StochasticGrain vs KAMRA
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
StochasticGrain
Read full descriptionHide full description
Unlike simple noise overlays, this app uses a physics-based approach where grain density responds to image brightness, just like analog film. Shadows show more grain, highlights stay cleaner. The result feels organic rather than digital. Built on academic research by Newson, Delon, and Galerne (2017) modeling stochastic film grain through Boolean models, with real-time optimizations informed by Zhang et al.'s 2023 SIGGRAPH work. These papers describe how actual silver halide crystals distribute in photographic emulsion. Exposure-dependent grain that responds to image luminance Real-time preview as you adjust Designed for film photography enthusiasts A passion project for anyone who appreciates the texture of analog photography.
KAMRA
This app simulates the look and feel of analog film photography with realistic grain, halation, and color grading. It offers multiple film stocks and randomized effects for unique results with every shot.
- 8 hand-tuned film stocks
- Realistic grain structure
- True halation and bloom effects
- Randomized tone and light balance
- Live graded viewfinder
- Adjustable soft focus
- Multiple lens options

KAMRA. Film camera. No excuses. Eight hand-tuned stocks — Kodak Gold, Fuji C, Velvia, Ilford, Portra, and more. Each one built with its own grain structure, halation, colour curves, and shadow tint. Applied the moment you shoot. Grain that reads the light. Coarser in the shadows. Finer in the highlights. Animated every frame. Halation that bleeds warm and red from your highlights — not a glow filter. Physics. Every frame gets a randomized tone, light balance, and shadow depth. Same scene. Never the same photo. KAMRA shoots like film feels. — 8 colour-graded film stocks — Real luminance grain · ISO 100 to 3200 — True halation & bloom — Live graded viewfinder — Randomised light leaks per shot — Soft focus with adjustable bloom — 0.5× · 1× · 2× lens switching — Self-timer · flash support — Home screen widget

Verdict
The clearest difference is update cadence: KAMRA at every 3 weeks against StochasticGrain's every 7 months. StochasticGrain's advantage is iOS requirement (17.6 vs 26.2). On price, ads, in-app purchases and device support there is nothing between them.
