I’ve been seeing a lot of ads for the Cleaner Guru app and I’m not sure if it actually works as well as it claims, especially for cleaning storage and boosting phone performance. Before I pay for any subscription, I’d really like to hear real user reviews—both good and bad. Has anyone used it long term, and is it worth the cost or are there better alternatives?
I tried Cleaner Guru on iPhone for about a week. Short version. I deleted it and asked for a refund.
What it does well:
• Finds duplicate photos by size and date.
• Shows similar photos in groups, so you pick which ones to keep.
• Has a simple interface. You do not need to be techy.
Where it falls apart:
-
Storage cleaning
• iOS already handles a lot of “junk” files.
• Cleaner Guru mostly scans photos, videos, contacts.
• It labels cached data as “junk” but iOS clears that over time anyway.
• After a full “clean”, I freed about 1.2 GB. Doing it manually in Photos and offloading a few apps freed 3+ GB. -
Performance “improvement”
• No third party app on iOS can speed up the phone in any real way.
• What it does is kill background processes and clear memory. iOS does this itself.
• I saw no difference in app loading time or battery life. Zero. -
Subscription model
• The weekly subscription is expensive compared to what it does.
• Free version has heavy limits and aggressive popups.
• Auto renews fast if you forget to cancel. A lot of App Store reviews mention this trap. -
Privacy and permissions
• Needs full access to photos and contacts to “clean”.
• You give a lot of data for an app you might only need once.
• I felt uneasy giving that level of access for something so basic.
Better options that cost nothing:
• Use iPhone Storage in Settings. Sort by largest apps. Offload or delete.
• In Photos app, use “Duplicates” album. Apple added this in iOS 16.
• Sort by “Videos” and delete old clips. They eat the most space.
• Use iCloud or Google Photos for backup, then delete local copies.
• Restart your phone occasionally. That frees RAM and clears temp files.
If you still want to try Cleaner Guru, I suggest:
• Take the free trial.
• Run it once.
• Check how much space you had before and after in Settings.
• Decide if the difference is worth a weekly fee.
• Cancel the trial immediately so you do not forget.
I would not pay a subscription for it. For a cheap one time purchase, maybe. For ongoing payments, no.
Tried Cleaner Guru for a bit on my iPhone too, and my experience lines up with @viajantedoceu on the “not worth a sub” part, but I’ll add a few different angles.
What actually worked for me:
- The “similar photos” detection was decent, especially for burst shots and memes I’d saved 10 times.
- It did surface some old screenshots and screen recordings I’d totally forgotten about. That part actually helped me more than I expected.
Where I disagree slightly:
- For non‑techy folks who never touch Settings, having everything in one app can be less intimidating than digging around in iOS storage menus. I could see a one‑time purchase being reasonable for people who just want a big “clean” button and don’t want to think.
- The UI nudged me to clean videos and Live Photos more aggressively than I would have on my own, so I did free space a bit faster than when I rely on iOS suggestions. But that’s more “guided manual cleanup” than magic.
Big issues I noticed:
-
“Performance boost” is mostly marketing
If your phone is laggy because it’s ancient, Cleaner Guru will not fix that. It might make it feel snappier for 5 minutes after it clears RAM, but iOS just rebalances that anyway. No real, lasting performance gain. -
Space savings are limited
On my test, I got around 800 MB to 1.5 GB back depending on how aggressive I was. When I did a proper manual cleanup later (videos, big apps, old downloads) I freed over 6 GB. The app focuses too much on “photo clutter” and not enough on what actually eats storage. -
Pricing vs value
The weekly subscription is the dealbreaker for me. This is “once in a while” functionality, not “ongoing bill” material. I’d be less annoyed if it were:- A cheap one‑time payment
- Or at most a low yearly fee with some extra smart features
-
Dark pattern-ish behavior
The paywalls and “limited time offer” style screens felt pushy. Easy to see how someone taps through and ends up paying without fully realizing it. Not a fan of that at all.
What I’d do before paying:
- Use the free trial, run it once, then check Settings > General > iPhone Storage before and after.
- Ask yourself: “Would I pay this weekly to press this same button again?” If the answer is no, cancel on the spot.
- Screenshot your subscription page so you don’t “forget” there’s a renewal coming.
Bottom line: It’s not a straight-up scam, it does what it shows on the tin in a basic way, but the subscription model is wildly out of proportion to the actual value. If you’re even slightly patient with manual cleanup, you’re basically paying to be a bit lazier.
If they ever turn it into a cheap one-time utility app, I’d reconsider. As a recurring sub for “cleaning” and “boosting performance,” I’d skip it.
Cleaner Guru sits in a weird middle ground: not useless, not great, and definitely overpriced for what most people actually need.
Where I agree with @hoshikuzu & @viajantedoceu:
- The subscription is the biggest red flag. This is utility-level functionality you might seriously use a couple of times per year, not weekly.
- “Performance boost” is marketing talk. On iOS, there is no legitimate way for Cleaner Guru or similar apps to deliver sustained speed or battery improvements.
- The access it wants (full Photos, Contacts) feels heavy for an app that basically guides you through tidying.
Where I slightly disagree / add nuance:
- For some people, manual cleanup is not realistic. If you have a parent or relative who panics at the Settings app, an “all-in-one clean screen” can actually reduce anxiety. In that specific use case, Cleaner Guru is more of a hand-holding tool than a technical optimizer.
- The “similar photo” logic is not useless. For anyone with thousands of random memes, receipts, and burst shots, the visual grouping can be faster than going through the native Duplicates album alone. It is more like a curated review session than a miracle cleaner.
Pros of Cleaner Guru
- Simple, low-friction interface compared with digging around multiple system menus.
- Decent at highlighting screenshots, similar selfies, and redundant media clusters.
- Good “psychological” effect: makes you actually sit down and clean, instead of ignoring storage warnings forever.
Cons of Cleaner Guru
- Recurring subscription for work you could do occasionally and manually.
- Limited impact on true storage hogs like big apps, offline media, and large games.
- No real way to deliver lasting performance gains despite the advertising.
- Broad data permissions for a task that does not require ongoing access.
- Aggressive paywalls and trial flows that make it easy to forget cancellation.
How I’d actually approach this before paying anything:
Instead of repeating the exact steps already shared, try this approach as a reality check:
- Let your phone get “full” on purpose, then note: which apps genuinely feel slower, and which ones work fine? That gap is often far smaller than ads imply.
- Do one very focused cleanout category you normally ignore, like old downloaded files in third party apps, or big chat backups. Watch how much storage that alone recovers.
- Only after that, test Cleaner Guru’s trial to see if it finds meaningful additional space. If its results are mostly tiny photo duplicates, the value is probably not there for you.
Bottom line on Cleaner Guru app reviews & experiences
Cleaner Guru is not a scam, but the pricing model does not match the actual benefit for most users. It is essentially a guided organizer for your clutter, with some convenience added on top of features iOS already gives you.
If they ever pivot to a cheap one time purchase, I would see it as a decent “training wheels” tool for non technical users. As a recurring subscription built around “cleaning storage and boosting phone performance,” it is hard to justify, especially once you factor in the privacy tradeoff and the limited, mostly short term gains.
