Why does iShredder iOS show more free space available for deletion than my iPhone?

The difference exists because iOS manages storage dynamically and often contains hidden, cached, and temporary files that are not always visible in the standard storage overview. When you start the “Delete Free Space” process, iShredder securely overwrites all storage areas that are technically free or recoverable — even if those areas are not explicitly shown by iOS.

The larger amount shown by iShredder makes sure that every potentially recoverable piece of information is thoroughly erased in order to protect your privacy as effectively as possible. This is completely normal and simply means the app is doing an excellent job of keeping your data secure!
