Another feature of the app is the "How attractive am I" tool, which scans and analyzes your face using the golden face ratio, face shape, face emotions, makeup, hair color, and bald percentage. This feature can be used to determine how pretty or hot you look, rate your look, and provide a beauty score. It also offers a baldness or hair loss test that provides a bald percentage and hair loss percentage.

The app also includes a gray hair scan that uses face analysis to provide color percentage, a makeup detector that can determine whether your friend has put on makeup, and an "Add Quote to selfie" feature that allows you to add different quotes images to your selfie. Additionally, the app offers a "Wanted Poster Frame" and "Prison, Jail Selfie" feature that allows you to make a poster frame from your picture. Finally, the app includes a "Photo Puzzle" game and an "Automatically Create Lipstick Kiss Mark Picture" feature.
