Gemma 2 On-Device Athletic Coach
Private conversational AI delivering biomechanical form cues, nutritional adjustments, and CNS recovery guidance. Runs 100% locally with live token streaming.
Architected for Athletes Who Value Privacy.
Every algorithm, model inference, and biometric calculation happens on your hardware. Zero cloud dependencies, zero data brokerage.
100% On-Device Gemma 2 Coach
ZeroCoach executes quantized Gemma 2 models directly on your smartphone via llama.rn and native llama.cpp. Dual personas (Strict vs. Comfort) auto-regulate their cues based on your live recovery metrics and remaining nutrition budgets.
Smart Nutrition & NutriSight
Snap a food plate for multimodal decomposition using Gemini 3.8 Flash, or point your camera at nutrition fact labels with Open Food Facts NutriSight token extractors. Includes USDA whole foods and 11 micronutrient RDA bio-gauges.
RepDB Workout Engine
Access 643 exercises from the verified RepDB repository with kinetic start and peak pose imagery. Dynamically adjust volume to your readiness, skip or swap movements on the fly, and review past or future training splits with dedicated calendar date navigation.
Unified Athletic Performance Analytics
Connect directly on-device with Android Health Connect and Apple HealthKit to unify HRV, resting heart rate, sleep architecture, and burn across Garmin, Apple Watch, Whoop, Oura, Samsung, and Pixel wearables. Generates a daily 0–100 composite score with 7D, 14D, and 30D trendlines.
ZeroCoach vs. The Cloud Paradigm.
Why running AI models on your mobile silicon changes the game for athletic training and personal health privacy.
| Capability | ZEROCOACH (On-Device) | Typical Cloud Fitness Apps |
