AI Cleaner - Phone Cleaner

Review by eFreeware

If your phone is the place where every photo, video and email ends up, and the storage warning keeps coming back no matter how often you delete a few things, this app is built for you. AI Cleaner is a free Android utility from GRIMLAX TRADE, S.L. that gathers the usual cleanup jobs into one place: finding duplicate photos, shrinking large media files, emptying a crowded inbox, merging duplicate contacts and hiding private files behind a vault.

The pitch is that you stop hunting through folders yourself. Instead of scrolling your gallery looking for near-identical shots, you let the app scan and present what it finds. That is the appeal of a tool like this: it turns a chore you keep postponing into a short session of confirming suggestions.

It has found a large audience already, with more than 10 million installs and a 4.3 average across 328,299 ratings. Those numbers suggest plenty of people wanted this exact combination of jobs done for them, and the app is free with ads and in-app purchases.

The phone owner this suits

The clearest fit is someone who takes a lot of photos and videos and rarely deletes them. Camera rolls fill with bursts of the same scene, screenshots nobody needs and clips that were funny once. If that describes your phone, the duplicate and similar media cleanup is the part that will earn its place, because it does the comparison work you would never do manually.

It also suits anyone whose inbox has become a storage and attention problem. If you have thousands of unread messages and no intention of reading them, the email features address a real mess.

It also suits people who want one utility rather than five. Contacts, calendar events, unused apps and private files are all handled inside the same app, which keeps the cleanup routine in one place. What it is not is a deep system optimizer for people who enjoy tuning a device themselves; it is a set of practical housekeeping tools with a simple goal.

Finding duplicate and similar media

The gallery side is the core of the app. It scans your photos and videos, detects duplicates and near-duplicates, and lets you remove them with a tap. It also flags old, blurry or poor-quality shots, which is the kind of cleanup most people never get around to because judging each image takes time.

Compression sits alongside the deletion tools. There is a photo compressor and a video compressor, and for video you can choose the compression quality, so you decide how much size to trade for how much visual fidelity. The developer's framing is that you can reclaim space without losing the memories themselves, which is the reasonable way to think about it: compression always involves some judgment about what quality you can live with.

The useful mental model is a routine rather than a one-off purge. Photos accumulate continuously, so the app is most valuable if you run a scan every few weeks, clear what it finds and compress the largest files before they pile up again. That keeps the gallery manageable instead of forcing a painful cleanup once storage is nearly full.

Inbox, contacts and calendar tidy-up

The email cleaner is the newest addition, and it is aimed at volume. You can remove spam, newsletters, promotions and unwanted messages in bulk, unsubscribe from mailing lists you no longer want, and clear out old mail without opening each message.

Contacts get similar treatment. The app finds duplicate entries, merges duplicate numbers into a single contact and removes incomplete records, so your address book reflects people rather than accumulated sync errors. Anyone who has changed phones a few times knows how quickly the contact list becomes a museum of outdated entries.

Calendar cleanup is narrower but welcome: past events that clutter your schedule can be deleted to free space. It is a small feature next to the media tools, yet it fits the same idea of clearing out what has already served its purpose.

App manager and private vault

The app manager shows how much storage each installed app occupies and highlights the ones you have not opened in a long time. From there you can uninstall unused apps directly, which removes the step of digging through system settings to find the same information. For anyone who installs apps casually and forgets them, this is where a surprising amount of space tends to be hiding.

The secure vault takes the opposite approach: instead of deleting, it hides. Photos, videos and contacts can be moved into a private gallery area and accessed when you need them. That is useful for files you want on the device but not visible to anyone glancing at your screen, whether that is personal documents, family photos or work material.

Together these two features cover both directions of cleanup. One reduces what you keep; the other protects what you keep. Neither is unusual on its own, but having them in the same app means you are not juggling separate tools for storage management and privacy.

What it costs and what comes with it

AI Cleaner is free to download. The app contains ads and offers in-app purchases, so there is advertising and the option to spend money inside the app.

What matters practically is that you should expect a free utility with purchases available if you choose them. I would treat that as normal for this category rather than a warning sign, but it is worth knowing before you install, because cleanup apps are used repeatedly rather than once.

The app was released in February 2025 and last updated in September 2026. A tool that handles your photos, mail and contacts needs to keep pace with Android changes, so the update history is a reasonable signal.

Other routes to the same result

The alternative is doing each job with a dedicated tool. A gallery app can handle duplicate detection, a media compressor can shrink videos, your email provider's own interface can handle bulk deletion, and your phone's settings can show app storage. None of that costs anything extra, but it means several different places to visit and no single scan that covers everything.

There is also the manual approach, which is free and thorough but slow. Deleting duplicates by eye, deciding which videos to compress and pruning contacts one by one works, and some people prefer that control. The trade-off is time, and it is the reason tools like this exist in the first place.

A third option is a broader system utility that bundles cleanup with performance features. If you want storage housekeeping and nothing else, AI Cleaner's focus is the point; if you want a general-purpose optimizer, a wider tool may match your habits better.

A practical choice for a crowded phone

AI Cleaner is worth installing if your storage fills up faster than you can manage it and you would rather confirm suggestions than hunt through folders. The combination of duplicate media detection, compression, email and contact cleanup, an app manager and a private vault covers the chores that most often get postponed, and it does so in one free app.

Someone with a tidy gallery and a clean inbox will find little to do here. Someone who takes hundreds of photos a month and never deletes anything will find plenty.

For that second group, this looks like a sensible addition to a phone maintenance routine. Run it periodically, clear what it finds, compress what is large and keep the vault for files you want protected, and the storage warning should stop being a recurring problem.
