Turn your Android phone into a dedicated VTuber face tracker.

VTube AR FaceSync tracks your facial expressions on Android and sends real-time facial tracking data to compatible VTuber software on your PC.

Works with more avatars

Choose the compatibility mode that matches your model:

• Standard VRM / VRoid — designed for normal VRoid Studio and VRM avatars using standard VRM expressions.
• ARKit / Perfect Sync — full ARKit-compatible blendshape output for avatars prepared with Perfect Sync facial shapes.

That means beginners can start with a normal VRoid/VRM avatar, while advanced creators can use richer Perfect Sync facial tracking when their model supports it.

Compatible VTuber workflows

FaceSync is designed for VMC-based workflows including:

• Warudo
• VSeeFace
• VNyan
• Other compatible VMC receivers

Expressive facial tracking

Track head movement, blinks, squints, eyes wide, smiles, frowns, brows, mouth movement, cheek puff, tongue out, and other supported expressions.

Available expression detail depends on the avatar. Standard VRM/VRoid models use their built-in VRM expressions. Perfect Sync models can use the fuller ARKit-compatible blendshape set.

Built for streaming

Run facial tracking on your Android phone while your PC focuses on your avatar software, OBS, games, and streaming tools.
