- Who is Klarity Disk for: Budget conscious Mac users who want a visually clean way to understand disk usage and are confident managing deleting files via the Finder.
- Who is Klarity Disk not for: Those who need seamless file deletion.
Visual disk analyzers sum up everything on your Mac and present that in a cohesive form. The best of these achieve this task and make something unwieldy that much more manageable. Klarity Disk, by developer Mukul Mehra, is a disk analyser that’s similar to DaisyDisk (see our review of DaisyDisk).
Klarity Disk offers disk visualization as well as other low-level features, such as CPU, GPU, and RAM monitoring. You can use it to scan your Mac to get details of the files that are taking up space and use Reveal in Finder to locate and delete them yourself, although there were some permissions issues relating to deleting applications at the time of this review. It’s only $6.99 from Klarity Disk or the Mac App Store, compared to $9.99 for DaisyDisk, which is a good price, but we’d recommend waiting for the permissions issues to be fixed.
Klarity Disk is easy to dive into and navigation is easy and elegant. The program feels like it’s dedicated to a few tasks and isn’t trying to be every Mac utility under the sun, which is appreciated.
Klarity Disk will give you a simple overview.
Foundry
There are six color themes to aid visual customisation so you can differentiate file groups and folders, scan file sizes, or understand the hierarchy at a glance. Choose from Klarity, Arctic, Ember, Verdant, Blush, and Ocean themes.
It’s simple to get a quick lay of the land with the Overview function, which shows how much RAM is being used, what your Mac’s remaining drive capacity is, the memory timeline, and the top processes currently occupying your CPU.

The Disk Analyzer mode makes it easy to scan large files, such as your Applications folder, and to see which giant applications are munching on your Mac’s available drive space.
Visualise your storage.

There’s an additional level of functionality beyond simply seeing what’s occurring on your Mac. Right-clicking or option-clicking on an application will bring up options such as seeing where the application is located via the Finder, copying the drive path, or sending the application to the trash.
Permissions bug undermines core functionality
Upon trying to remove applications by sending them to trash, Klarity informed me that I lacked permission to dispose of the item, despite having an admin-level account. The same error occurred with other applications, suggesting that some of the issues encountered were due to compatibility with the version of macOS Tahoe I was running. The update to macOS 26.4 did seem to fix some issues we had experienced with Klarity, but the permissions issue remained.
The developer makes some nice pledges in the application’s notes about no cloud services being used, no account needing to be created, and that no analytics or data collection is used, which is appreciated, but bug fixes are needed to address the application’s core functionality.

Should you buy Klarity Disk?
Klarity Disk looks appealing and offers a clean, beautiful approach to visualizing your Mac’s disk usage alongside its performance stats. This, along with a reasonable $6.99 price point, adds to its appeal, but there are bugs that need to be addressed in the current version (Klarity Disk 1.1) including persistent permissions errors.
