Ness

Ness turns your Apple Health and Apple Watch data into daily Health, Sleep, Recovery, Strain, and Stress scores so you can understand when to train, recover, or adjust your habits.

Built for more than athletes, Ness brings fitness, sleep, recovery, stress, nutrition, and AI health coaching together in one place.

FEATURES

Daily Health Scores: Start each day with Health, Sleep, Recovery, Strain, and Stress scores calculated from sleep, activity, heart rate, HRV, and other Apple Health data.

Personalized AI Insights: Get dedicated AI insights for health, sleep, recovery, strain, and nutrition. Ness summarizes recent patterns and suggests practical next steps. Continue any insight in AI Chat.

AI Health Chat: Chat with an AI health coach grounded in your Ness data. Ask about sleep, recovery, stress, strain, workouts, heart rate, nutrition, and trends. Use voice dictation, attach images, and customize how Ness responds.

AI Nutrition Tracking: Log meals with a photo, voice description, barcode scan, or text search. Ness estimates calories, macros, and micronutrients. Adjust servings, log recent foods again, and follow personalized nutrition targets.

Apple Health Nutrition Sync: Import nutrition from compatible apps through Apple Health and export meals logged in Ness, including supported macros and micronutrients.

Fitness, Recovery, and Target Strain: Review workouts, steps, active calories, heart-rate zones, resting heart rate, heart-rate reserve, and heart-rate recovery. Use Target Strain to balance training with recovery.

Sleep and Recovery Analysis: Explore sleep duration, Deep, REM, and Core sleep, awake time, interruptions, efficiency, HRV, resting heart rate, respiratory rate, blood oxygen, and wrist temperature. Get personalized sleep schedule recommendations when enough history is available.

Metrics and Long-Term Trends: Explore more than 18 health and fitness metrics through interactive charts covering one week to one year. Compare values, averages, and trends over time.

Apple Watch, Widgets, and Complications: View scores and trends in the Ness Apple Watch app. Keep key scores visible through Watch complications, a combined Daily Scores complication, and the Ness Home Screen widget.
