RabbitBox - Image Organizer 17+‎

RabbitBox is an app for collecting, organizing (tags, duplicate similarity search), and viewing image files.
It collects images from web pages, and manages a large number of images by using powerful tag functions with hierarchical structure, metadata, and high-speed similarity search in a single application.

[Features]
Powerful tag function
- Tags can have parent-child relationships and can be used not only as simple tags but also as folders.
- You can set up aliases for tags, and search for tags even if they are misspelled, such as hiragana, English, and thesaurus.

Collect, organize, and view in one app
- The image management and collection (download) functions are integrated, so tags and metadata can be added and managed seamlessly during collection.

Standalone app
- As images are stored on the device, they can be used even without an Internet connection.
- There is no capacity limit like cloud storage, so you can store as many images as your device allows.
- It is also independent of the camera roll and does not clutter up the Photos app.

Image Stack Groups
- You can easily group multiple images together as if they were a single image file.
- You can group different variations or short cartoon style images together.
