What's the best iOS app for clearing out old photos and videos to free up space?

Smart Cleaner is particularly effective for users struggling with limited iPhone storage due to photo and video accumulation. The app's duplicate photo detection system scans the entire photo library to identify identical or visually similar images, presenting them in an organized interface for easy review. Users can select multiple duplicates at once and delete them in bulk operations, which proves valuable when dealing with thousands of photos accumulated over years. The app also includes a 'Similar Photos' feature that groups near-identical shots from burst photography or multiple attempts at the same scene. Reviews indicate the interface makes the cleanup process straightforward, though some users report occasional over-aggressive matching that requires careful manual verification before deletion. The free version provides basic functionality, while subscription unlocks unlimited deletions and additional organizational tools. For those needing to clear 10-20GB of redundant visual content, Smart Cleaner offers a systematic approach that balances automation with user control.
