Disclosure up front: I make Shiny, which appears in this list. I've tried to write this the way I'd want it written if I were the buyer: honest about what each tool actually does well, and honest about where the competition wins.
Why Memory Clean feels less useful on Apple Silicon
Memory Clean (by FIPLAB) was designed in an Intel era when the relationship between RAM, swap, and free memory was fairly straightforward. You had a fixed amount of RAM. When it ran low, macOS paged memory out to a spinning disk or SSD. Clearing memory meant asking macOS to release memory it was holding "just in case," and this often produced a visible improvement.
Apple Silicon changes most of those assumptions. The key differences:
- Unified memory architecture. On M-series chips, the CPU and GPU share the same physical memory pool. What counts as "free" RAM depends on who's asking. A number that looks alarming in a third-party monitor may be perfectly healthy because the GPU is using it and will release it the moment the CPU needs it.
- Memory compression is more aggressive. macOS compresses inactive memory before it ever touches swap. A compressed memory block counts as "used" in most monitors but is effectively available. Apps like Memory Clean can show a lower free-memory figure than reflects reality.
- Swap is fast, swap is NVMe. On Intel machines with spinning disks, swap meant a severe performance penalty. On Apple Silicon with fast NVMe storage, swap is far less catastrophic. The urgency that made memory cleaners feel necessary is reduced.
None of this means Memory Clean breaks your Mac. It means the numbers it shows may not mean what you think they mean, and the cleaning action may produce less improvement than it appears to. On M1 and later, even sudo purge in Terminal has limited effect for the same architectural reasons.

If you want to monitor: Stats (free, open source) and iStat Menus (paid, full)
Some people open Memory Clean not to clean anything, but just to see what their RAM usage looks like. If that's your habit, a pure monitor is a better fit than a cleaner.
Stats
Free, open sourceWhat it does: Stats is an open-source menu-bar system monitor covering CPU, RAM, disk, network, battery, and sensors. It shows real-time usage in a compact, configurable bar in your menu bar. No account, no subscription, no telemetry.
Apple Silicon aware: Stats is actively maintained and understands unified memory. Its RAM module shows memory pressure rather than just a raw free/used split, which is a more honest picture of how your Mac is actually doing.
Honest limit: It monitors. It does not clear memory. If you want a button to press when things feel slow, Stats is not the tool.
Best free option if all you want is to watch what's happening. Open source means anyone can inspect what it's doing with your data.
iStat Menus
$11.99 once (or SetApp)What it does: iStat Menus is the most comprehensive system monitor on Mac. CPU, GPU, RAM, disk, network, temperature sensors, fan speeds, battery cycles, and more. It has been around for over a decade and is genuinely polished. The RAM module shows memory pressure, app-level breakdown, and swap usage in detail.
Apple Silicon aware: iStat Menus has been updated for M-series Macs and understands the unified memory model. If you want the deepest possible picture of what your Mac's memory is doing, this is it.
Honest limit: Like Stats, it monitors. The depth of information can also be overwhelming. If you glance at it and feel more anxious rather than more informed, that's a real problem, not a trivial one.
Best paid option if you want comprehensive monitoring across all Mac subsystems, not just RAM.
If you want to act: Shiny ($4.99 once, three Macs, no telemetry)
Monitoring tells you the situation. Acting changes it. If what you want from Memory Clean is a button to press when your Mac feels slow, the relevant category is a memory cleaner, not a monitor.
Shiny
$4.99 onceWhat it does: Shiny is a menu-bar memory cleaner built specifically for modern macOS. One click frees memory. It shows you how much it freed before and after. It covers up to three Macs on a single purchase, has no subscription, and collects no telemetry.
Apple Silicon aware: Shiny uses the memory management APIs that work correctly on M-series chips, rather than relying on older approaches that produce misleading results. It also shows memory pressure (the metric Apple considers meaningful) rather than just a raw free-memory number.
Honest limit: Shiny is not a monitor. It does not show real-time graphs, sensor readings, or per-app breakdowns. If you want to watch your RAM all day, pair it with Stats. If you just want a button to press, Shiny is the tool. I am the developer, so factor that in.
The focused replacement for Memory Clean's cleaning function, built for Apple Silicon at a one-time price. See the full comparison with Memory Clean 3 for a detailed breakdown.
If you want both: Memory Diag (paid, focused), App Tamer (paid, slightly different angle)
Some people want a single app that both shows them what's happening and lets them do something about it. Two options are worth considering here.
Memory Diag
Paid (App Store)What it does: Memory Diag combines a real-time RAM gauge in your menu bar with a one-click clean button, in a tightly focused app. No disk scanning, no uninstalling, no antivirus. Just memory: watch it, then clear it when needed.
Honest assessment: Memory Diag is the closest functional replacement for Memory Clean in terms of combining monitoring and cleaning in one small app. The interface is clean and not overwhelming. It's available on the Mac App Store, which gives you some confidence around sandboxing and review.
Honest limit: It is not as actively developed as some alternatives. Check the App Store listing for the last update date before buying.
Closest like-for-like replacement for Memory Clean's combined monitor-and-act workflow in a focused package.
App Tamer
$14.99 onceWhat it does: App Tamer takes a different angle to memory management. Rather than waiting for memory to run low and then clearing it, it throttles background apps (browsers, Electron apps, video players paused in the background) that are quietly consuming CPU and RAM while you're not actively using them. The result is that memory pressure stays lower without you needing to take any action.
Apple Silicon aware: This approach works well on Apple Silicon because it works with macOS's memory management rather than against it. Less memory consumed by background processes means more headroom for active work, with no reliance on purge-style operations.
Honest limit: App Tamer is not a one-click cleaner and it costs more than the other options here. It is a system-level automation that runs quietly. Some people find this reassuring; others find it unsettling. It also does some monitoring, but its primary value is prevention, not visibility.
Best choice if your Mac's memory pressure is driven by background processes you forget to quit. Prevention rather than reaction.
The honest "should you replace it?" verdict
It depends on your workflow. Here is the honest breakdown:
If you use Memory Clean mainly to check your RAM: switch to Stats (free) or iStat Menus (paid). Both give you more accurate information on Apple Silicon than Memory Clean does, without any cleaning action you may not need.
If you use Memory Clean mainly for the clean button: try Shiny or Memory Diag. Both are built for modern macOS and give you a more accurate read on whether cleaning actually helped. On Apple Silicon, the improvement from clearing memory is real but more modest than on Intel. You will still feel it on genuinely memory-pressured workloads.
If you use it for both: Memory Diag is the closest like-for-like replacement. App Tamer is worth considering if you want a different philosophy: prevention over reaction.
If your Mac feels fine: you may not need to replace Memory Clean at all. The question worth asking is whether it's actually making a difference in your day-to-day work. On Apple Silicon with typical workloads (browser, email, light editing), macOS manages memory well without intervention. The tools above are genuinely useful for heavy workloads: video editing, running virtual machines, many browser tabs open simultaneously.
