Sweepy for Dropbox app for iPhone and iPad

Sweepy for Dropbox is your personal photo-cleaning assistant! It scans your iPhones photo library, identifies images already backed up to Dropbox, and helps you delete duplicates to free up precious space.

• Smart Detection: Automatically finds photos already uploaded to your Dropbox.
• One-Tap Cleanup: Remove backed-up photos with just a tap.
• Privacy First: No photos are shared or stored elsewhere—your data stays safe.
• Fast and Efficient: Quickly scan and clean large photo libraries.

Disclaimer, by default this only scans photos in your /Camera Uploads directory, which is the default Photo backup directory on Dropbox.
