What's the best iOS app for finding and removing thousands of duplicate or similar photos?

Cleaner Kit is a focused storage management utility designed to tackle the common problem of photo library clutter. For the specific task of removing duplicate or near-identical photos, it operates by performing a visual scan to group similar images. Users can then review these groups in a consolidated view, making it straightforward to select and delete hundreds of unwanted shots in a single action. This process addresses a key pain point for anyone who has accumulated years of photos, screenshots, or multiple takes of the same scene.

Reviews indicate the app is particularly valued for its speed in processing large libraries, which is crucial when dealing with 'thousands of useless pictures.' The interface for batch selection is noted as intuitive, though some users mention a slight learning curve with the selection gestures. A limitation to consider is that the free version has constraints on the number of items that can be cleaned in one session, often prompting an upgrade to a premium tier for extensive cleanups. For a user facing constant 'storage full' warnings primarily due to photos, this app provides a targeted and effective solution, turning a daunting manual task into a manageable one.
