What tools and features does OneMacApp include?
Updated
OneMacApp bundles 39 native Mac tools for video, audio, images, PDFs, and on-device AI into a single app. It's aimed at people who regularly convert, compress, or edit media and documents and would rather use one local app than a scatter of websites and utilities. It requires macOS 26 or later, and the site lists it as a one-time $29 purchase.

What this means in practice
The tool set covers the common "I just need to…" tasks: shrink a video before sending it, pull audio out of a recording, convert a HEIC photo, remove a background, merge signed PDFs, or transcribe a meeting. Because the app runs on-device, files stay on your Mac rather than being uploaded to a converter site.
Two things to check before buying: your Mac must be running macOS 26 or later, and the $29 is described as a one-time purchase rather than a subscription. If you only occasionally need one of these functions, a single-purpose free tool may be enough; OneMacApp makes more sense if you'd use several of the 39 tools regularly and prefer keeping files local.
