Why Culr exists (and what it isn't)

The problem with 'smart' cleaners

There's a category of app on the App Store called the Smart Cleaner. You know the type: it opens with a red warning screen, tells you your phone is 87% full (it isn't), and offers to delete 'junk' across your entire device. Photos are just one category in a sea of aggressive suggestions.

We looked at these apps when we started. They're profitable. They use scare tactics. They ask permission for everything. And most of them treat your camera roll like it's disposable.

That's not what we built. Culr is obsessed with one thing: helping you sort through photos you've actually taken, keep the ones that matter, and delete the ones you won't miss. Not because your phone is 'in danger'. Because you asked it to. Politely.

The swipe workflow came from frustration, not a design trend

When we first prototyped Culr, we tried the grid approach. Select all duplicates. Tap delete. Confirm. It's fast in theory. In practice, people hated it. You can't see what you're about to lose. You're flying blind at speed.

We switched to a swipe interface because it forces you to make a choice about each image. Left to delete. Right to keep. Undo is one tap if you change your mind. It's slower than bulk deletion, but it's honest. You see every photo. You decide.

That moment when someone from the team sent us a message saying 'I actually enjoyed using this to clear my camera roll' was when we knew we were onto something. Not because it was clever. Because it was human.

The iCloud check that almost didn't make the cut

The photographer from Manchester taught us something. Before we delete anything from your device, Culr checks your iCloud status. If that photo hasn't synced yet, we tell you. We don't delete it. We let you decide what to do.

This feature cost us two weeks of development. It slowed down the deletion flow by milliseconds. Our first instinct was to remove it because 'most people won't notice'. But that's the kind of thinking that leads to lost memories.

Features like this are why Culr is different from a Smart Cleaner. A Smart Cleaner wants to process as many files as possible. Culr wants to process files responsibly. If that means being slower, we're okay with that.

Duplicates, burst photos, and the photographer mode

If you shoot on your phone, you know the problem. You take ten frames hoping one is sharp. You hold down the button on your camera and end up with 47 frames of almost the same moment. Plus you've got duplicates: the original, the edited version, the 'oh I'll fix this later' version.

On the free version of Culr, you get the swipe workflow and 50 duplicate deletions a month. That's enough for casual users. But if you're shooting 5,000 photos a month, that's not enough.

The Plus tier (£3.99 monthly or £29.99 yearly) gives you unlimited duplicate detection plus burst photo ranking. We use per-frame sharpness scoring to tell you which frame in a burst is actually sharp. We highlight the keeper so you don't have to guess.

Then there's Photographer Mode in the Pro tier. We group your shots by a 2-hour time gap. One gesture, and you're looking at all the photos from a specific shoot. Swipe through them, delete the terrible ones, keep the keepers. It's the workflow we'd want if we were shooting a wedding or an event.

What we don't do (and why that matters)

We don't track you with ad SDKs. We don't have a weekly billing trap (the Free tier is free, the Plus tier is monthly or yearly, the Pro tier has a lifetime option). We don't need you to turn your phone into a hot potato of data. Everything happens on your device.

We're also not a cloud backup service. If you delete something from Culr and it hasn't synced to iCloud, that's on you. We warn you. But we don't keep a shadow copy of your photos on some server, charging you monthly to get them back.

A Smart Cleaner pitches itself as a problem solver. 'Your phone is full. We'll fix it.' Culr pitches itself as a tool. It's in your hands. The responsibility is yours.

Storage analytics, scheduled cleaning, and the long view

The Pro tier includes a dashboard. A real one. Swift Charts showing you exactly how many bytes you've freed over the last 14 days. A breakdown of your library by type. Size of your largest videos. You can see the impact of using Culr, not in percentages or vague 'optimization' claims, but in actual data.

You can also schedule auto-clean to run daily, weekly, or monthly. It happens in the background when your phone is idle. It deletes nothing without checking iCloud status first.

We built all of this because we wanted an app we'd use ourselves. And we wanted to know, months later, that it was actually helping.
