Overview

Granñe turns the iPhone into a film camera. Every look is a complete recipe: color response baked into a 3D LUT, plus grain, halation, vignette and softness rendered as separate passes in a real-time Metal pipeline. What you see in the viewfinder is the developed image.

The interface is deliberately quiet: one accent color, one repeated control skeleton, everything collapsible. Films are organized by what you are shooting (portraits, neon nights, mountains, chrome) and every look can be faded with a single intensity slider.

What we did

  • 28 data-driven film looks with a mathematical separation audit
  • Real-time Metal + Core Image render pipeline, preview and capture from one path
  • StoreKit 2 monetization: trial, subscriptions, lifetime
  • Video with the same looks, re-developing (REFILM), library import
  • Full App Store operation: ASO, screenshots, review process
