ARKit-based face tracking. Requires a Face ID-compatible iOS device and the $5.99 iFacialMocap app. Tracks 52 ARKit blendshapes, head rotation and head translation.

An alternative to iFacialMocap is FaceMotion3D, which is $14.99 for a permanent license. It has more features than iFacialMocap, but in regard to face tracking for Warudo, the two apps are functionally equivalent.


For best tracking quality, we recommend using an iPhone 12 or newer (iPhone mini also works). Older iPhones may have lower tracking quality.


If your iPhone is not compatible with Face ID, you may still be able to use iFacialMocap / FaceMotion3D if it has an A12 or higher chip and has been updated to iOS 14. However, the tracking quality may be subpar.
