https://apps.apple.com/us/app/curaporta/id6785185856Most people guess when their doctor asks about family health history. Curaporta ends the guessing. Curaporta is the 1st health app that connects three things no other app brings together: your symptoms, your Apple Health data, and your family's health history, all in one private, secure place.
Most health apps track one thing. Curaporta connects three:
• Symptoms: log how you feel, in your own words, anytime.
• Device data: Apple Health metrics synced automatically: heart rate, sleep, steps, HRV.
• Family history: connect with biological family members and see anonymized hereditary patterns.
Our AI brings all three together to help you understand patterns in your health that no single source could ever reveal on its own.
