Best photo editors for iPhone Duo

Darkroom and Halide Mark III are the photo editors here whose developers say they've been updated for iPhone Duo, as of Nov 7, 2026. The Lightroom, Photomator, Snapseed and VSCO listings don't mention iPhone Duo at all, and Apple's own Photos app is the free place to start.

This guide covers editing apps only. For what the 48 MP main and ultrawide cameras capture, see the camera reviews roundup, and for retouching with Apple Pencil (USB-C), see the best drawing and Pencil apps. Prices below are from each App Store listing as of Nov 7, 2026.

What to check before you pay

The App Store labels apps built with the iOS 27.1 SDK or later as Made for iPhone Duo, and those apps fill the whole inner display, MacRumors reported. Apps built with the iOS 26 SDK or earlier still run, but centered on the 7.6-inch inner display with empty space on each side.

That matters for an editor, where the photo is the whole point. Macworld's Jason Cross found older apps run in a small window with "huge black bars around it," in Macworld's iPhone Duo review.

Split View helps either way. Two apps share the inner display in a fixed 50/50 split, per MacRumors' Split View explainer, and Apple's iPhone Duo page shows browsing the Photos library on one side while dragging a picture into Mail on the other. More on that in the Split View guide and drag and drop between apps.

Apple Photos

Photos is Apple's built-in editor, so there's nothing to buy. Apple's iPhone Duo page also lists Apple Intelligence photo editing tools: Spatial Reframing to reframe a shot after it's taken, an Extend tool to expand photos, an enhanced Clean Up tool for larger objects, and Photographic Styles with texture and grain controls. A footnote on Apple's spec page says these intelligent photo editing tools are subject to daily usage limits.

The limitation: Apple says Clean Up is available in beta, and Apple hasn't described a Duo-specific editing layout for Photos beyond the Split View example. Photos also wasn't among the apps in Apple's Oct 22 newsroom roundup of iPhone Duo apps, which names no photo editors.

Darkroom

Darkroom is the clearest Duo pick. Bergen Co.'s App Store listing says version 7.5 added iPhone Duo support with an optimized, responsive interface, and the notes add that the interface is "fully responsive to every iPhone Duo pose." The Darkroom website says the app is optimized for iPhone Duo on day one, for all poses, alongside faster RAW rendering and 100MP RAW support.

Darkroom is free to download, with a $9.99 monthly or $39.99 yearly subscription and a $99.99 Unlock Everything Forever purchase, as of Nov 7, 2026. It requires iOS 18.4 or later.

The limitation: Darkroom's website says Darkroom+ is required only when you export, so you can edit for free but need to pay to save edits out of the app. Neither page mentions Split View.

Halide Mark III

Halide Mark III is a camera first, with an editor built in. Lux Optics' App Store listing says version 3.3 adds support for iPhone Duo. Lux's Oct 26 post on Halide for Duo says that with the phone fully open, a second view shows your last photo, ready to favorite, share, delete or edit with one tap.

The editor is Photo Lab, with Quick Edit, Frame, Exposure, Film and Balance sections, per Lux's Halide Mark III page. It can also import RAW files from standalone cameras.

Halide is free to download, with in-app purchases listed at $9.99 and $19.99 and a $69.99 one-time purchase, as of Nov 7, 2026. It requires iOS 18.0 or later.

The limitation: Lux's Duo post is about shooting, and it doesn't describe how Photo Lab uses the inner display. Lux also calls RAW import from other cameras a beta feature that may crash.

Lightroom

Lightroom is Adobe's mobile editor. Adobe's App Store listing shows version 12.0 adding a glow effect, an AI Assistant in Early Access and faster Blemish Removal. It's free to download with Premium plans sold in the app, and it requires iOS 18.0 or later.

The limitation: the listing doesn't mention iPhone Duo, and Adobe's Lightroom mobile release notes, last updated Sept 29 and ending at version 11.6, don't mention it either. Check for the Made for iPhone Duo label before you pay for Premium.

Photomator (and Pixelmator)

Photomator is now listed with Apple as its developer, per its App Store listing. It's free to download with subscription and lifetime purchases, and it requires iOS 17.0 or later.

The limitation: the latest version, 3.4.15, is dated Aug 27, so it predates the Duo launch, and the listing doesn't mention iPhone Duo. The older Pixelmator app for iPhone is no longer being updated, according to Apple's statement as reported by appgefahren, so skip it for the Duo.

Snapseed

Snapseed is the free pick. Google's App Store listing says there are no subscriptions, purchases, ads or watermarks. Version 4.2.0 added Motion Blur, a depth-based Lens Blur and a Tone Color tool with color wheels. It requires iOS 17.0 or later.

The limitation: the listing doesn't mention iPhone Duo, so it may not fill the inner display.

VSCO

VSCO is a preset-focused photo and video editor. Visual Supply Company's App Store listing shows VSCO Plus at $9.99 a month or $39.99 a year and VSCO Pro at $14.99 a month or $69.99 a year, as of Nov 7, 2026. It requires iOS 15.0 or later.

The limitation: the listing doesn't mention iPhone Duo, and the latest update lists only crash and bug fixes.

Which one should you get?

For a Duo-optimized editor today, start with Darkroom, and budget for Darkroom+ if you export often. If you shoot RAW in a third-party camera app anyway, Halide Mark III puts capture and Photo Lab in one Duo-aware app.

For free edits, use Photos, with Snapseed as a no-subscription backup. Lightroom subscribers should keep using it, but on paper Lightroom, Photomator and VSCO aren't Duo-specific yet, so the big screen may go partly unused.
