Cardio Analytics Features

Complete cardiovascular health tracking with personalized dashboard, medication adherence, evidence-based alerts, and privacy by design

Personalized Dashboard

Track all 11 cardiovascular and mobility metrics in one unified view. See trends, compare against guideline ranges, and monitor changes at a glance.

  • Resting and walking heart rate - Monitor cardiovascular status with normal range indicators (60-100 bpm)
  • Blood pressure tracking - AHA category bands (Normal <120/80, Elevated, Stage 1, Stage 2)
  • Heart rate variability (HRV) - SDNN and RMSSD metrics for stress and health assessment
  • Oxygen saturation (SpO₂) - Track respiratory health with hypoxemia alerts (<90%)
  • Weight and BMI - Monitor body composition with healthy range indicators (18.5-24.9 kg/m²)
  • ECG classifications - Store Apple Watch ECG recordings and AF episode tracking
  • VO₂ Max - Cardio fitness trends and mortality risk marker
  • Walking speed - The "sixth vital sign" for functional capacity (<0.8 m/s risk threshold)
  • Walking asymmetry - Gait balance and fall risk assessment
  • Stair ascent speed - Functional capacity and leg power indicator

Personalized thresholds: Adjust guideline ranges based on your clinician's recommendations.

Medication Adherence & Correlations

Track medication doses and visualize how they relate to your cardiovascular metrics.

  • Manual dose logging - Record medication intake with timestamps
  • HealthKit Medications sync - Automatically import medication records from Apple Health
  • Adherence rate calculation - Track how consistently you take prescribed medications
  • Correlation visualizations - See how medications affect your BP, heart rate, HRV, and weight
  • Trend analysis - Identify patterns between medication adherence and health outcomes

📋 Share medication adherence reports with your clinician to optimize treatment plans.

Evidence-Based Alerts

Intelligent alerts based on respected clinical guidelines and peer-reviewed research.

  • AHA blood pressure categories - Alerts for Elevated (120-129/<80), Stage 1 (130-139 or 80-89), Stage 2 (≥140 or ≥90)
  • Mayo Clinic heart rate thresholds - Bradycardia (<60 bpm) and tachycardia (>100 bpm) detection
  • SpO₂ hypoxemia alerts - Warnings for sustained values <90% (Mayo Clinic guidelines)
  • Cleveland Clinic HRV research - Low HRV warnings relative to your baseline
  • Customizable thresholds - Adjust all alert thresholds based on your clinician's recommendations

⚠️ Not a medical device: Cardio Analytics does not diagnose or treat conditions. Always consult a qualified clinician.

Symptom & Care Hub

Comprehensive health tracking beyond metrics. Log symptoms, track care goals, and manage medical appointments.

  • Symptom logging - Record symptoms with severity ratings and timestamps
  • Care goal tracking - Set and monitor health objectives (e.g., "Lower BP to <130/80")
  • Medical appointment manager - Track doctor visits and follow-ups
  • Professional exports - Generate PDF or CSV reports for your clinician
  • Complete health history - All metrics, medications, symptoms, and goals in one document

📄 Export professional reports to share with your healthcare team for better-informed clinical decisions.

Privacy by Design

Your cardiovascular data stays on your device. You control what to share and with whom.

  • Granular HealthKit authorization - Choose exactly which data types to share
  • 100% local storage - All data processed and stored on your iPhone
  • No cloud servers - No external data transfers, no accounts required
  • No tracking or analytics - We don't collect usage data or personal information
