Getting started
Connect your tracker via USB or WiFi. Green light means you're good.

Run through a quick calibration so Babble learns your face. Takes about a minute.

The App
A modern desktop app built with Avalonia. Manage cameras, flash firmware, calibrate tracking, and connect to your favorite VR platforms — all from one clean interface.
