Short answer
SnapCleaner's page is brief: it cleans screenshots, duplicate and similar photos, blurry photos and large videos, uses AI to spot useless screenshots, lets you swipe left to delete and right to keep, and shows quick space analysis. ScreenStack does not guess what to delete: it sorts screenshots by purpose, extracts credential fields so they stay searchable, shows a receipt before deleting and leaves the decision to you. SnapCleaner requires iOS 26.1, while ScreenStack runs from iOS 17. For the fewest taps pick SnapCleaner; to delete with confidence and still find things, pick ScreenStack.

When to pick SnapCleaner (AI screenshot cleanup)
- Your iPhone is on iOS 26.1 or later and you want AI to find useless screenshots and blurry photos in one pass.
- Your only goal is freeing space and you do not need to keep credential fields.
- You like quick left-right swipes and want a Chinese interface.
When to pick ScreenStack
- Your iPhone is on iOS 17 to 26.0 and cannot install SnapCleaner.
- You want to keep verification codes, order numbers and transfer records as searchable fields before deleting, with a receipt and a trash.
- You want free core features with Pro as a one-time purchase, not a subscription first.
Limits of ScreenStack
- ScreenStack is iPhone only with no Mac version, and it does not create notes; to turn what is inside screenshots into expenses and to-dos, look at ScreenNote.
- Importing, sorting, on-device OCR search and basic cleanup are free forever; smart cleanup (grouping by visual similarity) and the credential wallet are Pro, a one-time purchase.
- Its scope is the screenshots themselves, not duplicate photos and large videos across the whole library.
Three things to test yourself before you commit
- Check your system version first: Settings → General → About; below iOS 26.1 SnapCleaner will not install.
- Take a batch of 50 old screenshots, see what SnapCleaner suggests clearing and whether you agree.
- Pick one with a verification code and try the receipt and trash in ScreenStack, then decide whether you want that safety net.
Moving over from SnapCleaner (AI screenshot cleanup), or using both
SnapCleaner deletes straight from the system library and leaves no data to migrate. Before using it, let ScreenStack import the system screenshot album once: screenshots worth keeping as credentials get an in-app copy of the original. After cleanup the originals are gone from the library but the fields and copies in ScreenStack remain searchable. If you later change your mind about a deletion, ScreenStack's in-app trash and the system Recently Deleted album are the two places to look first, and neither depends on which cleaner you used.
