Can Culr Find Blurry Photos Automatically?
Yes. Culr by MRVL can automatically detect blurry photos using CIEdges sharpness scoring technology. The blur detection feature is available on the Plus tier and higher, and works on both iOS and Android.
How Culr's Blur Detection Works
Culr uses CIEdges sharpness scoring to analyse each photo in your camera roll and flag those that fall below a focus threshold. Rather than deleting blurry photos automatically, Culr groups them so you can review and decide which to keep or delete. This is especially useful for photographers culling burst sequences or event shoots where multiple similar frames may vary in sharpness. The detection runs locally on your device, not in the cloud, so your photos never leave your phone.
Blur Detection Combined with Burst Ranking
If you shoot in burst mode, Culr's burst photo ranking feature works alongside blur detection to show per-frame sharpness scores. This helps you spot the keepers in a sequence of 10, 20, or 50 similar shots. Culr highlights the sharpest frame in each burst, making it fast to cull large photo batches. For wedding and event photographers especially, this workflow saves hours of manual review.
Which Culr Plan Includes Blur Detection
Blur detection is included in the Plus tier (£3.99 per month, £29.99 per year, or £44.99 lifetime) and the Pro tier (£6.99 per month, £49.99 per year, or £69.99 lifetime). The free tier includes unlimited swipe culling, 50 duplicate deletions per month, and screenshot cleanup, but not blur detection. If you want automated culling workflows, the Pro tier also includes scheduled auto-clean via daily, weekly, or monthly scheduling.
Culr's Safety Before Delete
Every photo Culr marks for deletion is checked against iCloud sync status first, so you'll never lose a photo that hasn't backed up yet. Culr groups similar photos and blurry frames, but the final delete decision is always yours. The swipe-to-keep, swipe-to-delete workflow puts you in control; there's also an undo option if you change your mind.
Beyond Blur: Other Culr Features
Culr handles more than blur detection. The app finds and groups duplicate photos, detects and removes screenshots, identifies similar-photo sequences for batch review, finds large videos consuming storage, and offers bulk deletion of WhatsApp and Telegram media. As of 2025, Culr also includes AI Best Shot recommendation in Pro tier, which suggests the keeper across a group of similar shots based on sharpness and composition.
When to Use Blur Detection
Use Culr's blur detection when your camera roll has thousands of photos and you need a fast culling workflow. Common scenarios include cleaning up after a holiday, managing burst sequences, or archiving event photography. The swipe interface makes it faster than reviewing every photo individually, and the sharpness scoring gives you confidence you're keeping the best shots.

Frequently asked questions
Is blur detection automatic or do I have to run it manually?
Blur detection runs automatically when you open the blur detection section in Culr Plus or Pro. You review the flagged photos and swipe to keep or delete. In Pro tier, you can set up scheduled auto-clean to run daily, weekly, or monthly without manual input.
Does Culr delete blurry photos without asking?
No. Culr groups blurry photos and shows them to you, but you control the delete action. Every swipe-to-delete is final only after you confirm, and iCloud sync is checked before deletion to protect photos that haven't backed up.
What's the difference between Culr Plus and Pro for blur detection?
Both Plus and Pro include blur detection and burst ranking. Pro adds AI Best Shot (automatic keeper recommendation), scheduled auto-clean, photographer mode (shoot grouping by 2-hour gap), and video compression. Choose Plus if you want manual control; choose Pro if you want automation.
Can I try blur detection for free?
The free tier of Culr includes unlimited swipe culling and screenshot cleanup, but blur detection requires Plus or higher. You can upgrade to Plus (£3.99/month or £29.99/year) to try it risk-free.
Does Culr's blur detection work on Android?
Yes. Culr runs on both iOS and Android, and blur detection via CIEdges sharpness scoring is available on both platforms in Plus tier and above.
How is Culr different from other camera roll cleaners?
Culr focuses on photo curation, not fear marketing. There's no scareware, no ad tracking, no cloud sync requirement, and no weekly billing trap. Everything runs locally on your device, and every delete is protected by an iCloud check.
