Workflow
Shoot in IIWII. Finish in masoc.
IIWII gets the look right when you press the shutter. masoc is where you take it further. Here is how the two fit together, which files to keep, and what stays private along the way.
Two apps, two jobs.
A camera that decides fast, an editor that lets you take your time.
A camera app should be quick: one look, one tap, a finished photo. An editor should be patient: masks, curves, a second look at a photo days later. Putting both into one app makes either slower. So IIWII and masoc split the job, and share what matters: the same 22 color tables, from Fujifilm-style looks like Classic Chrome and Classic Neg to Portra 400, Kodak Gold and CineStill 800T.
That means a look you shot in IIWII exists in masoc under the same name. You can shoot with it, and later apply it again to the raw file, at any strength, on top of a proper edit.

Keep the right files.
What IIWII saves, and what each file is for.
IIWII saves everything straight into your photo library, without creating albums. What lands there depends on two switches in Settings › Processing & Export:
| File | When | What it is for | Note |
|---|---|---|---|
| HEIC (or JPEG) | Always | The photo with its look. Ready to share. | Look is baked in |
| DNG | RAW+ on | Sensor data without a look, for editing. | Bayer RAW, or ProRAW on Pro models |
| TIFF, 16-bit | RAW as TIFF on | A flat, developed file for desktop grading. | Throwback is off in this mode |
A few details that help later:
- The DNG is its own photo in the library, not attached to the HEIC. Look for the RAW badge in Photos.
- The look name is written into the photo’s caption, so you always know what you shot with.
- The DNG and TIFF are saved without location. The HEIC carries it only if you allow GPS in IIWII.
Throwback first, masoc second.
Two ways to change your mind.
If you only want a different look, you may not need an editor at all. Throwback in IIWII, on iOS 17 and later, keeps an unfiltered copy of your recent photos inside the app. Swipe up in the gallery, pick another look, and IIWII saves it as a regular, reversible edit in Photos. Revert in Photos brings back the original.
When you want more than a new look, such as straightening, local adjustments, removing a distraction or a careful grade, that is masoc’s job. Start from the DNG. A HEIC already has its look baked in, and stacking a second look on top rarely ends well.
Finishing in masoc.
From the library to the finished photo, on the device.
- Import the DNG from Photos, Files, the share sheet or the clipboard.
- Pick the look you shot with under Looks › Profiles, and set its intensity.
- Edit: white balance in real Kelvin on RAW, curves, masks for sky, subject or background, and Smart Edit on devices with Apple Intelligence.
- Export. masoc never changes the original file.
masoc runs on iPhone, iPad and Mac with iOS 26, iPadOS 26 or macOS 26 or later, and needs a Mac with Apple silicon. Its AI tools run on the device, there is no account, and iCloud sync stays off until you turn it on. Then it uses your own private iCloud. It opens Apple ProRAW and the RAW files of Canon, Nikon, Sony, Fujifilm and other cameras as well, so the same workflow works with a real camera.
masoc is a free download with every tool and three free exports. Unlock masoc costs $3.99 a month, $24.99 a year or $69 once, with Family Sharing.

Private by design.
No step in this workflow uploads a photo.
- IIWII has no servers, no account and no analytics in the app. Photos go to your library and nowhere else.
- masoc edits on the device, including its AI masks, and syncs only through your own iCloud if you turn it on.
- Your files stay standard: HEIC, DNG and TIFF open in any app, so you are never locked in.
Questions and answers
Does masoc keep my IIWII look editable?
Not the look baked into a HEIC. masoc has the same 22 color tables, so you apply the look again to the DNG and keep full control. Inside IIWII, Throwback can swap the look of a recent photo.
Where does IIWII save the RAW file?
In your photo library, as its own photo next to the filtered one. In the Photos app you find it by its RAW badge.
Do I need iCloud for this workflow?
No. IIWII has no cloud at all, and iCloud sync in masoc is off until you turn it on. Then it uses your own private iCloud.
Where do I get masoc?
On the App Store for iPhone, iPad and Mac. Every tool is free to try, and masoc.app has the details.
Try it on your iPhone.
IIWII costs $2 once. No subscription, no account, no ads. Runs on iOS 15 and later.
