About
Ness is an AI health coach for iPhone and Apple Watch that turns your Apple Health data into daily Health, Sleep, Recovery, Strain, and Stress scores so you can understand when to train, recover, or adjust your habits.
Daily scores and insights. Health, Sleep, Recovery, Strain, and Stress scores from sleep, activity, heart rate, HRV, and other Apple Health data, with AI insights that summarize patterns and suggest next steps.
AI health chat. Ask about your sleep, recovery, stress, strain, workouts, heart rate, nutrition, and trends. Ness is grounded in your own data and supports voice dictation and image attachments.
AI nutrition tracking. Log meals with a photo, voice description, barcode scan, or text search. Ness estimates calories, macros, and micronutrients, with two-way Apple Health sync.
Fitness, recovery, and target strain. Review workouts, heart-rate zones, resting heart rate, and recovery. Sleep analysis covers duration, Deep/REM/Core sleep, efficiency, HRV, respiratory rate, blood oxygen, and wrist temperature.
Apple Watch, widgets, and complications. View scores from your wrist, keep key scores on your watch face, and glance at the Home Screen widget. Lock Screen controls start food logging without opening the app.
Privacy. Ness does not sell or train on personal or health data. AI features use a Zero Data Retention policy. You control Apple Health permissions. Health Data stays on your device and doesn't touch our servers.
