Closed-source macOS all-in-one cleaner from solo Turkish indie developer Lokman Şahin, launched on r/macapps 2026-11-01 at a $9 early-bird one-time price. Seven modules in one SwiftUI window: junk scan (caches, logs, Xcode build data, unavailable simulators, Trash), app uninstaller with leftovers and update checks, SHA-256 duplicate and similar-image finder, bubble Space Map, adware and browser-privacy scans, login/background-item and maintenance tools, Time Machine local-snapshot removal, plus a menu-bar monitor. Review-first cleaning: every item listed with path and size, nothing preselected, Trash-first removal, dry-run mode, ignore list. macOS 14 Sonoma+, Developer ID-signed dmg, license via Polar. Site runs a 100%-cashback offer for a Reddit or X post that reaches 2,000 views.
Lokman Şahin, solo developer; real name, LinkedIn and personal Gmail published in the launch post. Second shipped product: Lessmoke, a freemium iOS quit-smoking app on the App Store since Sep 2025.

CleanMacster.dmg (36.9 MB, HTTP last-modified 2026-10-21, served from cleanmacster.app/download) embeds a 'Developer ID Application: Lokman sahin (9JH22BL8HR)' signature.
Privacy policy (dated 2026-10-21): all scanning and SHA-256 duplicate matching run locally; the app's stated network use is Apple's public App Store lookup for installed-app updates, plus license/update checks with a 30-day offline grace after activation.
Only a general hello@cleanmacster.app contact is published; no dedicated security channel or disclosure policy.
Site FAQ: admin password is asked only for tasks marked as needing it; Full Disk Access requested to reach protected folders such as Mail and Safari data.
Launch post: 'Licensing and updates connect online' - the update mechanism is not further described.
Same developer name as the CleanMacster signing cert; quanre recommended it in r/stopsmoking comments (Dec 2025). Freemium subscriptions; not catalog-eligible.
Launch post: 'AppCleaner focuses on removing apps and their related files; DaisyDisk focuses on visual disk exploration. CleanMacster's difference is bringing those workflows together with duplicate detection, cleanup categories and system monitoring.'
Unprompted in-thread comparisons by commenters; the author conceded 'There's overlap with Mole's features, and I'm not claiming CleanMacster is inherently safer or cleans more.'
Unrelated near-same-name: a free Mac App Store cleaner listed since July 2020 by 'Any Case Solutions, OOO'. No shared developer, domain or signing identity - one-letter echo of the same CleanMyMac-derived naming lane.
Unrelated near-same-name: Cheetah Mobile's Windows junk cleaner, live since ~2017 (the Android flagship was pulled in Google's Feb 2020 Play purge). Different developer, platform and era.
Research notes
Launch-scale breadth: seven modules plus ~17 standalone tools claimed at launch - CleanMyMac-suite scope (uninstaller, duplicates, space map, adware, privacy, login items, tune-up tasks, menu-bar monitor) from a solo developer shipping his first macOS app.
Pay-for-post incentives: the site refunds 100% of the purchase price to any buyer whose public Reddit post, comment, tweet or reply naming CleanMacster reaches 2,000 views, and a creator program pays $7 per sale through 30-day tracked links. Near-term social praise should be read as incentivized.
Safety design is the pitch: per-item review with paths and sizes before anything is removed, nothing preselected, Trash-first deletion, dry-run mode, ignore list, /System and key user folders off-limits, admin-requiring tasks marked and prompted. Site and post claims, unverified.
Real-name developer: the launch post opens 'I'm Lokman, the developer of CleanMacster' and closes with his full name, LinkedIn and a personal Gmail; the dmg signing cert reads 'Lokman sahin (9JH22BL8HR)'.
In-thread candor above the cohort norm: the author asked for criticism, conceded overlap with Mole ('I'm not claiming CleanMacster is inherently safer or cleans more') and wrote the AppCleaner/DaisyDisk comparison into the post itself.
Earliest promotion found and the account's first product post (archived 2026-11-02, 28 comments captured). Video post; the text self-describes the app, pricing and privacy posture, and signs off with the developer's name, LinkedIn and Gmail.
When a Mac runs low on storage, a single "you can free up X GB" number doesn't explain much. Is it an old installer, an app's support files or something you still need? CleanMacster shows individual items, paths and sizes so you can review the list before removing anything. — Problem statement
AppCleaner focuses on removing apps and their related files; DaisyDisk focuses on visual disk exploration. CleanMacster's difference is bringing those workflows together with duplicate detection, cleanup categories and system monitoring. — Virtue
File scans and duplicate matching happen locally. Licensing and updates connect online; an activated license supports up to 30 days offline after verification. — Trust signal
