Holiwell: AI Health Agent
Denis Rossiev
Holiwell is a health agent that actually knows you. It connects every signal your body sends — sleep, training, food, supplements, bloodwork, body composition, your cycle — and tells you what to do about it. Most health apps hand you charts and leave you guessing. Holiwell works the other way around: at the center is an agent you talk to. It sees your full context, draws the conclusions itself, and acts — logging, adjusting targets, building workouts. The dashboards are there too, but the conversation is the product. One app instead of ten. Your cycle isn't a separate app. Neither are your labs, your supplements, or your measurements — and because everything is calculated together, a dropping ferritin is read alongside your rising running volume and your poor sleep. FEATURES. Health Agent: Ask anything in plain language — text, voice or a photo. Every chat already sees a live slice of 50+ metrics, and the agent pulls up whatever else it needs. No re-explaining yourself, no exports, no starting from scratch. Effortless Logging: Describe a meal or photograph your plate and get a full breakdown by dish — calories, macros, fiber, sugar, protein quality. Same for supplements, workouts, weight, measurements, even a photo of a bioimpedance printout. Nothing is written without your confirmation, and everything is undoable. Adaptive Calorie Target: Your calorie and macro targets are calibrated against your real metabolism — actual intake, actual expenditure, actual weight trend — instead of a textbook formula that is the same for everyone. Recovery Score: Sleep, HRV, resting heart rate, temperature and yesterday's load, compared to your own baseline rather than a population average. Know whether to push today or back off. Sleep Score: One hypnogram stitched from every source, a 0-100 score, sleep debt, time to fall asleep, wake-ups, and overnight vitals measured inside your sleep window. Strain & Training Load: TRIMP from your raw heart-rate series, acute and chronic load, ACWR balance, heart-rate zones, VO2max, running splits and heart-rate recovery. Train hard without walking into overtraining you'd notice a week late. Nutrition Score: Weekly diet quality from three parts — hitting calories, hitting macros, and the quality of the food itself. Body: Weight with a smoothed trend, lean mass, body fat, circumferences from neck to calves, and a full BIA panel — visceral fat, water, phase angle, measured BMR. Bloodwork: Send a lab result any way you have it — photo, PDF, scan, file, or numbers typed into the chat. Holiwell returns a biomarker panel with your lab's reference ranges, keeps the original attached, and unifies results from different labs into one history in consistent units. The agent comments on it in the context of everything else. Biological Age: How old your body reads, with a breakdown of what each metric contributes in years. Cycle: Phases, predictions and confirmations — and the phase is a factor in the rest of the app, from training advice to your calorie target. Memory & Reminders: Allergies, diagnoses, findings from medical reports, genetics — remembered for good and present in every conversation. The agent sets and sends its own reminders. Apple Health: Holiwell reads your activity, workouts, sleep, heart and body data from Apple Health, and writes workouts and measurements back so the rest of your ecosystem sees them. Works Without a Wearable: A tracker changes how much is automatic, not what you can do. Anything a sensor doesn't provide, you add with one message — and every calculation degrades gracefully instead of refusing to work. Widgets: Recovery, strain, steps, nutrition and cycle on your Home and Lock Screen. Holiwell is not a medical device and does not provide medical advice, diagnosis, or treatment. Always consult your doctor in addition to using this app and before making any medical decisions. Terms of Service: https://holiwell.ai/terms Privacy Policy: https://holiwell.ai/privacy
