Lessa: Find Similar Photos

Lessa helps you clean up your photo library by finding duplicate and similar photos, so you can keep the best shots and reclaim valuable storage.
Your photo library can quickly fill up with multiple photos from the same moment — slightly different shots, repeated images, and photos you no longer need. Finding them manually can take a lot of time. Lessa makes it easier.
Find similar photos: Lessa scans your photo library and groups photos that look similar, helping you quickly spot shots you may want to remove.
Choose what to keep: Review each group and compare your photos before deciding what to delete. You stay in control of every deletion.
Smart Select: Let Lessa help identify photos that may be better candidates for removal, then review the selections yourself before deleting anything.
See your potential savings: Lessa shows how much storage you could potentially reclaim from the photos found during a scan.
Fast, private, on-device processing: Your photos are analyzed directly on your iPhone. Lessa does not upload your photos or photo-library data to an external server.
Works with your Photos library: Lessa can scan your iPhone photo library, including iCloud Photos and Shared Library content when available through Apple's Photos framework.
Clean up your photo library, keep the memories that matter, and make more space for what comes next.
Lessa — More space for what matters.
