MotionPortrait™ is a free lifestyle app developed by MotionPortrait Inc for iPhone users. It can transform any portrait photo into a moving 3D avatar that repeats your every word. The app is easy to navigate and use, and it provides users with a unique experience of seeing themselves in a 3D animated version.

To use the app, you can either take a portrait photo or pick one from your photo library, and the face will automatically start moving in 3D. You can then talk to it, and it will repeat your every word. Furthermore, you can try fun hairstyles, glasses, masks, and beards, and apply them to your animated 3D avatar. You can even record your moving 3D avatar as a movie and share it with your friends via email, Facebook, and Twitter. You can also upload your new look to Twitter and Facebook and use it as your Twitter profile icon.

The app assures its users that it does not collect any personal data. The avatar is created without uploading the photo to any web server, and the app does not save or upload the avatar data without the user's operation. Overall, MotionPortrait™ is a fun and entertaining app that provides users with a unique and enjoyable experience of seeing themselves as a 3D avatar.
