Lists of "best apps to clean memory" often repeat the same names without explaining what each one does differently — and many of them even mention programs that are no longer available in the official store. This selection is something else: five tools available today on the Play Store, with the specific function of each one and what it doesn't do.
Before the list, a reminder that changes the choice: all these tools act on storage. None of these methods speed up your phone by clearing RAM — this point is explained at the end of the text.
1. Files by Google — the most suitable for most people.
It's a file manager and cleaning assistant all in one. The home screen suggests large files, duplicate images, old screenshots, media received in conversations, and unused apps. It's free, lightweight, published by Google itself, and doesn't rely on ads, making it the default choice, especially on phones with limited memory.
What he doesn't do: It doesn't find remnants left by uninstalled applications with the same depth as specialized tools. View on the Play Store.
2. SD Maid 2/SE — the most transparent
This is the option for those who like to know exactly what will be deleted. It locates orphaned folders from already removed applications, duplicate files, and leftover files scattered throughout the storage, and presents the complete list before taking action. The interface is more technical than its competitors, and some of the advanced features are only available in the paid version.
What he doesn't do: It's not the most user-friendly tool for someone who just wants to press a button. View on the Play Store. The previous version, the SD Maid 1, It's still available and it's lighter.
3. CCleaner — the most comprehensive in reports
It offers detailed storage analysis, lists apps by size and usage, performs batch cache cleaning, and provides a dashboard with device information. The free version is ad-supported, while the paid version removes ads and enables scheduling.
What he doesn't do: The memory optimization button it displays does not deliver any performance gain, for the reason explained below. View on the Play Store.
4. AVG Cleaner — good for duplicate photos
Its most interesting function is image analysis: it groups similar, blurry, or low-quality photos and suggests which ones to discard, keeping the best from each series. For those who take many photos of the same scene, this saves a lot of space. It also cleans the cache and lists unused applications.
What he doesn't do: This does not replace backups — review the suggestions before confirming, as the quality assessment is automatic. View on the Play Store.
5. Avast Cleanup — application hibernation
In addition to the usual cleaning of cache and large files, it offers a feature to suspend applications that run unnecessarily in the background. This is useful on devices with many installed programs, although Android already does something similar automatically with apps that have been abandoned for months.
What he doesn't do: The free version limits some features and displays ads frequently. View on the Play Store.
The button that everyone has and no one should use.
The five apps above display, somewhere, a RAM meter with a "free up" button. Ignore it. On current Android systems, the system keeps recently used apps loaded because idle memory doesn't speed anything up, and it automatically closes old processes when it needs space. Forcing everything to close forces the device to reload each program afterward, wasting battery and even delaying messaging notifications.
It's also worth knowing that this category has a history: cleaning apps with hundreds of millions of installations have been removed from the official store for abusive advertising practices. Therefore, the list above is limited to what is available and maintained by identifiable developers. Before installing any alternative, check who published it and their permission list. accessibility service It is requested that there is no justification for this category, because it allows reading the screen and simulating touches.
How to test any of them in five minutes.
Before trusting the number displayed on the screen, it's worth doing a test that anyone can do to separate the tool from the theatrical:
- Note the free space. on the system storage screen — not on the application screen.
- Rotate the cleaning And note how much he claims to have released.
- Return to the system screen. and compare the actual free space.
- Repeat the cleaning process immediately. If it finds another mountain of "junk" seconds later, it was counting a temporary file that the system recreates on its own.
- Restart and observe. If the feeling of speed appears the same without running the application, then the credit goes to restarting.
In most cases, the space actually freed up is a fraction of what was advertised — and it's close to what the native tool frees up, without advertising and without broad permissions.
What to look for on the store's listing before installing.
- Permissions granted. A cleaner that asks for SMS, contacts, microphone, camera, or precise location is requesting things that the function doesn't use.
- Data security section, where the developer declares what data they collect and whether they share it with third parties for advertising.
- Developer's name And what else did he publish? A portfolio of dozens of generic utilities is standard advertising.
- Date of last update. An application that has been dormant for years often breaks in a new version of the system.
- One-star and three-star reviews, where unexpected charges, excessive advertising, and cleaning that removed something inappropriate appear.
- Installer size. A simple utility, typically hundreds of megabytes in size, usually contains an advertising library.
And the criterion that discards them immediately, without discussion: Accessibility service request or device administrator request. No cleaner needs to read your screen or make uninstallation difficult.
Why do popular apps in this category leave the store?
This happens frequently and is useful information for the reader because it explains the behavior of the sector. The recurring reasons are:
- Advertising outside the app — Full-screen ads appearing when the user is in another app or on the home screen, a practice prohibited by the store's policies.
- Data collection incompatible with the stated function.
- Misleading claim in the description., such as increasing memory or speeding up the processor.
- False emergency notification, simulating a system alert to generate ringtones.
- Subscription that is difficult to cancel., with a flow designed to confuse.
Two precautions arise from this. First: The app that was removed from the store remains installed on your device. — Removing an app doesn't uninstall anything, and it's worth checking if any you use have disappeared by searching for them. Second: if an app in this category has disappeared, find out why before installing the "alternative version" that appears on some website. That's exactly what you don't want.
Frequently Asked Questions
Can I use two cleaning apps at the same time?
You can, but there's no advantage. They essentially do the same job and, running together in the background, consume twice the resources to deliver the same result. Choose one, use it when you need it, and uninstall the rest.
Does the paid version unlock any cleanup features that the free version hides?
Normally not. The subscription removes ads, allows scheduling, and unlocks extra reports. The set of files that can be deleted is the same, because it depends on the permissions that Android grants, and not on the plan subscribed to.
Why have some of the popular apps on this list disappeared from the store?
Apps are removed when they violate platform rules, and the most common reason in this category is abusive advertising — ads displayed outside the app or at inappropriate times. When this happens, the program stops receiving updates and should not remain installed.
Do I need an app like that on my iPhone?
No. Apple's system doesn't allow apps to freely access other apps' files, so tools of this type can't function like they do on Android. Cleaning on the iPhone is done through the system's own storage settings and the internal storage managers of each app.
What's the first thing to do before installing any of them?
Open Settings > Storage and note the amount of free space. This number is your benchmark. Without it, you're dependent on the result the app claims to have achieved, which usually includes cache that the system would clear on its own anyway.
Conclusion
For most people, Files by Google does the job. Those who want fine-grained control choose SD Maid; those who like detailed reports use CCleaner; those with a gallery full of similar photos take advantage of AVG Cleaner; and those with many installed applications can try Avast Cleanup. In all cases, the value lies in the file management aspect — and the first cleanup is still the one you do on the Android storage screen itself.
