I think a really valuable feature in a photo library app would be something that can identify sets of very similar or identical photos and decide which one is the "best" and offer to discard the rest. I must be wasting so much storage on the 4 photos I took in a row of the family pose, or derivatives that got shared on whatsapp and then stored back to my gallery, and so on, and I know I'm not the only one.
Yeah. Lots of “culling” software out there but agree it would be a good feature for standard photo organisation apps https://imagen-ai.com/ https://aftershoot.com/
Aftershoot has culling plan $120/yr billed annually
Not sure how they compare in quality
