Finds the clutter
Screenshots, documents, receipts, whiteboards, cards, and more — grouped into piles, so a full library becomes a short list of decisions.
Get your gigabytes back.
Cleanroom clears the screenshots, receipts and duplicates you don't need, shrinks your biggest videos on your phone's own chip, and seals anything private in the Keep. Your photos never leave your phone.

What a typical cluttered library gives back.
An illustration, not a promise. On your phone, Cleanroom only ever shows what it actually measured in your own library — it never invents a number.
Where the space went
Three ways your storage comes back.
Nothing here is magic. It's the same three piles in almost every library — and Cleanroom weighs each of them in plain gigabytes before you touch a thing.
01 · Clear
The easy deletions
Screenshots, receipts, documents, whiteboards — the photos you took to remember something and never opened again.
02 · Dedupe
The copies of copies
Exact duplicates and near-duplicates — burst shots, re-saves, small edits. Nine near-identical frames of the same sunset become one.
03 · Shrink
The video, halved
Big videos are the single largest bucket of wasted space. Re-encoded to HEVC on your phone — the video stays, the gigabytes don't.
The cleanup
The easy photos to delete, cleared in minutes.
Cleanroom sorts a whole library into piles, tells you what each pile costs in storage, and turns the whole thing into a short list of swipes.
Sort
Duplicates
Copies you didn't know you had
Exact duplicates, plus near-duplicates — burst shots, re-saves, and slightly-edited repeats — found automatically, not just byte-for-byte matches.
Fast Review
One photo, one decision
Swipe through each pile one photo at a time — keep, clear, or send it to the Keep. Nothing is deleted until you confirm the whole batch, and cleared photos pass through Recently Deleted.
Reclaim
Wins back the gigabytes
See what each pile actually costs in storage before you touch it — screenshots, duplicates, oversized video, all weighed in plain gigabytes.
Measure
Never guesses at you
Every flag says what was detected and how sure the detection is. An exact duplicate is "certain"; a maybe is a maybe. Cleanroom reports what it measured — it never invents a number.
Everywhere
iPhone and iPad, properly
One universal app that adapts to the screen it's on — not a stretched-out phone layout. iPhone stays portrait; iPad rotates freely.
Video compression
Watch a gigabyte disappear. The video stays.
Cleanroom re-encodes your biggest videos to HEVC entirely on your phone's own chip — then measures the file before and after, so the saving you see is the saving you got.

Encode, verify, then swap.
A crash can duplicate a file. It can never lose one. Cleanroom writes the smaller copy, confirms it actually plays back, and only then offers to replace the original — and only if you asked it to.
- On your chip. Nothing is uploaded to make it smaller. There is no server to upload it to.
- Measured, not estimated. Bytes before, bytes after. The number is the truth.
- Keep the original, or don't. Your call, every time — and the smaller copy lands back in Photos either way.
Two rooms
Cool where it works. Plum where it keeps.
The app is a cleanroom — clinical, precise, blue-grey — until you open the Keep. Then the whole room changes colour, so you always know which one you're standing in.

The Keep
Some photos aren't clutter. They're sealed.
Move them into the Keep — a vault encrypted with AES-256-GCM on your iPhone or iPad, opened with Face ID, a passcode, or a PIN. Not hidden in a folder. Encrypted, in place, on the device.
- Cipher
- AES-256-GCM
- Key
- Keychain, this device only
- Unlock
- Face ID / passcode / PIN
- You decide what's private. Cleanroom flags photos you might want out of the open grid — the category is called Sensitive, and it decides nothing on your behalf.
- Encrypted, not just hidden. Every file is authenticated as well as encrypted, in 4 MB chunks, and written only after it has been verified to decrypt. There is no recovery server, because Cleanroom runs no servers of its own.
- Never behind a paywall. The Keep never charges rent. What you put inside stays viewable and exportable for as long as the app is on this phone — whether or not you ever spend a cent.
The honest part: the Keep is excluded from iCloud and local backups, and its key never leaves this phone. That's what makes it private — and it means that if you lose, erase, or replace the phone, its contents are gone for good. No backup can bring them back. Export anything irreplaceable to Photos before you switch phones. The app says this too, before you put a single photo in.

It detects
Ten categories. Your call on every one.
Cleanroom sorts a library into ten piles. Eight of them are detections — and each one tells you what it measured and how sure it is. Two are simply facts about the library. None of them delete anything.
-
Sensitive
Photos flagged as possibly sensitive — you decide what to keep. A model on your device raises the flag, and nothing acts on it: nothing is hidden, moved, or deleted on its say-so. This is the pile that can go to the Keep instead of the trash.
Built-in model, on device

Documents
Printed pages, forms, sticky notes — the paperwork you photographed instead of filing. Long past useful, still sitting in the camera roll.
Apple Vision + built-in model
-
Handwriting
Notes, lists, and scribbles on paper — snapped so you wouldn't lose them, then never opened again.
Apple Vision, on device
-
Receipts
Till slips and invoices, photographed for an expense claim that closed a long time ago.

