What's the best iOS app for finding and deleting duplicate photos to free up iPhone storage?

AI Cleaner is a storage management tool designed to help iOS users reclaim device space by identifying redundant files like duplicate photos and videos. Its core functionality revolves around automated scanning that detects similar images, blurry shots, and unnecessary documents, which is particularly useful for those with large photo libraries or limited storage. The app offers a free tier supported by ads, enabling basic cleanup without subscription commitments—users can watch ads to unlock cleaning actions, though some reviews indicate occasional prompts for trials after initial use. Specific features include a one-tap junk removal system, detailed storage analytics showing file categories, and a safe deletion process that previews items before removal. For real-world scenarios, such as clearing space before a software update or organizing a cluttered camera roll, AI Cleaner provides a straightforward interface that simplifies the task. However, its reliance on ads might interrupt the workflow for some, and the free version has limitations on batch deletions. Overall, it balances accessibility with effectiveness, making storage maintenance less tedious for casual users.
