Also known as: Disk Reviewer: Clean Up Space
Active · Website · Store listing
Freemium sandboxed macOS cleaner from Texas studio Apis Systems LLC, Mac App Store only, built around a review-first constraint: every scan ends in an unticked file list and the only removal path is FileManager.trashItem to the Trash (photos go through PhotoKit to Recently Deleted). Scans caches/logs, uninstalls apps with leftovers, groups similar photos, lists large files, and a Developer Junk section covers Xcode DerivedData/simulators plus npm, Gradle, Dart and CocoaPods caches and Android emulator images; a background agent keeps a reclaimable-space figure in the menu bar. Pro is $4.99/year for Large Files and Developer Junk only. Marketing is unusually honest: the launch post concedes CleanMyMac covers more and DaisyDisk visualizes better, discloses opt-out anonymous counters, and explains that Duplicate Files is written but withheld over memory use.
Mechanical checks derived from the fields above. Each row is one fact; "not yet checked" means exactly that, not a failure. There is no composite score; read them together.

Sep 16, 2026 r/macapps — Disk Reviewer: a Mac cleaner that shows you every file and never deletes anything itself by u/that_fox2309removed
First promo attempt, five weeks after the App Store release. AutoModerator removed it (account needed a verified email and 10 comment karma); selftext unrecoverable ('[removed]'). Only comments are AutoModerator and the app-store-review bot summary.
Oct 29, 2026 r/macapps — Disk Reviewer: a Mac cleaner that shows you every file and can only move things to the Trash by u/that_fox2309
'Subscription' flair, v.redd.it demo video attached. Long-form post that reads like a design doc: honest competitor comparison, sandbox trade-off disclosure, telemetry disclosure, and a changelog narrative for 1.4.2 (menu-bar reclaimable figure, Large Files walker vs Spotlight missing 26 GB in *.noindex folders). Comments are substantive Q&A; he answers implementation questions (PhotoKit, package-cache safety) and builds a requested feature (custom Developer Junk folders) mid-thread.
I never trusted cleaners that decide for me. Every one I tried wanted the same thing: press a button, watch a number go up, hope it knew what it was doing. Twice I lost something I wanted back. — Problem statement
Every scan ends in a list with sizes and paths, you tick what goes, and the only operation the app can perform is moving files to the Trash. It calls FileManager.trashItem and nothing else, so anything it touches is sitting in the Finder until you empty it. — Trust signal
package caches are not the same kind of safe as DerivedData. DerivedData comes back from a local rebuild; a cleared npm or Gradle cache comes back over the network, which is a bad surprise on a plane. — Problem statement
It is sandboxed and Mac App Store only, so the system level junk unsandboxed cleaners reach is out of scope. That was a deliberate trade for being able to say it cannot do anything behind your back. — Trust signal
Nothing about your files leaves your Mac. There are anonymous counters for which features get opened, and a switch in Settings to turn them off. — Trust signal
I am the developer, happy to answer anything. — Engagement hook
