## Description

MosaicPhotos brings your on-device photos and your Dropbox photos together in one fast, private viewer, with photo search that runs entirely on your iPhone.

EVERYTHING IN ONE PLACE
- Browse your device library and Dropbox together in a single timeline, or each on its own (All / Photos / Cloud).
- A fast, zoomable grid with a scrubber for jumping across years of photos in seconds.
- Your device albums, plus automatic albums by trip (time and place) and by Dropbox folder.
- Places: photos grouped by city, resolved completely offline.
- A filter bar on every view: show only favorites, or only device or cloud photos.

FIND PHOTOS BY DESCRIBING THEM
- Create AI albums with a plain sentence in your own language: "the kids at the beach last summer" or "Kyoto in autumn, no screenshots".
- The app understands dates, places, people's names, and what is actually in the picture.
- While you type, suggestion chips offer people, places, frequent subjects and dates from your own library, and a live preview shows how your words were understood and how many photos match.
- AI albums stay alive: as new photos are indexed, matching ones are added automatically.

PEOPLE
- On-device face recognition groups photos by person, across both device and Dropbox photos.
- Name people, merge duplicates, choose a key photo, and use names directly in AI albums ("Taro and Hanako").

TAGS AND AI DESCRIPTIONS
- Photos automatically receive scene keywords you can see on the info panel.
- Favorite photos also get a short AI-written description.
- Check progress anytime in Settings under AI Analysis, and start a session on demand while charging.

PRIVATE BY DESIGN
- All AI runs entirely on your iPhone. Photos, faces, tags and search queries never leave your device.
- No account, no ads, no tracking, no third-party SDKs.
- Dropbox is optional and connects directly and securely to your own account.

CONSIDERATE OF BATTERY AND PERFORMANCE
- Heavy AI work runs only while your iPhone is charging, on Wi-Fi and not in use (adjustable in five levels), so browsing always stays fast.

OPTIONAL BACKUP
- Back up device photos to your own Dropbox, organized automatically.

MosaicPhotos requires iOS 26 or later. Dropbox features require a Dropbox account.
