We built Culr because we didn't trust the alternatives

The moment we knew something was broken

Before Culr existed, I had 12,000 photos on my phone. Not as a hoarder. As a developer who knew I should clean up, but didn't. Every existing cleaner I tried felt like it wanted to scare me into action. 'YOUR PHONE IS RUNNING OUT OF SPACE.' 'DELETE NOW OR LOSE PERFORMANCE.' Scareware dressed as utility.

Then I'd open the app and face a grid of a thousand thumbnails with checkboxes. No thanks. I wanted to swipe through my actual roll, say yes or no to each photo, and move on. That's what Culr does. Nothing more theatrical.

The real problem wasn't the interface, though. It was trust. I'd read stories about people losing irreplaceable photos because an app deleted something that hadn't synced to iCloud yet. So we built the iCloud status check first. Before every delete, Culr checks whether that photo has synced. If it hasn't, the delete is blocked. We show you the status right there. It costs nothing in performance, but it costs everything in peace of mind.

What made us different from day one

We made three commitments early and kept them. First, no weekly billing. You'll see subscription apps that try to trap you in a weekly cycle. We don't do that. Plus tier is £3.99 a month or £29.99 a year. Pro is £6.99 a month or £49.99 a year. If you want to own it outright, both tiers have lifetime options. That's the deal.

Second, no ad SDKs. We don't know who you are, and we don't sell that knowledge. The app works entirely on your device. Your photos never leave your phone unless you upload them yourself to iCloud or Google Photos.

Third, we focused on photos only. We're not trying to be a file cleaner, a RAM booster, or a junk remover. That's not a limitation. That's focus. It means every feature we add is really about photos, not about artificial reasons to scan your device.

The Free tier handles the basics: swipe through your camera roll, delete what you don't want, clean up screenshots. You get 50 duplicate deletions a month and WhatsApp media detection. For most people, that's enough.

Why photographers actually switched to us

Wedding photographers and event shooters started using Culr early. They had a specific problem: culling 2,000 photos down to 200 keepers in a few hours, and they needed to do it fast and safely.

Most cleaners couldn't help them. So we built Photographer Mode. It groups your photos by shoot, using a 2-hour gap as the boundary. You swipe through each shoot, cull to the keepers, move to the next one. Per-frame sharpness scores help you spot the sharp ones in a burst. And if you're between shots, Culr highlights the likely keeper so you don't have to think about every frame.

We also built burst photo ranking. When you take a burst, every frame has a sharpness score. The best shot gets highlighted. You can see at a glance which frames are soft, which are sharp. Delete the rejects in one swipe.

One photographer sent a screenshot of her freed storage: 47GB in two days. She wrote, 'I finally felt like I could trust the app to not wreck my archive.' That's the core of what we built.

The features that solve real problems

We use Apple's Vision framework to find similar photos and group them. You see a grid of all the near-duplicates from your roll. You keep one, mark the rest for deletion. Simple. The Plus tier unlocks unlimited duplicates (the Free tier gives you 50 a month).

Blur detection works using CIEdges sharpness scoring. We don't use neural networks to guess which photos are 'bad'. We measure the actual edge definition in the image. If a photo is soft, you see it. You decide if it stays.

WhatsApp and Telegram media detection is a big one in the UK. Many people receive hundreds of photos through chat apps, and they pile up in your camera roll. Culr finds all of them and lets you bulk-delete in seconds. No confirmation dialogs for each one. Just load, review, delete.

The Storage Analytics dashboard shows you what's eating your space. We chart 14 days of freed bytes so you can see the impact of cleaning. A simple Swift Charts view breaks down your library: how many videos, bursts, screenshots, duplicates. Helps you understand what's actually taking up room.

Scheduled auto-clean runs in the background daily, weekly, or monthly. It handles your screenshot cleanup and burst archiving without you opening the app. Everything is private and local.

What we didn't do, and why that matters

We didn't add a cloud backup service because that's a different product. You want to back up your photos, use iCloud or Google Photos. Culr's job is to help you figure out which ones to keep and which to delete.

We didn't build in social sharing or memory creation or nostalgia features. Those are nice ideas, but they're not what you came for. You came to clean up. We do that.

We didn't use aggressive dark patterns to push you toward the paid tiers. The Free tier is real. You can cull your entire roll, clean screenshots, and detect WhatsApp media forever without paying. The paid tiers add duplicate deletions beyond 50 a month, similar photo grouping, blur detection, burst ranking, and the Pro features like Photographer Mode and scheduled cleaning. If you have 5,000 photos and you've never used a tool like this, start free. You'll know pretty quickly whether you need more.

Most importantly, we didn't try to convince you that your phone is in danger. Your phone is fine. Your camera roll is just full. We help with that.

The question we hear most

People often ask whether Culr is safer than other cleaners. The honest answer: we've made specific choices that we believe reduce risk. The iCloud sync check is real and it works. We don't use cloud storage. We don't track you. We don't try to be clever with AI recommendations that might delete something you wanted to keep. We show you every photo and let you decide.

But the biggest safety feature is the one people don't think about: undo. You swipe delete, and it goes to a local deletion queue. You can undo before you confirm the batch. If something slips through, you can usually recover it from Recently Deleted on iOS or your Google Photos trash on Android. We're not going to promise that nothing will ever go wrong. But we've tried to make sure nothing goes wrong at our end.
