Swipe through your camera roll, keep what matters, and clear out the rest.
A friendly photo cleaner for iPhone that does all of its work on your device.
Swipe to sort. Photos come up one at a time as a stack of polaroids. Swipe left to move one to the Trash, right to bookmark it, or tap Skip to come back to it later. Tap a card to see it full screen, with pinch-to-zoom and video playback. Undo works for several steps.
Smart groups find the clutter for you. SnapSort scans your library in the background and sorts it into groups:
| Clean up | Browse | ||
|---|---|---|---|
| Similar Shots | Near-identical photos taken together | People | Photos with faces |
| Blurry | Shaky or out of focus | Pets | Furry, feathery, and scaly friends |
| Oops Shots | Too dark, too bright, or taken by accident | Food | Meals, snacks, and treats |
| Screenshots | Saved from your screen | Scenery | Landscapes, skies, and cityscapes |
| Docs & Receipts | Paperwork, notes, and receipts | ||
| QR Codes | Tickets, menus, and links | ||
| Long Videos | A minute or longer, the big space hogs |
Similar Shots picks the keeper. For each burst or retake, SnapSort suggests the best photo based on sharpness, exposure, favorites and resolution. Tap any photo to change what you keep, then trash the rest in one go.
A Trash you control. Nothing leaves your library while you sort. Photos wait in SnapSort's Trash until you delete them, all together with a single iOS confirmation. Deleted photos then go to Recently Deleted in the Photos app for 30 days. You can restore any of them, or select several at once.
Progress you can see. Stats shows the space you've cleared, your daily streak, a 7-day chart, and milestones as you go. Each session has a goal, and Snappy the camera cheers you on when you reach it.
And the small things:
- Reminders: daily, weekly or monthly.
- Widget: a home screen widget with your streak and stats.
- Filters: library filters (Videos, Selfies, Live Photos, Portraits, Favorites and more) plus a year filter.
- Haptics: a light click as a card crosses into a swipe zone, and different feels for bookmarking, trashing, undoing and celebrating. You can turn them off in Settings.
- Looks and layout: dark mode, and an iPad layout.
- Accessibility: VoiceOver actions on every card, keyboard shortcuts (← Trash, → Bookmark, ↓ Skip, ⌘Z Undo), Reduce Motion support, and Dynamic Type.

The photos in these screenshots are original illustrations made for the demo library (see Screenshots).
- Everything happens on your iPhone. Photo analysis uses Apple's on-device frameworks, and the results are stored locally.
- No accounts, analytics, ads, or third-party SDKs. SnapSort has no server and sends nothing anywhere.
- The one exception is iCloud Photos. If your library uses it, iOS may download a full-size original from iCloud when you open a photo, the same as in the Photos app.
| Group | How it's detected |
|---|---|
| Similar Shots | Each photo gets a Vision feature print and a 64-bit difference hash. Photos are compared only with others taken within 5 minutes, so the scan stays fast on large libraries. |
| Blurry | A "re-blur" sharpness measure at 1024 px: a sharp photo changes a lot when blurred, a soft one barely changes. It's combined with Vision's aesthetics score for borderline cases. |
| Oops Shots | Brightness, contrast spread and clipping catch pocket shots and blown-out frames. |
| Screenshots | Photos marked as screenshots by iOS. |
| Docs & Receipts, Pets, Food, Scenery | Vision image classification. |
| QR Codes | Vision barcode detection. |
| People | Vision face detection. |
| Long Videos | Videos of 60 seconds or more. |
Results are cached, so only new photos are analyzed on later launches. The scan also runs as a background task when iOS allows it.
- iOS 18.2 or later. Works on iPhone and iPad.
- Developed with Xcode 27 (beta). Any Xcode with the iOS 18.2 SDK or newer should work.
- Clone the repo and open
SnapSort.xcodeproj. - Pick your team under Signing & Capabilities for the SnapSort and SnapSortWidgetsExtension targets.
- Choose an iPhone and run.
The build runs SwiftLint if it's installed (brew install swiftlint); otherwise it only prints a reminder.
If you build under your own bundle ID, the app and the widget share stats through an App Group. Change group.com.canoe.snapsort in these places:
SnapSort/SnapSort.entitlementsSnapSortWidgets/SnapSortWidgetsExtension.entitlementsConstants.AppGroup.identifierinSnapSort/Shared/Constants/Constants.swift
The background scan identifier in SnapSort/Info.plist and in Constants.Analysis uses the same prefix.
Vision-based groups (Docs & Receipts, QR Codes, People, Pets, Food, Scenery) need a real device, because the Simulator can't run Vision's models. Haptics also only play on a device.
Unit tests use Swift Testing and cover:
- image metrics
- similar-shot grouping
- reminder scheduling
- settings
- analytics (streaks, milestones, restores)
- the Trash
- the haptic patterns
Run them in Xcode with ⌘U, or:
xcodebuild test -project SnapSort.xcodeproj -scheme SnapSort \
-destination 'platform=iOS Simulator,name=iPhone 17 Pro' \
-only-testing:SnapSortTestsSnapSortUITests/ScreenshotTests.swift walks through the app and captures the screenshots above. See docs/screenshots.md for how to run it.
