FRMT is the most accurate film simulation on the App Store. Here is why that is a real claim and not marketing. Most film apps are filters. A filter is a lookup table. It takes the color of a pixel, swaps it for a different color, and that is the whole trick. Same color in, same color out, every time, no matter what is around it. Film does not work like that. Light scatters sideways through the emulsion. Each dye layer chemically holds back the layers next to it. Dye forms in clumps, and how much forms depends on how much light hit that exact spot. What a pixel becomes depends on everything around it. FRMT simulates that, stage by stage, on every frame you shoot. WHAT IT ACTUALLY DOES Halation. Light passes through the emulsion, bounces off the film base, and exposes it again slightly off to the side. Bright edges bloom instead of stopping dead. Interimage effects. Developing dye releases a chemical that drifts sideways and holds back its neighbors. This is most of what gives a stock its color signature, and it is why reds stay clean next to greens. Real grain. Not a texture laid on top. Grain here is the actual variation in how much dye formed, so it follows the tones. Strongest in the midtones, almost gone in deep shadow, the way it works on the real thing. The curves and the numbers come off the manufacturers' own published datasheets. Nobody eyeballed a preset. FOUR STOCKS Cinnabar 50. Punchy and saturated. Landscapes, foliage, sunsets. Galena 100. Neutral and even. Travel, streets, mixed light. Baryta 100. Soft and fine grained. People, portraits, overcast days. Flint 64. Grainy and warm with cool shadows. Street, hard light, neon. You load one at a time, the way you load a roll. There is no look picker on the capture screen and there are no sliders. None of the four is a preset of another. HOW IT WORKS Press the shutter and a RAW negative is written immediately. Developing happens afterward, in the background, and takes about a minute per frame. That is not a loading spinner, it is real work on the GPU. Frames wait on the roll until they are done, and you can set developing to hold until you are plugged in. Finished photos save to your photo library and stay in the app, so you can look at them without leaving. You can also import RAW files you shot on something else and develop those. NO SUBSCRIPTION, EVER Pay once. No account, no cloud, no ads, no watermark, no in app purchases. Your photos never leave your phone. There is no networking code in the app at all. WHAT TO EXPECT The viewfinder shows you the scene, not the film. Grading a live preview means guessing at the answer, and a preview that guesses wrong is worse than one that is honest. Use the exposure dial to place your highlights. This is slide film. There is not much room above the highlights. That is faithful, not a bug. Requires an iPhone that can capture ProRAW. ## Key features - Accurate film simulation - Halation and interimage effects - Real grain simulation - Four distinct film stocks - RAW file development - No subscription or ads ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/frmt-film-simulation/id6800928630/reviews.md ### 3/5 — 我的设备不支持Apple ProRAW，但连进入都无法做到 *2026-09-05* 我原以为即使不支持Apple ProRAW，也是可以导入其他设备拍摄的raw来使用的，但是彻底不支持进入，并且没有试用就要求直接买断，决策成本有点太高了 ## Frequently asked questions about FRMT ### What makes FRMT's film simulation accurate? FRMT simulates real film processes like halation, where light scatters and blooms bright edges. It also replicates interimage effects, where developing dyes influence neighboring layers, and generates real grain based on dye variation, not just a texture overlay. ### Does FRMT have ads? No, FRMT is completely ad-free. The app is designed for a focused user experience without any advertisements interrupting the creative process. ### What are the four film stocks available in FRMT? FRMT offers Cinnabar 50 (punchy, saturated), Galena 100 (neutral, even), Baryta 100 (soft, fine-grained), and Flint 64 (grainy, warm with cool shadows). ### Can I import my own RAW files into FRMT? Yes, you can import RAW files shot on other devices and develop them within FRMT to apply its accurate film simulations. ### How long does developing take in FRMT? Developing each frame takes about a minute and is performed on the GPU. Finished photos are saved to your photo library and remain accessible within the app. ### What devices is FRMT compatible with? FRMT requires an iPhone that can capture ProRAW. It is currently supported on iPhone devices. ### Is FRMT a subscription service? No, FRMT is a one-time purchase. There are no subscriptions, in-app purchases, or recurring fees associated with using the app. ### What is the age rating for FRMT? FRMT has an age rating of 4+. This indicates it is suitable for a wide range of users, with no mature content. ## Version history (last 4 releases) ### 1.1.1 — 2026-09-02 Fixes a bug where the roll could not be opened until a photograph had been taken in the same session. The roll now also shows your latest developed frame the moment the app opens. ### 1.1 — 2026-08-27 FRMT now speaks nine more languages. German, Spanish, French, Italian, Japanese, Korean, Dutch, Brazilian Portuguese and Simplified Chinese, throughout: the film notes, the introduction, every button and the permission prompts. ### 1.0.1 — 2026-08-27 FRMT now runs on iPhones with iOS 17.2 and later, so it works on a great many more phones than before. Nothing else has changed. ### 1.0 — 2026-08-26 No release notes. ## More apps by Levi Foster - [MODUL8 - Glitch Art Effects](https://appshunter.io/ios/app/modul8-glitch-art-effects/id6755617539) - [Harmony Palette](https://appshunter.io/ios/app/harmony-palette/id6757116756) All apps by Levi Foster: https://appshunter.io/developer/1854976064 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
