Recently, there has been a rise in virtual YouTubers, or “VTubers,” in Japan — the use of motion-sensing technology to turn an anime character into a person’s online alter ego. To do this, though, involves a bit of setup, including face-recognition software and, if you want to move your arms and legs around, a motion capture system.

Xpression: 4D Face, though, is making the option of borrowing someone’s face available to anyone with an iPhone 6 or above. Developed by the creators of EmbodyMe, an app available on Steam and Oculus VR that can animate avatars via the user’s movements, Xpression can animate video clips, photos and pictures on the iPhone. It replaces the expression of the source face in real time with the facial movements of the user via the phone camera.
