Find what's actually taking up space
Six ways to find the things you won't miss — sorted so the biggest win is the first thing you see.
Exact duplicates
The same shot saved twice. Found by comparing the files themselves, not by guessing from names or dates.
Lookalikes
Bursts and near-identical retakes, grouped together so you can keep the best one and clear the rest.
Screenshots
Including the ones iOS never tagged — saved out of Messages, or arrived by AirDrop.
Large videos
Sorted biggest first. Or shrink them instead: pick a quality, see what it saves, and watch the copy before anything is removed.
Live Photos
Turn them into ordinary stills. Keep the picture, drop the paired video that's doubling the size.
Blurry and dark shots
Out-of-focus and underexposed photos, plus pictures of receipts and documents you only needed once.
Clean up your mailbox, too
Connect Gmail, Outlook, iCloud, Yahoo, Fastmail or an IMAP account. See message sizes, find large mail and repeat senders, and move only the mail you choose to Trash. Your iPhone connects directly to your mail provider.
Review before you clean
Klyn never removes anything on its own. Review photo and mail suggestions before acting. iOS also asks you to confirm photo deletions. Deleted photos sit in Recently Deleted for 30 days; mail moved to Trash stays there until you empty it.
In a group of duplicates one photo is always marked as the keeper, and it can't be deselected by accident.
Private by design
No Klyn server. No Klyn account. No analytics. No tracking. Your photos, videos and contacts never leave your iPhone. Connect a mailbox and your phone talks to your mail provider directly — nothing passes through Klyn.
Pricing
Klyn is free to use, with a weekly allowance: 10 photo or video deletions, 200 mail messages moved to Trash, 1 video compression and 3 contact merges each week. Pro removes the limits and adds moving photos into the private Vault.
