained controls
Hue, saturation, density, depth-of-field, element scale, opacity. Live preview re-renders instantly as you tweak. Save your favorites as presets.
Up to 16K export
Pick a square ratio for desktop or portrait for iPhone/iPad lock screens. Standard 6K, High 10K, or Ultra 16K — even on a Pro Display XDR you'll have pixels to spare.
Privacy-first
No accounts. No ads. No analytics. The app makes no network connections of its own — every wallpaper is rendered entirely on your device.
Native Swift renderer
Pure CoreGraphics. No Electron, no web view, no Metal compute kernels. Tiny app, fast launch, low battery cost.

Privacy posture
What we collect: nothing.
