Feature set
Similar Photo Grouping & Recommendations
Groups photos with similar capture times and visual content together, providing recommendations based on technical quality such as sharpness, exposure, and facial expressions. Suggestions serve as a starting point—zoom in, inspect details, and freely adjust which shots to keep or clean up.
Duplicate Photo Identification
Distinguishes exact byte-for-byte duplicates from visually similar copies produced by saving, exporting, or compressing. Review suggested keepers and duplicate versions by group instead of hunting for duplicates across thousands of photos.
Screenshot Content Categorization
Detects text and visual cues on-device to classify screenshots into chats, shopping and payments, web reading, travel receipts, maps, QR codes, code snippets, and more. Screenshots without a confident match stay in other categories rather than receiving inaccurate labels.
Old Screenshots & Outdated Clues
Filter old screenshots past 30 days, 90 days, or a year, with cleanup suggestions for potentially outdated verification codes, logistics tracking, payment confirmations, and temporary notes. Every suggestion requires your review and is never deleted automatically.
Related Screenshot Bundling
Groups sequential captures of chats, web pages, orders, or maps into related screenshot threads, cutting down on opening and checking images one by one. Browse as a full set or adjust selections individually.
Photo Quality Checks
Gathers photos that may be blurry, have closed eyes, severe over- or underexposure, or abnormal face capture quality in one place. Quality flags point out technical flaws without judging appearances, expressions, or personal sentimental value.
Large File Prioritization
View large videos and photos ranked by storage size, preview them, and add candidates to the cleanup queue. Tackling high-impact storage hogs first makes it easy to decide what is worth keeping and what can free up space.
Flexible Review Modes
Multi-select in grids, compare similar photos group by group, or use swipes and tap buttons to mark keep or clean. Undo previous steps at any time; markings persist across views so you can organize at your own pace.
Cleanup Queue & Double Confirmation
All items slated for deletion flow into a central cleanup queue displaying the total count and estimated reclaimed storage. Review and remove items before executing; deletion requires both in-app and system confirmations, and deleted items move safely to the system "Recently Deleted".
Incremental Scanning & Local Cache
Retains local analysis results after the first scan, only processing new, modified, or deleted items on subsequent launches. Scan progress and finished results are cached locally; you can inspect or clear the analysis cache in Settings without affecting original photos.
In depth
The real bottleneck of photo cleaning is constant hesitation
As photo libraries grow, cleanup rarely actually begins. Similar burst shots demand endless comparisons, temporary notifications and receipts clutter screenshots, and bulky videos lie buried deep in your camera roll timeline. Faced with tens of thousands of items, the hardest part is not tapping delete—it is knowing what can go and what is still worth saving.
LumiSweep breaks these choices into manageable micro-tasks: discover clues by content type, gather related items together, and provide technical quality recommendations alongside file sizes. You never have to accept an automated “best photo” verdict; you simply make the final call based on your own photos and memories.
From scan to cleanup, pause and verify at every step
A cleanup session follows a structured, transparent sequence:
- Authorize and Scan: Choose full or limited photo access, indexing and analyzing content locally on your device;
- Review by Category: Browse similar photos, duplicates, screenshots, quality checks, and large files with recommendations to save time;
- Adjust Your Choices: Use grids, multi-selection, comparisons, swipe gestures, or buttons to mark keep or clean, undoing steps anytime;
- Add to Cleanup Queue: Review the total selected count and estimated reclaimed space in one place, removing any accidental additions;
- Confirm and Clean: Free users can decide whether to unlock Pro here, followed by explicit in-app and system confirmation prompts.
Scanning, suggestions, and markings never alter your system photo library until you explicitly execute the final cleanup.
Screenshots organized by context, not just by year
Screenshots usually capture short-lived tasks: a login code, an order receipt, a chat snippet, a map, or a boarding pass. Once the moment passes, they linger in your gallery. LumiSweep recognizes screenshot text and visual cues locally, offering multiple ways to clean them up by content category, age, expiration suggestions, and related sets.
| Cleanup Entry | Best for | What You Can Do |
|---|---|---|
| Content Categories | Chats, shopping, web pages, receipts, maps, QR codes, etc. | Review by purpose in batches |
| Old Screenshots | Screenshots older than 30 days, 90 days, or 1 year | Start from older, forgotten items |
| Outdated Clues | Verification codes, logistics tracking, and payment receipts | Review the rationale and decide |
| Related Screenshots | Multi-part chats, long articles, multi-step order screens | Compare sets and adjust frame by frame |
Screenshots that cannot be categorized with high confidence remain in other categories. All OCR and categorization results are used solely for cleanup and never sent to a server.
Local processing is both our product boundary and operating model
LumiSweep does not require an account, builds no cloud photo profiles, and never transmits your photos to remote services for analysis. Your photos, thumbnails, OCR text, recommendations, and cleanup selections remain strictly on your device, with core analysis and review fully functional offline.
- Local Analysis: Similarity detection, deduplication, OCR, face checks, and quality analysis run entirely on your device;
- Local Storage: Analysis cache and cleanup queue reside inside the app sandbox, and you can clear the cache to re-analyze anytime;
- Zero Tracking: No third-party ad SDKs, behavioral analytics, or tracking libraries;
- Export Only on Demand: Diagnostic logs stay local and only leave the app if you deliberately export them via the system share sheet;
- Store Handles Purchases: Pro purchases and restorations are processed securely by Apple; the app never accesses your payment details.

FAQ
Does LumiSweep upload my photos to the cloud?
No. Similar photo detection, duplicate matching, screenshot text recognition, quality inspection, and categorization all happen entirely on your device. The app requires no account, never uploads photos, thumbnails, or analysis results, and contains no ad trackers or behavioral analytics.
Does LumiSweep delete photos automatically?
No. Scanning, suggestions, and review markings never delete photos on their own. Selected items are only moved to the system "Recently Deleted" album after you confirm adding them to the cleanup queue, tap clean, and pass both in-app and system confirmation prompts.
Is the recommended photo always the most suitable one?
Recommendations are based strictly on technical metrics like sharpness, exposure, and facial state; they cannot evaluate personal sentimental value. You can override suggestions at any time and choose whichever frame you want to keep or delete.
Can free users see the scan results first?
Yes. You can scan for free, view complete results, compare photos, adjust selections, and build a cleanup queue. Pro is only required when executing the final cleanup. Pro is a one-time purchase with pricing displayed on the App Store at launch.
Can I use LumiSweep with limited photo library access?
Yes. LumiSweep only analyzes the photos you grant permission to access, with convenient prompts to expand access at any time. For a full cleanup of your library, full photo library access is required; permissions can also be adjusted anytime in iOS Settings.
Can I recover photos after deleting them?
Items removed through the system deletion process go to the "Recently Deleted" album, where you can view and recover them according to system rules. Before cleaning, LumiSweep displays the item count, storage size, and recovery notes for a final check.
Which devices and system languages are supported?
The app is currently engineered for iPhone and iPad running iOS 18 or iPadOS 18 and later. The interface is available in English and Simplified Chinese. Screenshot OCR language is decoupled from the UI language; it detects automatically and can also be adjusted in Settings.
Is LumiSweep available for download right now?
LumiSweep is currently in development and does not yet have a public App Store download link. This page outlines product capabilities, workflows, and privacy principles. Official availability and download details will be updated upon release.