-
Cards
Credit cards, passports, licence plates. Worth finding on purpose — seal them in the Keep, or clear them out of a library that syncs to the cloud.

Whiteboards
Meeting rooms and lecture halls — photographed so nothing would be lost, and never read back.

Screenshots
The easiest pile to clear, and a surprisingly heavy one: screenshots are PNGs — lossless, and far larger than the same image needs to be. Photos tags most of them for you, so this pile is certain rather than a guess, and re-encoding one to HEIC shrinks it hard.
Photos metadata — certain
-
Duplicates
Found by a 64-bit perceptual fingerprint, not a byte-for-byte match — so burst frames, re-saves and light edits count too. An identical fingerprint is certain; a near match tells you exactly how many of the 64 bits differ.
Perceptual fingerprint (dHash)
-
RAW
Not a verdict — a fact read off the library. This original is a RAW camera file, several times larger than the JPEG beside it, and the JPEG is the one you actually look at. Re-encoding a RAW permanently discards sensor data, so Cleanroom never does it unless you ask for it.
Library fact — certain
-
Videos
Usually the single biggest win in a library. Compressing one to HEVC on your phone's own chip keeps the video and gives back most of the space it was taking.
Library fact — certain
Each pile wears its own colour here and in the app, so the two look like the same thing. Nothing is deleted because a category said so — a pile is a suggestion, you review it a photo at a time, and anything you clear passes through Recently Deleted first. The solid square is the Keep: Sensitive photos, and anything else you'd rather not leave in the open grid, can be sealed there instead of thrown away.
Why you can trust the numbers
Every gigabyte you get back is measured on your device — because everything happens on your device.
Every scan and every compression runs on your iPhone or iPad's own chip — no photo is ever uploaded, and there's no account to create or cloud to sync. The only network calls the app makes are non-photo ones: an ad request to Google (which never sees a photo), your own iCloud originals downloading if you use iCloud Photos, and the App Store purchase check. The one-time unlock removes the ad, so you can make the app go quiet.

Questions
The questions people actually ask.
Including the uncomfortable one, answered honestly, because you would find out the hard way otherwise.
Does Cleanroom upload my photos?
No. Your photos never leave your phone. Every scan, every classification and every video compression runs on your iPhone or iPad's own chip, and no photo is ever uploaded — there is no account to create and no server of ours for a photo to go to. To be exact: the app does make network requests that have nothing to do with your photos. The free version asks Google for an ad, the App Store confirms a purchase, and your own iCloud originals download from Apple if you use iCloud Photos. None of them ever receives a photo. The one-time unlock removes the ads, and the ad requests with them.
Is Cleanroom free? What does the purchase get me?
The app is free, and every feature works without paying — the full on-device scan, all ten review categories, Fast Review, the Keep, and video compression. A small ad supports it. Cleanroom+ is a one-time $4.99 purchase that removes the ads and adds a set of extra app icons. Cleanroom+ Family is $8.99 and does the same for up to six people through Apple's Family Sharing. Neither unlocks a feature: nothing in Cleanroom sits behind a paywall, there is no subscription, and there is no trial clock.
What is the Keep — and what happens to it if I lose my phone?
The Keep is an encrypted vault on your device. Photos you move into it are sealed with AES-256-GCM in authenticated chunks, and the key is held in the Keychain behind Face ID, your passcode or a PIN. Now the honest part: the Keep is excluded from iCloud and from local backups, and its key never leaves this phone. That is what makes it private — and it also means that if you lose, erase or replace your phone, everything in the Keep is gone for good. No backup can restore it. Export anything irreplaceable back to Photos before you switch phones. The app tells you this before you seal your first photo.
Does Cleanroom delete anything without asking?
No. Cleanroom only ever suggests. It sorts your library and shows what each pile is costing you in gigabytes, but nothing is deleted, moved or sealed until you select it and confirm the batch. Anything you do delete goes to the Photos app's own Recently Deleted, where iOS keeps it for 30 days — so even a confirmed deletion is reversible for a month.
Does compressing ruin my videos?
Compression only ever applies to videos — Cleanroom never re-encodes a photo. A video is re-encoded to HEVC on your phone, and the app verifies that the new file genuinely plays before it offers to replace the original, so a failed compression can duplicate a video but can never lose one. You choose the preset, and the stronger presets do reduce the resolution to save more space. The app shows you the resolution and the measured size before and after, so the trade is something you can see rather than guess at. Keeping the original is an option, and it is on by default.
Does it work on iPad? Which version of iOS does it need?
Yes. Cleanroom is a single universal app for iPhone and iPad, and it adapts to the screen it is running on rather than stretching a phone layout across a tablet. It needs iOS 18 or iPadOS 18 or later. The interface is available in 23 languages.
How does Cleanroom find duplicates?
It compares what the pictures look like, on your device, using a perceptual hash — a short fingerprint of the image itself rather than of the file. That catches exact copies and near-duplicates alike: burst shots, re-saves, and lightly edited repeats, not only files that are identical byte for byte. Cleanroom groups them, suggests one to keep, and leaves the choice to you.
Still curious? The Privacy Policy lists every byte the app and this website touch, and who handles it.
