Similars in Photos app groups latest 500 photos of the Photo Gallery based on their visual similarity, and displays them as Similarity Groups.
Visual similarity means that content is treated only mathematically, objects on the image aren't recognized and cannot be named.
App requires access to Photo Gallery (Photos) to work, please grant access in mobile device Settings or tapping respective request in the app.

The best use case for Similars in Photos is to use it after taking a lot of photos during several days, passing the same routes - then there could be similar photos of the same locations in random places of a Photo Gallery, that makes them harder to detect and compare.

How to use Similars in Photos:
"Config" (gear icon on the left of main Title) leads into Configuration View, where user defines the level of similarity using the "How Similar" slider.The bigger value is, the higher demand is for visual similarity:  - 100 means photos are literally duplicates of each other, - 0 means all 500 photos can be found similar, - this is why it is recommended to use values 70-100, and go below 70 only for fun.
Note: "How Similar" doesn't require recalculation of visual scenes of the photos, so pressing "Sync" just re-groups previously processed photos according to new "How Similar" level.

"Meaning of Similarity" parameter on the "Config" screen can be "WIDER" or "PRECISE". "PRECISE" increases demand for visual similarity. "WIDER" is more tolerant to small changes of the visual scene. It means that when "WIDER" is selected, the wider range of deviations on visual scene still be treated as similar.
Note: After user changes "Meaning of Similarity" - previous processing results will be ignored, and after pressing "Sync" all photos will be processed from the scratch.

"Start" button starts photos processing:
- Processing of 500 latest photos will start.
- Please, do not close the application while it is processing. Processing of all 500 images in "Fast Process" mode (default) can take up to 10 minutes based on the parameters of your device.
- Processing can be stopped by pressing the "Stop" button. Then user can press Sync and app will continue processing from photo where it stopped.

"Sync" button on the right of the main Title starts the syncronisation process: 
- If nothing changed in "Config", and the previous run was inte
