CleanTwin scans your local photo library and groups images that look the same or nearly the same. It compares image content (visual similarity, dimensions, capture time, and metadata), so it catches both exact copies and burst-mode look-alikes that have slightly different data.
CleanTwin never deletes anything automatically. You review each group, the app suggests which copy to keep (usually the highest-resolution or most recent one), and you confirm before anything is removed. Deleted items go to the standard Recently Deleted album, so you can restore them within 30 days.
Yes, CleanTwin runs fully on-device. Your photos are never uploaded to a server, never sent to a third party, and never used for training. The scanning model and comparison logic both run locally on your iPhone, iPad, or Mac.
Yes. If iCloud Photos is enabled, CleanTwin works with the local copy of your library. When you delete a duplicate, the change is synced through iCloud the same way it would be if you deleted the photo manually in the Photos app.
Yes. CleanTwin scans HEIC, JPEG, PNG, RAW, and Live Photos. Screenshots are detected as their own group so you can clean them in one pass. Live Photos are matched by their still frame, and the motion track stays attached to whichever copy you keep.
It depends on your library, but a typical user has between 10% and 25% of their photo storage tied up in duplicates, near-duplicates, and similar shots from the same moment. Power photographers and parents who take a lot of burst shots usually see the biggest gains.
Yes. Deletions go through the standard system Recently Deleted album. Open Photos, tap Albums, scroll to Recently Deleted, and recover any item within 30 days of deletion.
CleanTwin is free to download and includes a basic scan so you can see how many duplicates you have. The paid upgrade unlocks unlimited cleanup, similar-photo detection, and the smart "keep best" auto-selection. Pricing is shown inside the app.
