iFacialMocap is four separate apps, not one, by its own account

The setup

iFacialMocap, published by Japan-based DevelopW LLC, is one of the more widely used bridges between an iPhone's TrueDepth camera and desktop 3D software. The developer's own site states plainly what the app does: 'iFacialMocap is an app that captures facial movements with an iPhone equipped with FaceID or Webcam. This app sends the captured motion in real time to 3DCG software such as Maya, Unity, Blender, 3dsMax, Unreal Engine on PC.' This is a living-document entry describing the software as currently documented and sold.

What the documents show

The developer's structured product listing states the paid iOS app costs '$7.99.' The site's own download page documents a more detailed lineup than the homepage alone suggests: two iOS apps, a free ad-supported 'iFacialMocapTrial' and the paid, ad-free 'iFacialMocap,' both reading the iPhone's FaceID camera; and two desktop pieces, a free official receiver called 'iFacialMocap to Software' that relays data to Maya, Blender, Unity, 3dsMax, and Unreal Engine, and a separate paid Windows application, 'iFacialMocap Powered by NVIDIA Broadcast,' which the page states performs 'highly accurate face tracking using only a regular webcam, without the need for an iPhone.'

The craft

The documented split between a phone app and a desktop receiver reflects how most iPhone-based VTuber rigs are actually built: the phone does the sensing, propped on a stand facing the performer, while a separate PC runs the avatar software the phone cannot run itself. The download page notes that VRM-related and most third-party collaboration software can 'communicate directly with the iOS app,' meaning the official desktop receiver is only needed for the specific 3DCG packages it lists by name, not every destination application.

Keeping the creator in control

Offering a free, ad-supported iOS app alongside a paid, ad-free one, both documented as functionally equivalent, gives a creator a genuine no-cost path into iPhone-based tracking rather than a crippled trial - a distinction worth noting given how much VTuber setup advice assumes paid hardware is required. The separate NVIDIA Broadcast-powered application, priced apart from the core app and requiring no iPhone at all, is documented as its own product with its own trial period, not a bundled feature of the main app.

• Does the target 3D software appear on the developer's own list of programs the desktop receiver bridges to?
• Is the free, ad-supported iOS app a viable long-term option, or does the ad-free paid version justify its cost for regular streaming?
• For a creator without a compatible iPhone, does the separate webcam-only application meet the same tracking need?

The developer's own site is unusually specific about which of its four applications does what, a distinction worth reading closely before assuming 'iFacialMocap' refers to a single piece of software.
