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. Klarity gives you both treemap and icicle views.

◫ Klarity

Treemap

Rectangles sized by file size. Your eye compares areas instantly. No angle math, no distortion at different depths.

▤ Klarity

Icicle / Flame Graph

Horizontal bars aligned on the same baseline. Compare folders at the same level by looking at bar width. Hierarchy is depth, not angle.

◎ Others

Sunburst

Encodes size as arc angle. Outer rings look visually larger even when they're not. Brendan Gregg calls them "the new pie chart."

Reviews

Loved by beta testers.

★★★★★

"Finally a disk analyzer that actually looks good. The treemap view is so much more intuitive than DaisyDisk's sunburst."

Beta Tester
iOS Developer
★★★★★

"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

Version 1.3 — one grant,
every volume.

Klarity now asks for disk access once, explains why, and remembers it. Scanning and deleting work the same everywhere — including Macintosh HD.

New
🔑

Move to Trash Works Everywhere

One grant, remembered per volume

Klarity asks for access to your disk once, explains why it needs it, and remembers the grant per volume. No more deletes that fail outside your home folder.

New
💽

Scan Macintosh HD

One click, accurate totals

Scan your whole startup disk with one click. The scanner no longer double-counts the APFS data volume, so your startup disk is counted once.

Improved
🛡

Honest Admin Message

No more mystery failures

Items macOS protects now say "Finder needs an admin password" instead of failing quietly, with a Reveal in Finder button so you can finish the job yourself.

Improved
📂

Ask, Don't Show Empty

Folders you haven't granted yet

Scanning a folder Klarity can't read yet — like Downloads before any grant — now asks for access instead of showing an empty result that looks like a bug.

Improved
⏱

Preferences That Stick

Refresh Interval and menu bar

Refresh Interval now actually takes effect and is remembered across launches, and your menu bar preferences are remembered too.

Improved
#️⃣

Version and Build

Easier bug reports

The build number now shows after the version, e.g. 1.3 (1300), so it's clear exactly which build you're running when something needs reporting.
