Bytebye is an iPhone and iPad app that finds duplicate photos, similar shots, screenshots, blurry photos, screen recordings, similar videos and large videos. It shows how much space they take up before you pay anything.

What it finds
Seven kinds of clutter it finds on your iPhone.
Every scan runs on your phone.
Similar photos
Burst shots and near-identical takes where you only ever needed one.
Screenshots
Every screenshot in your library except your Favorites, listed so you can clear the receipts, maps and chat captures you no longer need.
Blurry photos
Out-of-focus and shaky shots, found by measuring how sharp the image actually is.
Screen recordings
Recordings you made once to show someone something, still taking up space long after.
Similar videos
The same moment filmed twice or more, matched by a near-identical frame and nearly the same length.
Large videos
Videos over 100 MB, listed biggest first, so one decision frees real space.
How it works
Scan, review, delete.
Scan
Allow photo access and start a scan. It runs on your phone and shows each category with its size, without asking for payment.
Review
Open a category, look through the items and select what should go. In a duplicate or similar group, one item stays protected.
Delete
Confirm, and the items move to Recently Deleted. Empty that album when you want the space back.
Month by month
Or swipe through your library one month at a time.
Pick any month of your library and swipe through it: left to delete, right to keep. One tap undoes a swipe, and a long press opens any photo full screen or plays any video.
Safe by design
One item in every group always stays.
In every duplicate or similar group, Bytebye protects one item and you cannot select it for deletion. For photos it picks a Favorite, otherwise the sharpest shot, then the highest resolution, then the oldest. For videos it picks a Favorite, otherwise the longest. You can move the protection to another item whenever you disagree. Deleted items go to Recently Deleted, where your phone keeps them for 30 days.
Privacy
Your photos never leave your phone.
No server, no upload
The scan runs entirely on your device. Bytebye keeps a small fingerprint of each photo in a local database so it does not re-read your library every time. Photos and fingerprints are never sent anywhere.
No account
No sign-up, no email, no profile. Open the app and scan.
Ads, said plainly
The free version shows ads through Google AdMob, which receives the device data ads need, and your advertising identifier only if you allow tracking. Premium has no ads and no ad data.
Pricing
Free to scan. Pay once or yearly to remove the limit.
The scan is always free
You see the full result and the measured size of every category before deciding anything. No blurred numbers, no unlock-to-see.
No weekly plan
Two options only: pay once, or pay yearly. Weekly subscriptions gave this category its bad name, and Bytebye does not sell one.
No hidden trial charge
If a plan has an introductory price, the screen says in plain words what you pay now and what you pay later.
FAQ
Common questions about Bytebye.
Is Bytebye free?
Scanning is free and shows the full result. The free version deletes up to 50 items a day and shows an ad after a cleanup. Premium removes the limit and the ads, as a one-time purchase or a yearly plan. Prices are shown in your local currency on the App Store.
Will a payment screen stop me from scanning?
No. The Premium screen opens after onboarding and on some later launches, and it has a close button. Scanning, the full result and 50 deletions a day work without paying.
How accurate is the space figure?
It adds up the file sizes iOS reports for the items Bytebye suggests, and leaves out the item each group protects. The space comes back once Recently Deleted is emptied. If Optimize iPhone Storage is on, some originals live only in iCloud, so your phone may free less than the figure and iCloud the rest.
Does Bytebye upload my photos?
No. Bytebye has no server and no account. Each photo is read on your iPhone and reduced to a small fingerprint for comparison, and neither the photo nor its fingerprint is sent anywhere.
How does Bytebye find duplicate and similar photos?
Bytebye computes a small visual fingerprint for every photo on the device and compares them. Matching fingerprints with the same resolution become exact duplicates; this is a visual match, not a byte-by-byte file comparison, so check before deleting. Close matches from the same session, with no more than three minutes between shots, become similar photos. Videos are compared by one frame and their length.
How is Bytebye different from the Duplicates album in Photos?
On iOS 16 and later, Photos has its own free Duplicates album. Use it if duplicates are all you need. Bytebye also covers similar shots, screenshots, blurry photos, screen recordings, similar videos and large videos, and shows the size of each.
Can Bytebye delete the one photo I want to keep?
Only if you select it and confirm. Every duplicate or similar group protects one item that cannot be selected: a Favorite if there is one, otherwise the sharpest photo or the longest video. You can move that protection to another item, and a group protects only one, so check the rest before deleting. Favorites are never suggested in the screenshot, blurry, screen recording or large video lists. Month-by-month swiping has no protected item, and nothing is deleted until you confirm.
What happens to the photos I delete?
They go to the Recently Deleted album in Photos, where iOS keeps them for 30 days. You can recover them there, or empty the album to free the space right away.
Does deleting in Bytebye also delete from iCloud?
If iCloud Photos is on, yes. iOS syncs the deletion to iCloud and your other devices, and the item stays in Recently Deleted for 30 days. Bytebye itself sends nothing to iCloud.
How long does a scan take?
It depends on your library size and device. The first scan takes longest because every photo is fingerprinted; later scans reuse the stored fingerprints.
Does Bytebye compress photos or videos?
No. Bytebye finds items and lets you delete the ones you choose. It does not shrink or re-encode anything.
Is there a weekly subscription?
No. Bytebye sells only a one-time purchase and a yearly plan. A yearly plan can be cancelled any time in your Apple account settings.
Is there a Home Screen widget?
Yes, in small and medium sizes. It shows your free space and how long ago your last cleanup was. It reads the free space on the device; nothing is uploaded.
Does Bytebye send notifications?
Only if you ask for it. After your first cleanup the app offers a monthly reminder; if you accept, your phone shows one notification 30 days after your last cleanup. It is scheduled on the device, and you can turn it off in Settings.
Which devices does Bytebye support?
iPhone and iPad running iOS 15 or later, including iPhone Duo: unfolded, categories and photos sit side by side. The app is available in nine languages: English, Turkish, German, Spanish, French, Arabic, Japanese, Korean and Chinese.
Who makes Bytebye?
Akaya Labs, the one-person software studio of Ahmet Karaca. That is why the App Store lists Ahmet Karaca as the seller. There is no separate support team: messages to support@bytebye.app are answered by the person who builds the app.
