Nimu Cam gives you the controls a real camera gives you, ISO, shutter speed and focus, and 29 filters built from the maths behind film stocks and magazine grades. You see the look in the viewfinder before you press the shutter.
AUTO and MANUAL sit side by side at the top of the screen, so you can switch mid shoot without hunting through menus. In automatic, the app still shows you what the iPhone chose, which is the fastest way to learn what a camera is really doing.
From 1/8000 to a full second, in the third stops a real camera uses. Freeze a runway walk, or let a night bus smear across the frame.
Set sensitivity yourself and keep it there, so a whole series matches instead of drifting frame to frame.
Tap to focus, or take the focus ring yourself and lock a distance so it stops hunting between shots.
In manual, a meter across the top shows how far your exposure sits from the reading, the way it does in a viewfinder.
An iPhone lens has a fixed aperture, so no app can really change it. The dial is marked SIMULATED: it recreates the exposure f/8 would give you, and it says so.
Ultra wide, wide and telephoto, with the zoom buttons where your thumb already expects them.
Each look is a colour grade plus the physical side of film: grain, vignetting, halation, light leaks, dust, scratches. The squares below are being graded in your browser right now, by the same code the app runs on the phone.
Open any picture from your library, try every filter on it with live previews, set how strong it should be, and hold the screen to compare with the original. Saving always writes a new photo, so the original is never touched.
An intensity slider takes any look from a whisper to the full thing.
Press and hold to see the original underneath, the way you would flick between two prints.
Your original stays exactly as it was. Every save is a new picture.
The camera, manual mode, the Darkroom and all 29 filters are free, with no trial and no countdown. The only thing the paid version changes is the file you save.

No subscription, no account, no ads, and nothing is collected about you either way.
Nimu Cam has no accounts, no analytics and no servers of its own. Filters run on the phone's own chip, which is why the app works in airplane mode. The only time a picture leaves is when you share it yourself.
Nothing to sign up for, nothing to sign in to.
Every filter is computed on the device, including the ones on this page.
No analytics in the app, and no cookies on this site.
No, and neither can anything else on an iPhone: the lens is fixed. The dial recreates the exposure change and is labelled as simulated.
Not yet. Photos are saved as high quality JPEG with their original EXIF, including the ISO and shutter you chose.
Any iPhone running iOS 17 or later. It runs on iPad too, with a layout made for the bigger screen.
They keep it. Open them again in the Darkroom after buying Pro and save a clean copy.
Free to download, free to shoot with, and the filters are yours to keep whether you ever pay or not.
