I like how you can see similar pictures at once. Btw: the size is easily adjustable, which is pretty much necessary.
In addition to showing you very similar pictures, It will show you "similar" pictures that to a human, might be significantly different. People milling around, in different places, etc. That's actually helpful, you probably don't need all of those.
Also notices if you marked as a favorite, if it sees faces, etc.
No worries- you get a 2nd chance to save everything before it actually deletes.Quick & Easy to Use
This is quick & easy to use! It allows me to quickly free up space by deleting duplicate photos.Easy to use
This app is really easy to use. Run it and then review each group of similar photos, choosing which to keep and which to delete. The algorithm sometimes is off, grouping photos taken on the same day and location but with quite different subjects, so you do have to pay attention. Overall it's very helpful in pruning my photo library.
