A comment I made recently in a post in r/ProductivityApps got a bunch of upvotes and a few kind comments, so now I've just shipped an update I thought I would make my own post to see if it can reach more people who would appreciate it. It's also a nice change from all the to-do list and note taking apps that I see a lot in this sub.
Curator - Photo Organizer (App Store link) is productive in my eyes because 'sorting out my photos' and 'finally make those family photo albums' was always on my to do list, and it weighed on me constantly, but the task of going into my 30,000+ photo library seemed such a monstrous effort that I never actually did it. Now, I regularly have a little session here and there, my Photos library stays under control and only holds photos I care about. It's the most productive moment of my week.
To be sure that I'm in line with this subs rules: if the flair wasn't obvious, I am the developer behind this app. And to address the concerns around user data risk: Curator is intentionally privacy-first by being completely on-device. No servers, works offline and in airplane mode, because your photos are personal and sensitive - nothing leaves your phone, and it has the 'no data collected' label in the App Store that many similar apps don't. Technically I'm giving up useful analytics for growth and even improvement, but I think it's still a good idea given what its dealing with.
After Christmas last year, I decided to just try cleaning up my library manually within Apple Photos, but it was super slow and annoying, selecting & deleting, and the decision fatigue kicks in really fast. So I looked around at apps I could use to help me, and they were all subscription-greedy tinder style (swipe left & right) apps which I did not want to do over thousands of photos, and particularly because my decision to keep or remove is different depending on whether this is the only photo of my daughter on the swing or whether I took 15 trying to get a good shot. It's usually the latter.
So Curator analyses your photos. The only thing that the on-device AI is really doing is identifying that 'these photos are all of the same thing/moment/scene' even though the photos are up to minutes apart and from different angles and depths, not just near-duplicates. It groups them and then suggests 1-3 'best' photos worth keeping, and you can easily tap to change the selection as you wish. One of the most valuable things it does is reduce decision fatigue: you don't need to decide on every photo - a decision is already made for you, so you'll just 'know' by gut reaction whether you agree or not when you see it, and that goes super fast and is less tiring.
I've just shipped an update which makes the task even more manageable: you can change review modes to limit your session to a month at a time so it doesn't feel endless and you feel progress more, or go through batches of similar photos one after the other so you can see them even more clearly together before making a decision.
Sorry it's turned into a big post in the end and probably needs a tl;dr, but one aspect I haven't mentioned but was actually the reason I started it at all: to make albums. Real, printed albums. There are printing providers that will turn your Apple Photos album into a ready-to-print photo book and deliver it to you, so Curator makes it easy to prepare those albums via the same principle as during the cleanup. It suggests albums based on the best photos from trips and holidays you've been on (reverse-geocoding based on photo meta data) and by time (e.g. per year, per season, Christmas) - and you can edit them (or create your own) the same way as above to quickly end up with an album you'll be happy to have on your coffee table. My 1 and 3 year old love looking through the albums of their first years and first holidays, it honestly made it all worth it.
I'd love feedback if you get a chance, happy to answer any questions - it's free to download and freemium lets you try it out so you can see if you actually like the way it works before a one-time unlock. Truly what would help me more than anything is a quick rating in the app store if you get that far; a pop up might appear some time after using Curator to remove photos or publishing an album to Apple Photos, so taking two-seconds to tap the rating would mean the world to me. Thanks!
