I recently tried the Cleaner Guru app to speed up my phone and clear storage, but I’m unsure if it’s actually helping or just taking up more space and money with in‑app purchases. Has anyone else used this app long term, and can you share if it really improves performance, battery life, and storage, or if there are better, safer alternatives I should switch to?
Used Cleaner Guru for about a month on my old iPhone and then nuked it. Short version. it did not help enough to justify the space or the subscription.
Here is what I noticed:
-
Storage “cleaning”
- It mostly finds cache, temp files, and duplicate screenshots.
- iOS and Android already manage cache. When you remove cache, apps rebuild it. Storage creeps back.
- I ran Cleaner Guru, freed about 3–4 GB. Two weeks later, almost all of it was back from normal use.
- The “smart cleaning” for photos kept trying to flag live photos and similar shots I still wanted. I had to double check everything, which took time.
-
Performance
- No real speed change.
- Phone felt the same after a day. System processes and hardware limit performance more than junk files.
- RAM cleaners do little on modern phones, since the OS manages memory.
-
Battery
- Background scans and notifications used battery.
- After uninstall, my battery stats showed less background activity.
-
Money
- The free version is nag-heavy. Constant popups to subscribe.
- Subscription is not cheap for what it does.
- You can do most of it manually in Settings:
• Offload unused apps (iOS) or uninstall and reinstall large apps.
• Clear cache per app in Android settings.
• Use Google Photos or iCloud and remove local copies.
• Sort your gallery by size and delete big videos.
-
Space used by the app
- App itself took a couple hundred MB including its own data.
- So you install something to “save space” that also takes space and wants a subscription.
If you want something practical to try now:
-
On iPhone:
- Settings > General > iPhone Storage.
- Follow the system suggestions, like offload unused apps and review large attachments.
- Delete old message threads with lots of media.
-
On Android:
- Settings > Storage > Free up space or similar.
- Use Google Files “Clean” tab instead. It is free and low nag.
- Clear cache from one or two biggest apps in Settings > Apps.
If you see no noticeable change in speed or storage after one or two Cleaner Guru runs, and you are paying or thinking of paying, I would cancel and rely on built-in tools. The app feels more like a subscription wrapper around stuff your phone already does.
Had Cleaner Guru on my main iPhone for about two months and ended up canceling the sub, but my take is a bit softer than @cacadordeestrelas.
What it actually did for me:
- The “merge contacts / clean contacts” part was the only feature that felt remotely useful. If your address book is a mess with lots of partial dupes, that tool can save some time. Still risky though, because it occasionally merged stuff that really shouldn’t be together (coworker + personal number, etc.), so you have to review carefully.
- The photo cleanup suggestions were like 60% helpful, 40% sketchy. It did surface a bunch of accidental screenshots and true duplicates that I had forgotten existed. But it also kept flagging “similar” selfies and low‑light photos I actually wanted. After a while the review process felt like doing the job manually anyway.
- Performance gains were… placebo at best. Apps didn’t open faster in any consistent way. Sometimes right after a “deep clean” it felt snappier, but if you measure load times they’re basically the same. Modern iOS/Android just don’t gain much from this kind of thing.
- Storage gains were very bursty. First run: freed a few GB. By the end of the month a lot of that space had crept back from normal app usage and cached media. The cycle becomes: “Run app, feel good, watch it slowly fill again.” Psychologically satisfying, technically kind of pointless.
Where I slightly disagree with @cacadordeestrelas is that I did find it marginally convenient as a “dashboard” for what’s taking up space. For less techy folks who never open Settings, having one place that says, “Here’s your bloated apps, here’s duplicate media, here’s old big files” can be less intimidating than poking around system menus. But that convenience is not worth an ongoing subscription for most people.
Stuff to check before you keep paying:
-
Run it once, write down:
- How much storage it claims to free.
- What exactly it deleted.
- Your free space after.
Then don’t run it again for 10 to 14 days, just use your phone normally. If the space is mostly gone again, all it’s really doing is temporary cache shaving with a nice UI.
-
Ask yourself what you actually value:
- If you want speed: this is the wrong category of app. You’d be better off removing heavy apps you never use, updating the OS, and not running a bunch of junk in the background.
- If you want more space: a one‑time manual cleanup plus better photo backup habits beats a subscription every single time.
- If you want “set and forget” peace of mind: this app tries to sell that, but you still end up reviewing deletions to avoid losing stuff.
-
Watch for these red flags:
- Constant “you’re almost out of storage / your phone is at risk” warnings that feel pressuring.
- Super limited free tier where every button funnels you to “Start free trial.”
- App size creeping up over time as it stores its own logs and data.
If you’re already on the paid plan and not seeing obvious benefits, I’d:
- Cancel the sub now so it doesn’t renew.
- Keep the app installed for the remainder of the paid period if you want, do one more heavy cleanup focused on duplicate photos and contacts.
- Export or double check anything important, then uninstall and rely on your phone’s built‑in tools after.
Cleaner apps in general are very good at selling the feeling of doing maintenance and very bad at changing long‑term reality. If your phone was truly unusable from low storage, it can give you a temporary breather. For ongoing monthly value though, it’s pretty hard to justify.
