Health isn't static. It changes little by little with sleep, stress, food, hormones and age. Previva helps you see that movement in your own lab results. UPLOAD YOUR RESULTS Upload the PDF or a photo of your lab report. Previva extracts your biomarkers and explains each one in plain language. Every report is a point in your health story. WHAT CHANGED Compare each marker with your previous measurement: what improved, what stayed the same and what is worth watching. WHERE YOU'RE HEADING See the direction of each body system over time and which tests you're missing for a more complete picture. YOUR PERSONAL RANGE With several reports, Previva works out what is normal for you for each marker, not just the population average. MEASUREMENTS AND APPLE HEALTH Log weight, waist, blood pressure, glucose, temperature and pulse, or connect Apple Health to read steps, sleep, heart rate and more. Your measurements build your usual range. HOW YOU RECOVER After a cold, a trip or a stressful week, see how many days it takes you to get back to your level and what your typical recovery time is. PREVIVA CHAT Ask about your results to an AI assistant that knows your history. You can type, send photos or use your voice. MY CYCLE AND MEDICATIONS Menstrual calendar, basal temperature and medication reminders, in the same place as your lab results. SERVICES IN MEXICO Order lab panels with at-home sample collection and book video consultations with doctors. Start for free. Plus and Premium unlock your full history, the values of your personal range and more features. Subscriptions: payment is charged to your Apple Account at confirmation of purchase.
