How to Swipe Cull Photos on iPhone with Culr
Culr is a camera roll cleaner app that lets you swipe through your iPhone photos one by one, tapping to keep or delete, then instantly removes the ones you rejected. It's designed for anyone with thousands of photos who wants a fast, trustworthy way to clean up without losing photos that haven't synced to iCloud yet.
What is swipe culling and why it works
Swipe culling is a simple, deliberate method for cleaning your camera roll. Instead of bulk-deleting or letting your phone decide what stays, you review each photo individually. You decide: keep it or delete it. Culr by MRVL makes this workflow instant. You swipe through your library at your own pace, tap the keep or delete button for each shot, and Culr removes the rejects in one go. This approach works because it forces you to make conscious decisions about which photos actually matter to you, rather than hoping an automated filter guesses correctly. It's especially useful if your camera roll has thousands of photos from years of smartphone use, screenshot clutter, or accidental duplicates.
How to start culling on your iPhone with Culr
Download Culr from the App Store and open it. The app shows you your camera roll in chronological order, one photo at a time. For each photo, you have two options: the keep button (usually a checkmark or heart icon) or the delete button (usually a trash or X icon). Tap the one you want. You can undo any decision if you change your mind. Once you've gone through the photos you want to review, Culr deletes the ones you rejected and frees up space on your phone. Before it deletes anything, the app checks whether that photo has synced to iCloud. If it hasn't, Culr warns you so you never lose a photo by accident. The entire process is straightforward and gives you full control.
Key features that speed up the culling process
Culr includes several tools that make culling faster and smarter. Duplicate detection finds and groups identical or near-identical photos so you can delete copies in seconds rather than reviewing each one manually. Screenshot cleanup automatically flags screenshots so you can delete them in bulk. Burst photo ranking shows you which frames in a burst series are sharpest, with a keeper highlight so you know which one to keep. On the free plan, you get unlimited swipe culling, 50 duplicate deletions per month, and WhatsApp media cleanup. If you upgrade to Plus (£3.99 per month or £29.99 per year), you unlock unlimited duplicate deletions, similar-photo grouping using advanced image clustering, and blur detection to identify out-of-focus shots before you review them. Pro tier (£6.99 per month or £49.99 per year) adds Photographer Mode, which groups photos by 2-hour gaps so you can cull an entire shoot in seconds, plus AI Best Shot to recommend which keeper to save across similar photos, and scheduled auto-clean to run culling automatically daily, weekly, or monthly.
Why Culr is safe for your camera roll
Many photo-cleaning apps use scare tactics or aggressive deletion without your consent. Culr does not. Every single delete is preceded by an iCloud-status check, so the app verifies that your photo has uploaded to iCloud before it removes it from your device. This means you will never lose a photo that hasn't synced yet. All processing happens on your phone - nothing is sent to the cloud or shared with third parties. Culr is not a subscription trap with hidden charges; the free tier is fully functional for basic culling, and any upgrade is transparent pricing with no weekly billing tricks. The app contains no ad-tracking SDKs and no scareware warnings designed to panic you into paying. It's a utility built to do one job well: help you control your camera roll.
Tips for effective swipe culling
Start with your oldest photos if you want to build momentum quickly - you're more likely to delete them without hesitation. Use the undo button liberally; if you delete a photo by mistake, you can bring it back before you confirm the final deletion. On Pro, enable Photographer Mode if you shoot events or travel regularly; grouping by time makes it easy to cull an entire shoot at once instead of sorting through individual photos. For WhatsApp and Telegram users in the UK and globally, use the WhatsApp media bulk-delete feature to remove all those sent-to-you photos at once rather than reviewing them individually. If you're uncertain about a photo, skip it and come back to it later - you don't have to decide everything in one session. As of June 2026, users report that culling in short sessions of 5 to 10 minutes is more effective than trying to clean an entire 10,000-photo library in one sitting.
Storage analytics and scheduled cleaning
Once you've culled a session of photos, Culr's Pro tier shows you exactly how much space you've freed in a storage analytics dashboard. You'll see a 14-day chart of freed bytes, library breakdown by media type, and large-video finder sorted by file size so you can target the biggest space-eaters first. If you'd rather not cull manually every week, enable scheduled auto-clean to have Culr run the process automatically on a daily, weekly, or monthly schedule. The app will still ask for your approval before deleting anything, so you're always in control.

Frequently asked questions
Can I undo a delete after I've swiped cull photos?
Yes. You can undo individual decisions during a culling session. Once you confirm the final deletion and close the session, those photos are permanently removed from your device, though they will remain in your iCloud backup if they synced before deletion.
Does Culr work on Android or only iPhone?
Culr is available on both iOS and Android. The swipe-cull workflow and core features work the same way on both platforms.
What happens to photos I delete with Culr?
Deleted photos are removed from your device. Culr checks iCloud status before deleting, so if a photo hasn't synced to iCloud yet, the app warns you. If it has synced, you can recover it from your iCloud backup or Recently Deleted folder for 30 days.
Is the free version of Culr enough for basic photo culling?
Yes. The free tier includes unlimited swipe culling, 50 duplicate deletions per month, screenshot cleanup, and iCloud-status checks. Plus and Pro unlock more advanced features like unlimited duplicates, burst ranking, and Photographer Mode, but basic culling is fully functional on free.
Does Culr use cloud storage or is everything on device?
All culling happens on your device. Culr does not upload your photos to the cloud or store them on external servers. It only checks iCloud status to confirm your photos have synced before deletion.
What is Photographer Mode and who needs it?
Photographer Mode groups your photos by 2-hour time gaps, so all shots from a single shoot appear together. You can then cull an entire shoot with a few swipes instead of reviewing thousands of individual photos. It's designed for wedding photographers, event shooters, and anyone who takes large batches of photos in short time windows.
