Mac disk space analyzer See your disk. Clearly.
Klarity draws your Mac’s storage as a map: every folder sized by the space it takes and coloured by how long it’s sat untouched. The big, forgotten stuff can’t hide.

See it.
Every folder drawn to scale and coloured by age, so you know what’s big and what’s forgotten at a glance.
Clear it safely.
Klarity only ever moves things to the Trash. Folders of 1 GB or more need a slide to confirm, and system folders stay off-limits.
Keep it private.
No network connections, no account, no analytics. What Klarity learns about your disk stays on your Mac.
Features
Everything you need to understand your storage.
Big and forgotten
See what you haven’t touched in years.
Colour by age turns the map into a to-do list: red for three years and more, blue for this month. Hover any tile for its size and age; the inspector shows when it last changed.

New in 1.3.1
Finally, see System Data.
Klarity now opens hidden folders like Library, where caches, Xcode leftovers and old iPhone backups pile up: the space Storage settings files under a grey “System Data” bar.

Large Files
Find the big files you forgot.
Switch to Large Files for a list sorted by size, with how long it’s been since each file changed. Pick the ones you don’t need and move them to the Trash.

Safe by design
Clear space without the risk.
Everything goes to the Trash, never straight to deletion. A folder of 1 GB or more needs a deliberate slide, and Klarity refuses to touch what your Mac depends on, like Library or Keychains.

Made for macOS.
Native SwiftUI, light by default and dark in one click, with a menu-bar readout that keeps memory and disk use in sight.
Why it’s different
Not all visualizations are created equal.
Most disk analyzers use sunburst charts. Research shows rectangular layouts are measurably better at comparing file sizes, so Klarity gives you both a treemap and an icicle view.
Treemap
Rectangles sized by file size. Your eye compares areas instantly. No angle math, no distortion at different depths.
Icicle
Horizontal bars aligned on the same baseline. Compare folders at the same level by looking at bar width. Hierarchy is depth, not angle.
Sunburst (others)
Encodes size as arc angle. Outer rings look visually larger even when they’re not. Brendan Gregg calls them “the new pie chart.”
Compare
Built different from the ground up.
Two visualization modes, a built-in RAM monitor, delete safety guards, and zero data collection. No other disk analyzer offers this combination.

Reviews
What people say.
Macworld reviewed Klarity Disk in April and rated it 4 out of 5, praising the settings, the RAM and CPU tools and the one-time price. It also found a real bug; Klarity 1.3 was rebuilt around fixing it.
“Finally a disk analyzer that actually looks good. The treemap view is so much more intuitive than DaisyDisk’s sunburst.”
“Freed up 47GB in 10 minutes. The icicle view made it crystal clear where all my Xcode caches were hiding.”
“Love that it’s a one-time purchase. The RAM monitor in the menu bar is a bonus I didn’t expect. Replaced two apps with one.”
What’s new
New in Klarity 1.3.1.
- A redesigned Klarity: a new light look (dark is one click away in Settings), a Finder-style sidebar with your locations, and an inspector that shows what’s inside the folder you pick.
- Klarity now scans hidden folders such as your Library, so the space macOS calls “System Data” finally shows up. A new Library shortcut takes you straight there.
- Photos libraries, video projects and virtual machines now count toward their folder’s size everywhere, not just when you open them.
- New option in Settings › Appearance: colour folders by the age of most of their space, so big folders full of old files stand out even if one file changed today.
- Sizes now show the space files actually take on your disk, so iCloud files that aren’t downloaded no longer count.
- Klarity won’t move folders your Mac depends on, such as Library or Keychains, to the Trash, and it asks twice before trashing app data, iCloud folders or files inside photo and video libraries.
- Clearer permission prompts: each one explains what Klarity measures.
