How to do it

Open Similar photos

Pick what to keep, group by group
PicWay puts what it thinks is the best shot first, and you choose. Tap Keep on a photo to mark it, then tap the button below to keep what you marked. To keep everything, tap Keep all. To keep nothing, tap Set all aside.

Review in Set aside, then decide
Open Set aside and look through them again. Tap Put back at the top right of any you want to keep. If you delete two or more at once, PicWay first asks you to confirm the count. Tap Continue deleting, and iOS asks you to confirm.

Similar photos vs. Duplicate items
Similar photos are several shots of the same moment, each a little different, so you choose which to keep. Bursts of the same scene count here too.
Duplicate items are exact matches of a photo or video. There’s less to choose: on the Duplicate items page, tap the button to keep one per group. PicWay keeps the one you favorited, or else the earliest, and sets the rest aside.
The Photos app on iPhone can handle duplicates too: open Duplicates under Utilities in Collections and tap Merge (Apple’s guide). See how to remove duplicate photos on iPhone for more, and PicWay vs. the Photos app to compare the two.
Why don’t I see the card yet?
Finding similar and duplicate photos takes a while, and longer with a bigger library. Turn on Background App Refresh in the iPhone Settings app so PicWay can keep looking while your iPhone is idle. Without it, PicWay still works, but the search pauses while your iPhone is locked, and Similar photos may not find everything.
To see whether it’s on, open PicWay’s settings, then tap Photos & iCloud. The Background processing section shows the Background App Refresh status.
Can I recover what I deleted?
Yes. Deleted photos go to Recently Deleted in the Photos app, and you can recover them for 30 days. You recover them in the Photos app. PicWay can’t empty Recently Deleted for you.
