Slidebox alternative: sort photos without the subscription

Updated September 28, 2026 · about an 8-minute read

Slidebox has been sorting iPhone photos since 2015, long before the swipe craze. Its trick was never the swipe alone: with one tap you could file a photo into an album without opening it, compare two similar photos side by side and keep the better one, and undo the mistakes. A lot of libraries have passed through it.

The reasons people search for a Slidebox alternative are usually not about those tools. They are about the price: the App Store listing describes subscriptions at US$4.99 a month or US$49.99 a year, and mentions a one-time purchase option without stating its price. This guide compares Slidebox and PicLoom honestly, including the cases where you should stay with Slidebox.

What Slidebox gets right

It is worth being specific, because the parts that work are the parts an alternative has to match.

• One-tap album sorting. Swipe through your photos and file them into albums without opening the albums. For people who genuinely organize by album, this is the killer feature.
• Side-by-side comparison. Two similar photos next to each other: keep the better one, let go of the other. The decision gets much faster.
• The swipe rhythm. Swipe to delete, favorites, undo. Fast, and a wrong swipe is cheap to reverse.
• Works where your photos live. It works directly with the Photos app and syncs via iCloud, so there is no import step and nothing is trapped inside an app.
• A long track record. On the App Store since 2015, 4.8 stars from about 16,500 ratings. It is maintained, not abandoned.

If that list describes your daily workflow, the honest advice is simple: keep using it.

Where Slidebox stops fitting

None of these are flaws. They are differences in intent that show up after a few weeks of use.

You would rather pay once

Slidebox is free to download with in-app purchases. Its listing describes subscriptions of US$4.99 a month or US$49.99 a year and also mentions a one-time purchase option, without stating its price; the App Store shows current pricing. If you are searching for an alternative precisely to get off the subscription treadmill, check what you are actually buying: a stated one-time price is a different promise than a one-time option mentioned in a listing. PicLoom Pro is a one-time purchase of US$9.99, with your region's price on the App Store.

You need deciding, not filing

Slidebox's superpower is moving photos into albums. But many libraries are not album-shaped. They are ten thousand unsorted photos where the real work is keep or let go. If your question is "do I still need this photo?" rather than "which album does it go in?", the filing machinery is a cost you pay for but never use.

The deletion decision happens at the swipe

A swipe in Slidebox deletes. Apple's system still moves deleted photos through Recently Deleted, so there is a recovery window, but the decision happens at the gesture. Some people prefer a two-step flow: set the photo aside now, confirm the deletion once, after a review.

What any good Slidebox alternative should keep

A replacement is only useful if it keeps what made the original work. Before switching, check for these five things.

1. The same gesture. Left and right, no tiny buttons to aim at.
2. Undo. A wrong swipe has to be cheap to reverse.
3. A review step before deletion. One more look at everything you set aside, then the system confirmation.
4. A way to compare near-identical shots. If you loved the side-by-side view, do not give it up silently.
5. A price model you can live with. Whatever it is, know it before you sort ten thousand photos into it.

How PicLoom compares

PicLoom is a photo decluttering app for iPhone built around the review rhythm: right to keep, left to set aside, undo, and a queue you review before anything is deleted. It also keeps the memory side of the library, in the same app.

Two differences matter most in daily use. First, the price model: Slidebox's listing centers on a subscription at US$4.99 a month or US$49.99 a year, with a one-time option mentioned; PicLoom's reviewing is free for 50 decisions a day, and Pro is a one-time US$9.99 purchase instead of a subscription. Second, what happens after the keep decision: in PicLoom, kept photos can become a calendar day, a written story, or a point in Footprints, instead of sitting filed away in an album.

The trade-off runs the other way too: if your library's main problem is organization, Slidebox's one-tap album filing and side-by-side comparison are genuinely better tools, and PicLoom does not replace them. Apple Photos' own Duplicates album is the free option for exact duplicates. Come to PicLoom for the keep-or-let-go decisions, not for filing photos into albums.

How to switch without losing anything

This part is easier than it sounds, because both apps read the same library. There is nothing to import.

Step 1: finish or clear your current queue first

If Slidebox still has photos waiting to be sorted, sort them or mark them as favorites first. Photos you already deleted live in Photos, not in the app.

Step 2: install PicLoom and grant access

You can allow access to all photos, or only selected ones. Sorting works either way.

Step 3: start with one month, not the whole library

Pick a recent month, or use Time Stroll for an older one. Set aside what you do not need; keep what you do. Nothing is deleted yet.

Step 4: review the queue before it leaves

When you are ready, open everything you set aside, rescue what surprises you, and confirm. iOS shows the final confirmation and Recently Deleted keeps its own recovery window, with the date shown on screen.

If deciding is the hard part, how to decide which photos to keep settles most cards in seconds. And if you are still comparing other swipe apps, the Swipewipe comparison covers the delete-focused side of the family.

Who should stay with Slidebox

• Album organization is your main job, and you use one-tap filing every day.
• Side-by-side similar comparison is the reason you open the app.
• You also sort on iPad and want the same tools there (the App Store listing shows an iPad version).
• The subscription price is fine for you, or the one-time option's price works for you.

None of that is a criticism. The wrong reason to switch is a feature list; the right one is that the app's pace or price no longer matches how you want to treat your library.

Frequently asked questions

Is there a free Slidebox alternative?

Slidebox itself is free to download with in-app purchases, and Apple Photos is free with the device. PicLoom is free to download from the App Store with a daily allowance of 50 review decisions, and Pro is a one-time purchase for unlimited reviewing.

Does PicLoom organize photos into albums like Slidebox?

No. PicLoom is built for keep-or-let-go decisions, not album filing; it does not sort photos into albums. If one-tap album sorting is the feature you use daily, Slidebox is the better tool.

Will I lose anything by switching?

No. Both apps work on the same Photos library, and deletions always pass through Apple's confirmation and Recently Deleted. There is no import step and nothing to move.

Is PicLoom a subscription?

No. Reviewing is free within the daily allowance, and Pro is a one-time in-app purchase (US$9.99 in the US; the App Store shows your region's price). It is not a subscription.

Slidebox earned its reputation with speed: one-tap filing, side-by-side comparison, and a swipe rhythm that has worked since 2015. PicLoom does a different job: the same calm right-and-left rhythm, pointed at what stays. Set aside what you do not need, review it once, and let the photos that stay become days, stories and memories instead of anonymous files. PicLoom is now on the App Store; you can see how the review flow, calendar and story screens work, compare plans on the pricing page, or get it from the download section.
