A rhythm game that uses the iPad's camera for hand gesture recognition. Built it because I kept snapping my fingers to music. Won Apple's WWDC23 Swift Student Challenge — 1 of 350 winners worldwide.

A voice-first mental wellness app running a 4B parameter LLM on your phone via llama.cpp. Reads your emotions from your voice (Wave2Vec → CoreML), pulls context from HealthKit, and does on-device RAG — no network requests, nothing leaves your phone.
