Cardia Sleep is the only consumer sleep app focused on hemodynamic analysis — tracking how your heart rate dips during sleep, a clinically significant indicator of cardiovascular health that no other app surfaces. WHAT MAKES CARDIA SLEEP DIFFERENT While other sleep apps focus on wake-up alarms and generic quality scores, Cardia Sleep analyzes your nocturnal heart rate dipping pattern — the measurement cardiologists use to identify "Non-Dipping Hypertension," a condition linked to increased cardiovascular risk. YOUR NIGHTLY DIP DASHBOARD • Dip Percentage — how much your heart rate drops from day to night • Color-coded status — Dipper (healthy), Non-Dipper (at risk), or Reverse Dipper (critical) • Trend tracking — see if your dipping pattern is improving or worsening over time SLEEP SCORE (0–100) A composite score weighted across four clinical dimensions: • Duration — are you sleeping enough? • Deep Sleep — are you getting restorative sleep? • Heart Rate Dipping — is your cardiovascular system recovering? • HRV — is your nervous system properly resetting? SMART FEATURES • Morning Debrief — daily AI-powered summary of last night's sleep • Sleep Debt Tracker — know exactly how many hours you owe your body • 8 Achievement Badges — gamified milestones to build healthy habits • 14-Night Streak Tracking — consistency is key • Bedtime Reminders & Smart Notifications PRO FEATURES • Doctor-Ready PDF Reports — share your 30-day dipping trend with your healthcare provider • AI-Powered Insights (Ask Cardia) — get personalized answers about your sleep data • Unlimited Session History — see all your data, not just the last 7 days • Non-Dipper Streak Alerts — get notified after 3+ consecutive at-risk nights • Advanced Weekly Analytics — duration charts, stage breakdowns, HRV trends • Pro Achievement Badges PART OF THE CARDIA ECOSYSTEM Cardia Sleep works alongside Cardia Steps, Meds, Care, and more — connecting your sleep data to your broader health picture through a shared data layer.
