## Frequently asked questions

### What is Ness?

The Ness app is an AI health coach for iPhone and Apple Watch that turns your Apple Health data into daily Health, Sleep, Recovery, Strain, Stress, and Energy Level scores. It pairs those scores with an AI health chat, AI nutrition tracking, and long-term trend charts so you can understand when to train, recover, or adjust your habits.

### What is the Ness coach?

The Ness coach is the AI health coach built into the Ness app. It reads your Apple Health data — sleep, HRV, heart rate, workouts, and nutrition — and turns it into daily guidance grounded in your own numbers, not generic advice. You can ask the Ness coach why your Recovery Score dropped, what to eat after a hard training day, or how your stress has trended this month, and it answers from your actual data, with web search for anything outside it.
