## What is PhotoGem?

PhotoGem automatically finds and groups similar photos in your library, helping you keep only the best shots. Browse and compare photos from Apple Photos, NAS drives, and local folders — all in one app.

Automatic Similar Photo Grouping
Detects nearly identical photos using image hashing, histogram analysis, and AI embeddings (MobileCLIP2). Instantly spot burst shots, repeated compositions, and subtle duplicates.

NAS & External Drive Integration
Browse photos directly on Synology, QNAP, Ugreen, and other SMB-compatible NAS devices over your network. Add external drives or local folders to manage all your photos in one place.

Professional Format Support
Supports 15 RAW formats including Sony ARW, Canon CR3/CR2, Nikon NEF, Fujifilm RAF, and Hasselblad 3FR, plus PSD, EXR, and AVIF. Preview large DSLR and mirrorless RAW files instantly.

Photo Map
View photos with GPS data as thumbnail cards on a map. Zoom in to see individual shots at each location.

Storage Analytics
Visualize format-based storage distribution, monthly photo trends, and largest files with interactive charts. Manage your storage efficiently.

Quality Issue Detection
Automatically classify blurry, overexposed, underexposed, and low-contrast photos. Quickly find photos that need cleanup.

Synchronized Zoom Comparison
Place photos side by side and zoom into the same area simultaneously to compare fine details like focus, noise, and expressions.

Simple Cleanup
One tap on Keep Best keeps the highest-quality photo and marks the rest for deletion. Deleted photos can be restored from Recently Deleted.

Privacy First
All analysis runs on-device. Your photos are never sent to external servers.

## Version history (last 5 releases)

### 1.2.3 — 2026-09-07

• Prepared for iOS 27, iPadOS 27 and macOS 27
• Fixed Apple photos without a readable original filename being grouped together as if they shared one
• Added the privacy manifest Apple now expects from every app
• Additional stability fixes

### 1.2.2 — 2026-09-03

• Fixed the merged gallery being built, and saved, without any Apple photos when Photos access had not been granted yet. Matching then had nothing to merge into, and the banner never went away
• Opening the merged gallery now asks for Photos access first
• Granting Photos access while the app is open rebuilds the merged gallery
• Additional stability fixes

### 1.2.1 — 2026-09-02

• The merged gallery opens instantly. It shows the last scan first and quietly rescans behind it, so the "Merging your sources" screen appears only the first time
• Thumbnails are sharper: a quick preview is replaced by the full-quality thumbnail, and photos stored only in iCloud are fetched and upgraded in the background
• Fixed a photo that exists once being shown as "4 copies" in the merged gallery. Within one source only identical files merge now, and Apple photos are never merged with each other by image comparison
• Removed the "×2" count from thumbnails. Badges show where a photo lives; the delete confirmation is where file counts belong
• The "Match Photos" banner no longer comes back after you tap it or choose "Not Now". It only returns when noticeably more photos are waiting
• On iPhone the screen stays awake while matching runs, so it finishes instead of stopping when the phone locks
• Fixed different photos being merged into one across several matching runs
• Fixed a restored NAS copy staying invisible after its Apple copy could not be restored
• Deleting a photo that spans two sources in the merged gallery now confirms the file count first
• "Delete from this source only" in the viewer now moves on to the next photo
• Changing "Holds backups of Apple Photos" in the source editor now takes effect immediately
• Fixed a rare crash while scrolling during a matching run
• Translated the remaining English strings in Korean mode (filters, the merge screen, the undated section)
• Additional stability fixes
• Note: the matching rule changed, so the first launch asks you to match once more. Photos already read are kept, so it is quick

### 1.2.0 — 2026-08-31

- Korean support: the app is fully translated. Choose Korean or English in Settings, or leave it to follow your system language
- Guided tour on first launch: a short walkthrough points out the main features, with its own guidance the first time you open Similar Photos and Compare
- More accurate photo matching: substantially fewer cases of different photos being merged as the same one, especially among burst shots and screenshots
- Photos that exist once per source no longer appear in Similar Photos — the app no longer suggests deleting your backup
- Source badges now appear in Similar Photos and Compare, so you can tell an Apple photo from a NAS one at a glance
- Recently Deleted: deleted photos stay listed after you quit and reopen the app, and now show their thumbnails
- When a delete would reach a source you are not looking at, PhotoGem asks first and offers "Delete from this source only"
- Fixed NAS photos failing to delete
- Added help text explaining what Cross-Source Sync does
- Additional stability fixes

### 1.1.1 — 2026-08-30

- All Sources gallery: Apple Photos, NAS, and local folders in one gallery — every photo carries a source badge, and identical photos from multiple sources collapse into a single card
- Match by Image: finds the same photo across sources by comparing pixels directly, even when filenames or dates differ. Runs in the background with progress and ETA, is safe to stop anytime, and banks its results so the next run finishes in minutes
- Mirrored delete: deleting a merged photo removes it from every linked source
- Delete straight from the photo viewer: trash a photo while viewing it full screen. In the All Sources gallery this removes every linked copy
- Photo deletion in the iPhone and iPad galleries
- Returning from a photo keeps your place in the grid instead of jumping to the top
- Video playback stability: fixed a crash on playback and an info card that covered the player controls
- Fixed Apple Photos intermittently appearing empty: permission state is now detected automatically with recovery guidance
- NAS cache cap (2 GB): disk usage is bounded, with cache visibility in Settings
- Greatly improved similar-photo detection recall, plus nearly 100 stability and performance fixes
