Smart Cleaner
Smart Cleaner still gets updates. The last one was 15 January 2026, and the app has been out since 2019. It cleans four things: duplicate photos, big videos, Gmail and contacts. The store page leaves out two things. It needs iOS 16. And it eats 116 MB before it frees a single one.
Which one you should install
It cleans more than any other app here, Gmail included. Pick it if you have room to install it.

What it actually does
Most iPhone cleaners do one job. Smart Cleaner does four in one app. That is the main reason to pick it.
- Duplicate and similar photos. It scans your photos, groups the near-copies, picks the sharpest one, and deletes the rest in one tap. This is where most of the freed space comes from.
- Video handling. Big clips are the second biggest eater of space after photos. It finds them and lets you shrink or remove them.
- Contact merging. It finds and merges double entries. Barely helps storage, but it tidies things up.
- Email cleanup. It deletes mail in bulk and unsubscribes you from lists. Rare for a storage app.
- Compression. It shrinks files instead of deleting them, so you keep the content and get the space back.
Three limits worth knowing
You install a 116 MB app to fix a full phone. If you have a few hundred megabytes left, you may have to delete something just to make room for it.
The release notes say little more than "we fixed some bugs". Years into a product, a list of what actually changed would be reasonable.
The store says "Free". You only see the real price after you install and sign up. We are not giving a number here, because Apple does not publish one, and a made-up number is worse than none.

Why ours ticks fewer boxes. We left out video squeezing and email cleaning on purpose. Both need big chunks of code on the phone. That code is what pushes these apps past 150 MB. Leaving it out is how SmartClean stays at 51 MB and still runs on iOS 13. If you want all four jobs in one app, and your phone can take it, Smart Cleaner is the better buy. We are not going to pretend otherwise.
Read it straight: Smart Cleaner has 20,023 ratings against our 32, so on track record it is far ahead of us. Where ours wins is size and older iPhones. If your phone is new and has room to spare, Smart Cleaner is the stronger pick.

Questions people ask
Is Smart Cleaner safe?
On the App Store since 2019, published by a named company with a public website, and it passes Apple's review on every update, most recently 15 January 2026. That is not an independent security audit, and we have not run one. Deletion is irreversible, so review the selection before confirming.
Is it really free?
The download is. Full cleanup needs a subscription whose price is not published in the App Store catalogue, only inside the app. Check it on the subscription screen before agreeing.
How much space will it free?
Depends entirely on how many duplicates and large videos you have, so any figure here would be invented. Its own scan shows the number before you delete anything.
Will it work on my old iPhone?
Only on iOS 16 or later, which means iPhone 6s and newer. Anything older cannot install it.
Smart Cleaner or Cleanup?
Cleanup has 693,974 ratings against 20,023, and it is bigger at 166 MB. Both do the same core job. See the table above.
