The company is building a wearable device that measures and surfaces real-time emotional-state data - think energy, mood, and focus - derived from a proprietary inference model processing over 150 audio and biometric signals. Prototypes are already on users' wrists., * Own the companion iOS app from architecture through to polished, consumer-grade delivery

 * Integrate and surface real-time emotional-state outputs (e.g. energy, mood, focus scores) from the backend inference model into the app experience
