What Is Similar Photo Grouping in iPhone Storage Cleaners
Similar photo grouping is a feature that automatically clusters visually identical or near-identical photos together, so you can review and delete duplicates in one go instead of scrolling through thousands of individual shots. Culr by MRVL uses Vision framework clustering to group these photos and let you swipe to keep or delete them as a batch.
How Similar Photo Grouping Works
Similar photo grouping uses machine learning to analyse the visual content of your photos and identify shots that are nearly identical. Instead of manually scrolling past each near-duplicate, the app clusters them together for faster culling. Culr groups photos by visual similarity (using Vision feature print clustering), so you see all the similar shots at once. You then swipe to keep your best shot and delete the rest in a single action. This is especially useful if you take multiple shots of the same moment, as many photographers do. The grouping happens on your device, not in the cloud, so your photos never leave your phone.
Why This Matters for Storage
Most iPhone and Android users accumulate hundreds of near-duplicate photos without realising it. Taking multiple shots of the same subject is a natural photography habit, but each duplicate drains your storage. Without grouping, you would need to review each photo individually to spot the duplicates. Similar photo grouping cuts that workload dramatically. Instead of checking 20 similar shots one by one, you see them grouped and can decide in seconds which one to keep. On a camera roll with 5,000 or more photos, this feature alone can reclaim gigabytes of storage in minutes. Culr also pairs similar grouping with burst-photo ranking and AI Best Shot recommendations (in Pro plan), so you can identify the sharpest frame automatically rather than guessing.
Similar Grouping in Culr Plus and Pro
Culr offers similar photo grouping as part of the Plus plan (£3.99 per month, £29.99 per year, or £44.99 lifetime). The feature integrates with Culr's swipe-cull workflow, so you keep or delete grouped photos using the same intuitive gestures you use for other cleanup tasks. If you also want burst-photo ranking and AI Best Shot recommendations to automatically highlight the sharpest photo in each group, upgrade to Pro (£6.99 per month, £49.99 per year, £69.99 lifetime). Pro also includes scheduled auto-clean, photographer mode for shoot-by-shoot culling, and storage analytics to track how many bytes you've freed over 14 days.
What Happens to Your Photos When You Delete
Every time you delete a photo in Culr, the app checks whether that photo has been backed up to iCloud before removing it from your device. This means you never lose a photo that hasn't synced yet. The deletion happens locally on your phone, not via a cloud service, so you remain in full control. Culr doesn't require a weekly subscription, doesn't use ad-tracking SDKs, and doesn't open with scare tactics about your phone being 'in danger'. It's a straightforward photo-management app designed for people with large camera rolls who want a trusted way to clean them up.
Other Features That Complement Similar Grouping
Culr's similar-photo grouping works alongside several other cleanup tools. Duplicate detection finds and removes exact duplicates (50 per month on the free plan, unlimited on Plus). Blur detection (Plus plan) uses CIEdges sharpness scoring to identify out-of-focus shots automatically. Screenshot cleanup removes unwanted screenshots with a tap. WhatsApp and Telegram media bulk-delete clears out old chat media that clutters your roll. Photographer Mode (Pro) groups photos by 2-hour gaps between shots, so event and wedding photographers can cull an entire shoot at once. The storage analytics dashboard (Pro) shows you exactly where your space is going and tracks how many bytes you've freed in the last 14 days. As of 2026, Culr runs on both iOS and Android.
How to Use Similar Photo Grouping in Culr
Open Culr and tap the similar photos section to see grouped shots. Swipe right to keep a photo or swipe left to delete. When you delete, Culr checks iCloud sync status first. If you're on Plus or Pro, enable scheduled auto-clean to run the grouping and other cleanup tasks daily, weekly, or monthly without opening the app. Pro users also see the AI Best Shot recommendation for each group, which highlights the sharpest frame across similar photos. You can undo any deletion by tapping undo before you close the app or run a new cleanup session.

Frequently asked questions
What is similar photo grouping exactly?
Similar photo grouping uses machine learning to cluster near-identical photos together based on their visual content, so you can review and delete multiple duplicates at once instead of scrolling through each one individually.
Do I need to pay to use similar photo grouping in Culr?
Similar photo grouping is included in Culr's Plus plan (£3.99 per month or £29.99 per year). The free version includes swipe-cull, duplicate detection (50 per month), and screenshot cleanup, but not similar grouping.
Does similar photo grouping work on Android?
Yes. Culr runs on both iOS and Android, and similar-photo grouping is available on both platforms with a Plus or Pro subscription.
Can Culr recommend which similar photo to keep?
Yes, on the Pro plan. Culr's AI Best Shot feature automatically highlights the sharpest frame across similar photos, so you know which one to keep without reviewing each shot manually.
Will I lose photos if I delete a grouped photo in Culr?
No. Before every deletion, Culr checks whether the photo has been backed up to iCloud. If it hasn't synced yet, the app warns you so you don't accidentally lose an unbacked-up photo.
Is similar photo grouping the same as duplicate detection in Culr?
No. Duplicate detection finds exact copies of the same photo file. Similar photo grouping clusters photos that look nearly identical but may have slight differences (e.g., different exposures of the same moment). Both features work together to clean your camera roll.
