"Face Story" is a free iPhone app developed by NIU LIXUAN under the Education & Reference category. This app allows users to turn themselves, their friends, or even their pets into anyone they want by automatically detecting human faces and morphing them with ease.

The app's main feature is its intelligent face feature extraction that makes it easy for users to create their own growing up movie from a baby. Users can preview and play the final effects in real-time and share their face story video on Facebook, Instagram, Vine, and other social media platforms.

Overall, "Face Story" is a fun and entertaining app that lets users create unique and hilarious videos by morphing their faces. However, it should be noted that the app may not work well with certain face types or lighting conditions.
