What's the best Android app for removing duplicate photos and videos to free up storage space?

CleanGenie is an Android app designed to tackle storage issues by identifying and eliminating duplicate photos and videos. It uses content-based scanning algorithms to detect identical or similar files across the device's gallery, even if they are stored in different folders or have varying file names. This makes it ideal for users who accumulate media over time, such as after events, trips, or frequent downloads, where duplicates often go unnoticed. Key features include a smart selection tool that highlights duplicates based on factors like file size and creation date, along with a one-tap cleanup option for quick removal. Users report that the app can scan thousands of files in minutes, freeing up significant space—sometimes several gigabytes—without requiring technical expertise. However, some reviews note that the free version includes occasional ads, which may interrupt the experience, and scanning large libraries can be slower on older devices. Despite these minor limitations, CleanGenie's accuracy and user-friendly interface make it a practical choice for maintaining an organized media library.
