Voia Tracker

VoiaTracker turns your iPhone into a wireless motion tracker and camera feed for VoiaPreviz, the iPad-based virtual production and pre-visualization app. Mount an iPhone on any camera rig and VoiaPreviz instantly gets a synchronized ARKit pose stream and live video, ready to composite against 3D environments in real time. VoiaTracker is a companion app. It does nothing on its own: it must be paired with VoiaPreviz running on an iPad on the same Wi-Fi network. HOW IT WORKS • Launch VoiaTracker on an iPhone connected to the same Wi-Fi as your iPad. • VoiaTracker automatically discovers VoiaPreviz over the local network. • The iPad assigns each connected phone a color and a camera letter (A, B, C…), so every operator on set knows exactly which tracker belongs to which camera. • ARKit world-tracking data streams continuously to the iPad, while the camera feed is delivered over WebRTC for low-latency previz compositing. DESIGNED FOR VIRTUAL PRODUCTION • Real-time ARKit 6-DoF pose streaming (position, rotation, tracking state, floor anchors). • Live camera video over WebRTC, synchronized with the pose stream. • Multi-tracker support — run several iPhones at once, each identified by color and camera letter. • Full-screen color identification mode with animal icons, readable from across the stage. • Persistent tracker identity — each phone keeps its assignment across restarts. • Local network only. No cloud. No accounts. No internet required. • One-tap export of tracking logs for archival or offline review. ON-SET WORKFLOW 1. Open VoiaPreviz on the iPad and start a session. 2. Launch VoiaTracker on each iPhone rigged to a camera. 3. Grant camera and local network permissions. 4. VoiaPreviz picks up each tracker automatically. 5. Assign cameras from the iPad — the phone shows its assigned letter and color marker instantly. REQUIREMENTS • iPhone with ARKit world-tracking support (iPhone XS or newer recommended). • iOS 18.5 or later. • Wi-Fi connection on the same local network as an iPad running VoiaPreviz. • VoiaPreviz app installed on a compatible iPad. VoiaTracker is built for filmmakers, virtual production crews, VFX supervisors, and previz artists who need reliable, low-cost, wireless on-set tracking without external hardware.

Verdict
The clearest difference is in-app purchases: Voia Tracker at none against Dot3D's 2. Dot3D's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 18.5). On price, update cadence and ads there is nothing between them.
