I make Shiny, so this comparison comes from a biased source. I've tried to write it the way I'd want it written if I were the buyer: honest about where CleanMyMac wins, honest about where Shiny does, and clear about who each tool is right for.

Where CleanMyMac wins
I want to start here because comparison posts that don't concede anything sound dishonest. CleanMyMac is a real, well-built product, and there are clear cases where it's the better tool.
Breadth. CleanMyMac is a Mac-maintenance suite. It cleans caches, finds large old files, uninstalls apps cleanly, scans for malware, and runs maintenance scripts, all in one interface. If you want one app that does everything, that's a real benefit.
Malware scanner. CleanMyMac includes a malware scanner with a friendly visual interface. macOS already has a built-in scanner (XProtect), but if you want a second opinion that surfaces things visually, CleanMyMac's is reasonable.
App uninstaller. CleanMyMac's uninstaller cleanly removes apps and their leftover preference files. (AppCleaner does this for free, but CleanMyMac integrates it nicely.)
Years of polish. CleanMyMac has been on the market since 2008. The interface is mature, the workflows are smooth, and the company is well-resourced. Shiny is a small operation; the polish is good but it is not 17 years of polish.
Where Shiny wins
Price. $4.99 once vs $40/year ongoing. Over five years that's $4.99 vs $200. If memory is the only feature you'd use, the price gap is enormous.
Focus. Shiny does one thing: free memory. Click the menu-bar button, it closes orphaned helper processes, releases inactive memory, pauses idle apps, shows you what it freed. There's no dashboard to navigate, no scan to run, no popup to dismiss. The whole experience is "click, done."
Zero telemetry. Shiny collects no analytics, no usage stats, no error reports, no anything. CleanMyMac defaults to anonymous usage stats (you can opt out, but it's on by default). If telemetry-zero matters to you, Shiny is the stricter choice.
No popups. Shiny doesn't tell you your Mac is at risk. It doesn't suggest scans. It doesn't run "Smart Care" reminders. It sits in the menu bar quietly until you click it.
One developer. Some people prefer indie software for the trust signal alone. If you do, Shiny qualifies. (If you don't care, that's also fine.)
Three-Mac coverage out of the box. One Shiny license covers up to three Macs that you personally use. CleanMyMac plans typically cover one Mac per license; family plans exist but cost more.
Who Shiny is for
You'll probably prefer Shiny if:
- You only want a memory cleaner, not a full Mac-maintenance suite.
- You prefer one-time payments over subscriptions.
- You don't want any analytics or usage tracking, ever.
- You find dashboards and notifications annoying. You want a single button.
- You like indie software, or just smaller, focused tools.
- You have multiple Macs and want one license to cover them.
- Your Mac is already mostly fine and you just want a quick way to clear memory pressure when it edges yellow.
Who CleanMyMac is for
You'll probably prefer CleanMyMac if:
- You want a single app that handles memory, malware, uninstalling, and disk visualisation.
- You'd rather pay one subscription than buy four single-purpose tools.
- You like a friendly, polished interface with a clear dashboard.
- You'll genuinely use four or more of CleanMyMac's features regularly.
- You don't mind the popups and Smart Care reminders, or you're happy to disable them.
- You want a mature, well-supported app from a 17-year-old company with phone support and a dedicated team.
Should you switch from CleanMyMac to Shiny?
Honest answer: only if you've audited which CleanMyMac features you actually use, and the answer is "mostly the memory one".
Open CleanMyMac and look at which sections you've clicked in the last six months. If it's mostly the memory cleaner, Shiny replaces it. If you're using malware scans, app uninstalls, and disk views, switching to Shiny means giving those up (or replacing them with single-purpose tools like Malwarebytes Free, AppCleaner, and DaisyDisk).
The honest middle path: keep CleanMyMac for the breadth, install Shiny for fast menu-bar memory clearing. They don't conflict. Many people end up using Shiny daily for the quick memory tap and CleanMyMac monthly for the deeper maintenance.
Bottom line
If you only need a memory cleaner: Shiny. $4.99 once, three Macs, no telemetry, no subscription. Done.
If you want a full Mac-maintenance suite: CleanMyMac. $40/year, one Mac, broad features, mature company.
If you want both: nothing stops you from running Shiny in the menu bar for fast memory clearing while keeping CleanMyMac for the deeper jobs.
Either way, you're not making a bad choice. Both apps are notarized, both are made by real companies, both do what they say. The decision is mostly about how much breadth you actually need and how much you want to pay over time.
