Short answer
Clever Cleaner cleans the whole library: duplicate and similar photos (best shot marked), large videos, Live Photos to stills and compression, with screenshots as one category; its page cites generous free daily limits, no ads, no mandatory subscription and local processing. ScreenStack handles only the screenshots themselves: sorted by purpose, codes and order numbers searchable and copyable, a receipt before deleting and an in-app trash. To free space, use Clever Cleaner; to delete with confidence and still find things, use ScreenStack. Third-party facts checked 2026-10-16.

When to pick Clever Cleaner
- You clean the whole library: duplicate and similar photos, big videos and Live Photos, with screenshots only part of it.
- You want to free space within the free limits and see no ads.
- You want the tool most users have vetted; it has the most ratings in this group.
When to pick ScreenStack
- You only want to manage screenshots and first keep codes, order numbers and transfer records as searchable fields before deleting.
- You want a receipt before deleting and an in-app trash so mistakes can be recovered.
- You want screenshots sorted automatically into Important, Favorites, Casual and To sort.
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
- Import into ScreenStack and note the number waiting to be sorted, then check the screenshot count in Clever Cleaner and compare.
- Pick a screenshot with a verification code and read the receipt in ScreenStack before deleting, to feel the difference a receipt makes.
- Estimate how much of your library is duplicates and big videos: if they dominate, Clever Cleaner pays off more.
Moving over from Clever Cleaner, or using both
The two apps do not touch each other's data, so there is nothing to migrate: Clever Cleaner deletes from the system library, while ScreenStack imports incrementally from the system screenshot album. A sensible order is to run through screenshots with value as credentials in ScreenStack first, which keeps an in-app copy of originals worth keeping, then use Clever Cleaner for duplicates and big videos. Clearing screenshots with Clever Cleaner first means the fields can no longer be recovered.
