Nitro

Nitro is a photo editor and manager for photographers, available on macOS and iOS. It works with Apple Photos and iCloud Photos, as well as files in Finder, Files.app, and external storage. Editing tools include 16 precision adjustments, AI subject and background masks, gradients, brushes, cloning, and spot removal. Nitro supports Apple-supported RAW formats, DNG, iPhone ProRAW, compressed Fujifilm, Nikon HE and HE*, GoPro RAW, and additional camera formats; its RAW controls use Apple’s RAW engine. It reads and writes XMP sidecars for workflows across apps and exports JPEG, TIFF, HEIF, and PNG. The macOS app includes ExifTool integration, metadata search, and GPS maps. It can compare up to 16 images with synchronized pan and zoom; the iPad app can compare up to four. Nitro includes a Photos editing extension, and Apple Photos changes can sync through iCloud Photos. A seven-day trial is available without subscription signup. A lifetime purchase costs $99.99 one-time and includes macOS, iOS, and future updates; VAT and other taxes are excluded. Monthly and annual subscriptions are also offered, with App Store pricing details.

Nitro combines photo management, editing, metadata tools, and image comparison for macOS and iOS. Check its platform requirements and NAS compatibility, and note that the lifetime price is $99.99 one-time before VAT and other taxes.

Nitro suits photographers who want RAW editing, image comparison, and catalog workflows across Apple devices. It may also fit users working with Apple Photos, iCloud Photos, or XMP sidecars.

Overview

Nitro brings photo cataloging, editing, metadata tools, and image comparison to Apple devices. It is best suited to photographers who work across Apple Photos and files in Finder or external storage and want detailed RAW and selection tools. Its breadth is appealing, but its Apple-only requirements and a NAS compatibility limit narrow the fit.

Key features

Nitro can work with Apple Photos and iCloud Photos, as well as files in Finder, Files.app, and external storage. That flexibility suits photographers who divide their libraries between a managed photo library and folders; catalog workflow support keeps it relevant beyond one-off edits.

Editing combines 16 precision adjustments with AI subject and background masks, gradients, brushes, cloning, spot removal, lens correction, and local adjustments. This gives photographers both global controls and targeted cleanup tools in one editor. Export options include JPEG, TIFF, HEIF, and PNG.

RAW support covers Apple-supported formats, DNG, iPhone ProRAW, compressed Fujifilm, Nikon HE and HE*, GoPro RAW, and additional camera formats. Its controls use Apple’s RAW engine, so it is a particularly natural fit for Apple-based workflows. XMP sidecar reading and writing helps move metadata and edit workflow between compatible apps.

The macOS app adds ExifTool integration, metadata search, GPS maps, and comparison of up to 16 images with synchronized pan and zoom. On iPad, comparison supports up to four images. Those features make Nitro more than a basic editor for photographers sorting similar frames, though the larger comparison capacity is reserved for Mac.

A Photos editing extension and iCloud Photos syncing let edits fit into Apple’s photo workflow. The tradeoff is platform dependence: the supported platforms are macOS and iOS, and UGreen NAS is not compatible.

Pricing

Nitro offers a seven-day trial with no subscription signup required, a useful way to assess the workflow before paying.

The Lifetime purchase costs $99.99 one-time purchase. It includes macOS, iOS, and future updates, with VAT and other taxes excluded. For photographers committed to Nitro across Apple devices, the one-time payment avoids recurring billing and covers both platforms. A subscription may suit someone who prefers a shorter commitment, but its cost depends on the App Store offer.

Nitro also has a free plan, but its capabilities and limits are not described. That makes it difficult to judge whether it can serve as a lasting free option; the seven-day trial is the clearly defined route for evaluating the paid product.

Platforms

Nitro supports macOS and iOS, with macOS Ventura or later and iOS 16 or later required. The maker also describes an extension, including a Photos editing extension. There is no Android or Windows version in the supported platform set, and UGreen NAS is incompatible.

Who it's for

Nitro is a strong candidate for enthusiast and professional photographers who use Apple devices, work with multiple RAW formats, and want editing, metadata search, and synchronized side-by-side comparison in one workflow. Its support for both Photos libraries and ordinary files is useful for mixed catalog habits.

It is a poor fit for photographers who need Windows or Android support, rely on UGreen NAS, or want a clearly priced subscription before starting a trial. Buyers who need only basic RAW processing may also find Nitro’s broader management and comparison toolkit unnecessary.

Pros and cons

Pros

• Wide RAW coverage: support for Apple-supported RAW, DNG, iPhone ProRAW, compressed Fujifilm, Nikon HE/HE*, and GoPro RAW serves varied camera workflows.
• Useful selection tools: synchronized comparison supports up to 16 images on Mac and four on iPad, helping narrow similar shots.
• Flexible photo access: work with Apple Photos and iCloud Photos or with files and external storage.
• One-time cross-platform license: the $99.99 purchase covers macOS, iOS, and future updates.

Cons

• Apple-only requirements: macOS Ventura or later and iOS 16 or later rule out older systems and non-Apple platforms.
• UGreen NAS incompatibility: photographers relying on that storage setup will need another workflow.
• Free-plan scope is unclear: without stated capabilities or caps, it is not a dependable basis for choosing Nitro as a free editor.

Alternatives

Compare RAW photo processing software if you want to survey more options before settling on Nitro.

Photomator is worth considering for Apple users who want a $7.99 a month subscription covering Mac, iPad, iPhone, and Apple Vision Pro, rather than Nitro’s one-time cross-platform purchase.

Adobe Lightroom is the alternative to consider when you need Android, Windows, or web access alongside Apple platforms; it is freemium and offers a free trial.

Capture One may suit photographers seeking desktop RAW conversion, tethering, and advanced desktop editing tools, with a free trial and no free plan.

ON1 Photo RAW is an option for photographers who need Windows or Android support in addition to Apple platforms and want to consider plans covering multiple computers.

Darkroom offers a free Starter tier for trying premium tools, though exporting requires Darkroom+; consider it if that trial-style access matters more than Nitro’s defined seven-day trial.

RAW Power is another Apple Photos and Finder/iCloud Photos option, with a Photos extension and a free trial.

Luminar Neo is an alternative if you need Windows or Android support as well as macOS and iOS.

ART is a free, open-source RAW image processing program for Linux, macOS, and Windows, a better direction if zero-cost access and desktop platform choice matter most.

Verdict

Choose Nitro if you are an Apple-based photographer who wants a single tool for photo management, detailed editing, metadata work, and comparing frames, especially across Mac and iPad. Its broad RAW support and $99.99 one-time license are compelling. Look elsewhere if you need Windows or Android, depend on UGreen NAS, or want subscription pricing clearly established before you commit.
