This app is a gallery that allows you to search for all the photos on your phone that feature a certain person. Simply when you open a photo, the app detects the faces in that photo and highlights them with a rectangle. You simply tap the desired rectangle, and the app returns all the photos that feature the person you tapped.

The app requires permission to access your phone's files and notifications. It won't bombard you with notifications; the only one you'll receive is when it finishes indexing the photos on your device. The first time you run the app, it will scan your phone's photos to detect all the faces. This way, when you search through thousands of photos, the results will be instantaneous.
