Your health, across time

Free · Designed for iPad. Not verified for macOS.

Chrona is a private health vault that puts your entire medical history at your fingertips — beautifully organized across time. Unlike other health apps, Chrona stores everything locally on your phone. No accounts. No cloud. No data harvesting. Your health data belongs to you and stays on your device. BEAUTIFUL HEALTH TIMELINE See your entire health journey on one scrollable timeline. Lab results, symptoms, doctor visits, vaccines — every health moment organized chronologically with color-coded entries you can tap to explore. LAB RESULTS WITH CHARTS Track any biomarker over time with clear trend lines and normal range overlays. See at a glance whether your cholesterol, vitamin D, glucose, thyroid, or any other marker is improving, stable, or needs attention. SYMPTOM TRACKING Log headaches, fatigue, pain, or any symptom in seconds. See monthly counts, severity trends, and frequency patterns. Discover which days or times your symptoms are most common. BLOOD PRESSURE & VITALS Track blood pressure with automatic category labels (normal, elevated, high). Monitor weight and BMI trends. Log any custom vital sign that matters to you — temperature, heart rate, blood sugar, or anything else. SMART INSIGHTS Chrona detects trends and patterns in your data automatically — all on your device, no internet needed. See when a biomarker is trending up, when symptoms are increasing, or when your blood pressure shifts categories. SCAN YOUR LAB REPORTS Photograph a lab report and let Chrona read the values for you. Review the extracted results, make corrections if needed, and save them to your timeline in seconds instead of typing everything manually. COMPLETE HEALTH VAULT Store vaccine records with certificate photos. Keep track of medications — active and past. Log doctor visits with follow-up reminders. Save medical documents by photographing them. Keep emergency info accessible. DOCTOR-READY PDF EXPORT Generate a clean health summary PDF you can share with your doctor. All your lab trends, vital signs, medications, and recent symptoms in one professional report. ENCRYPTED BACKUP Back up your entire health vault to an encrypted file. Protected by a password you choose. Restore anytime on the same or a new device. Your backup, your key. PRIVACY BY DESIGN No account required. No sign-up wall. No tracking. No ads. No data collection. Everything lives on your device. Chrona works fully offline — your health data never touches a server. Free to use for all core tracking features. Chrona Pro unlocks AI-powered summaries, smart lab report scanning, encrypted backups, and advanced insights. Chrona is not a medical device and does not provide medical advice. Always consult a healthcare professional for medical decisions.
