How Swipe Cleaning Works: Left to Delete, Right to Keep (and Everything You Can Undo)

The problem

Bulk cleanup tools are efficient and also scary. Ticking 600 photos and pressing Delete means you can’t be sure you didn’t tick the one picture of your grandmother. Going through the camera roll by hand is safe and impossibly slow, and the oldest photos come first, years of shots you’ll agonise over, while the gigabytes are somewhere near the end.

How the deck works

Swipe Clean builds one deck out of everything the scan flagged: screenshots, exact duplicates and near-identical shots.

• Swipe left = delete, swipe right = keep. Or use the buttons.
• A “Keeping” thumbnail is shown in the corner of a duplicate or similar photo. It is the version that would survive if you delete this one, so you’re never choosing blind.
• Each card shows why it was flagged, its size, its dimensions and its date.
• Tap a card for a full-screen, pinch-to-zoom preview.
• Undo takes back your last swipe.
• The bottom bar shows how many photos are ready to go and how much space they free. Nothing happens until you commit from there.

Sort order

The default is Largest First, so a few swipes can already give back hundreds of megabytes. You can also choose Newest First, Oldest First, or Shuffle. The sort order applies to both the photo and video decks.

Deleting

When you commit, iOS shows its own delete confirmation. The photos go to Recently Deleted, where they stay for 30 days, which also means you can recover them. See why space doesn’t come back immediately.

Kept photos are remembered

When you swipe right, the app remembers that decision, as you go, even if you quit halfway. Next time, photos you’ve already kept aren’t offered again, so a second pass only asks about what you haven’t seen. Decisions are dropped after a year, and if you edit a photo it can come back. To see everything again, go to Settings → Reset Review History. When the deck says everything you decided on is hidden, it offers Review Kept Photos for this session.

Grid mode

If you have hundreds of items, use the grid (“expert mode”). It has tabs for Duplicates, Similar and Screenshots, a Select All and a Clear button per tab, and a full-screen preview where you can toggle each photo. Select All keeps the suggested best photo in each group and selects the rest.

Tips

• Do one category at a time rather than mixing, when you’re nervous about deleting.
• Swipe through the first 20 or so slowly to learn how the “Keeping” thumbnail helps.
• Free plan: you can delete one batch of up to 50 MB a day. Plan your batch around it, or see free vs. Premium.

FAQ

Does swiping left delete the photo straight away? No. It marks it for deletion. The photos are removed only when you confirm from the bar at the bottom and then approve the iOS delete prompt.

Can I undo a swipe? Yes, the last decisions can be taken back before you commit.

Will it ask me about the same photos next time? No. Photos you swiped right on are remembered and hidden from new sessions. Use Settings → Reset Review History to see them again. Decisions expire after a year.

Which photos appear first? Largest first by default, so the biggest space savings come in the first few cards. You can sort by newest, oldest or shuffle.
