■ Automatic grouping
On-device AI gathers bursts and look-alikes for you. Screenshots, documents, and receipts are sorted out too, so you can declutter your gallery in one pass.
■ AI best pick
Culpix weighs blur, faces, framing, and open eyes to suggest the best shot in each group—and shows you why it stood out, so you can trust the pick at a glance. The final call is always yours, and you can compare two photos up close with a draggable split.
■ Face & expression compare
From a burst or a group of similar shots, Culpix crops the face out of every frame and lines them up side by side, so you can spot open vs. closed eyes and the best expression at a glance. The AI's pick is highlighted to get you started. All on device with Apple Vision.
■ Clean up with confidence
Deleted photos go to Recently Deleted, so they stay recoverable, and your Favorites and protected albums are automatically excluded. Had second thoughts? Undo a cleanup right after you make it.
■ See what's eating your space
The storage analyzer breaks down what's taking up the most room—large videos, bursts, and screenshots—with sizes and counts, so you know where to start. Select what you don't need and delete to reclaim space. Removed items go to Recently Deleted, so you can always get them back.
■ A lighter library, for good
See how much you've cleared right on the home screen. Culpix remembers what it analyzed, so a second pass is much faster—and you can filter groups by type or size, or get a gentle weekly nudge to tidy up. You can even start a cleanup with Siri or Shortcuts.
■ External storage & RAW
Tidy photos on USB or SD drives, and handle RAW+JPG as a single pair. You can also assign a GPS location to your photos.
■ Truly private
All analysis runs on device. No servers, no ads, no tracking—your photos never leave your device.
■ Pro Culling on iPad
Sorting a big shoot? Open a RAW/JPG folder and cull at speed: pick, hold, or reject with one key, rate with stars, and tag with colors, with a live RGB histogram and EXIF right in the sidebar. The viewer reshapes itself around each shot—portrait or landscape—so the photo always gets the most room, and the freed-up space becomes a large contact sheet. On-device AI pre-marks the best frame in each burst. Export the keepers to a folder—copy or move, RAW+JPG kept together, with optional star-grade renaming.
■ Your ratings, ready for the pros
Star ratings and color labels export to XMP, a sidecar file that sits alongside your RAW. Your picks open straight in Lightroom, Capture One, and other tools—no re-rating, no lock-in.
I highly recommend this app if you shoot birds in burst mode. I usually take landscape and bird photos with a Canon R7, and the feature that lets you select burst photos all at once is incredibly convenient. It has significantly reduced the time I spend reviewing and picking photos.
Developer Response
Hello! It's so great to meet a fellow Canon camera user here!If you run into any issues while using the app or have any ideas for new features, please feel free to reach out to me anytime. I actively welcome all feedback.
1.8.2 update - I have fixed an issue where bursts in your photo library could not be found.
■ Burst cleanup
· I have fixed an issue where photos taken in Burst mode with the iPhone camera were not detected as bursts. Culpix now loads every photo in a burst and shows them together as one group.
· If you choose to keep any photo from a burst, the burst's cover photo is kept as well. This is because deleting the cover photo deletes the entire burst.
· For bursts in your Protected Albums, every photo in the burst is now protected.
· Storage analysis now counts a burst's photos and size based on all of its photos.
Thank you to the person who reported this issue.
