Simple PhotoMap lets you browse the photos on your phone by both the date and the place they were taken. It scans the photo folders on your device and shows your pictures in two views: a gallery and a map.

Features:

- Gallery (organized by date)
- Photos are automatically sorted by shooting date and listed with month/year group headers.
- A date indicator appears while scrolling so you always know where you are in the timeline.

- Map view (MapLibre)
- Photos are placed on the map where they were taken (powered by MapLibre).
- Several photos taken at the same place appear as a cluster with a representative thumbnail and a count badge.
- Tapping a cluster opens the photos for that place from the bottom of the screen (with a place-name title).

- EXIF details
- Check shooting info such as camera, lens, focal length, F-number, ISO sensitivity, shutter speed, resolution, location, and GPS coordinates.
- You can also keep the shooting info overlaid on top of the full-screen photo.

- Full-screen viewer
- Pinch to zoom in/out, and swipe left/right to switch between photos.

- Filters and sorting
- Filter photos by camera, lens, focal length, location, and shooting date.
- Switching the sort order is also supported.

- Folder management and scanning
- Register and manage multiple folders to scan.
- The first run performs a full scan; after that, incremental scans only analyze new or updated photos.
- Photos can be deleted even while scanning.

- Thumbnail cache
- 300px WebP thumbnails are generated and cached automatically for a comfortable gallery.

- Photo deletion
- Delete photos one by one, or long-press to select several and delete them at once.

- Place names
- Reverse geocoding for place names can be turned on or off in the settings.

- Others
- A calm dark-theme design.
- Available in English and Japanese.
- Open source licenses are displayed in the app.

About privacy:

- All photos are processed on your device, and no photo data itself is ever sent off the device.
- Only when fetching a place name (reverse geocoding) is the location (latitude/longitude) sent to a server. Turning place-name lookup off stops any location transmission.
