This is the App your front-camera was made for! FaceLock uses state-of-the-art biometric technology to grant you access to the application based only on your face. No tricks, no hidden buttons to press, just scan your face and gain access. Amaze your friends when your phone grants you access but then denies everyone else.
- Real Facial Recognition
- Access granted to authorized face only
- HD Retina Graphics
When you first launch FaceLock, you must train it to recognize your face, training takes less than a minute and only needs to be performed once.
If you want FaceLock to grant access to a different face, you can do so from the settings screen.
* Requires device with front-facing camera
* For optimal recognition, make sure your face is centered, straight and well-lit.
