Ness: AI Health Coach

Ness is an AI health coach for iPhone and Apple Watch, built on your Apple Health data. Sleep better. Train smarter. Build muscle. Recover fully. Ness turns your health data into a daily plan you can act on: when to push, when to rest, what to eat, and which habits are paying off. Set goals that track themselves, log workouts and meals in seconds, and watch your biological age and pace of aging improve. FEATURES AI Health Coach: Ask anything in chat and get answers grounded in your data, with interactive cards for charts, day plans, and one-tap food logging. Connect your calendar and Ness plans around your schedule. Review what Ness remembers in Settings. Daily Insight and Morning Brief: Wake up to a personalized brief built on last night's sleep, plus one daily insight that connects sleep, recovery, strain, nutrition, and your journal into practical next steps. Sleep: Understand your sleep stages, efficiency, HRV, resting heart rate, respiratory rate, blood oxygen, and wrist temperature. See your circadian energy curve, caffeine cutoff, and best time to wind down. Training: Follow daily goals, training load, and per-muscle load so you train at the right intensity. Log workouts with an exercise library, set-by-set tracking, and Apple Health sync, or let Ness build your plan. Nutrition: Log meals with a photo, barcode, voice, or text search and get calories, macros, and micronutrients. Adaptive calories update your targets based on your weigh-ins and food logs. Habits and Goals: Journal daily habits and custom entries, then compare them with your health metrics. Set goals that track themselves from Apple Health and your journal, and follow streaks from Home. Biological Age: See your biological age, pace of aging, 30-day change, and the factors driving it.
