Key Features 1. Smart Medication & Supplement Tracking (The "Rx") Keep your health regimen on schedule with an intuitive medication tracker. Smart Reminders: Custom scheduling, dosage quantities, and frequency configurations. Daily Checklists: A real-time, tap-to-log checklist on your today dashboard keeps you accountable and records precise compliance timestamps. Optimal Timing Windows: Log medication exact times to analyze if you are taking doses in synchronization with your circadian patterns. 2. Circadian-Aligned Habit & Activity Logger Log daily events with single-tap ease using the Quick Activity Grid. Track core variables that dictate sleep quality: caffeine intake, screen time, exercise intensity, stress levels, and light exposure. Time-sensitive logging helps you map out exactly how close to bedtime you are engaging in these activities. 3.

CiRxadian's built-in analysis engine actively correlates your daytime habits and medication times to uncover hidden trends: Caffeine Clearance Windows: Pinpoints how late-day caffeine intake (e.g., after 2:00 PM) reduces your deep sleep phase. Supplement Synergies: Demonstrates the positive impact of evening supplements (like Magnesium Glycinate or Melatonin) on your sleep quality when taken inside optimal windows. Lifestyle Insights: Provides actionable "Circadian AI" scores indicating which habits improve or hinder your rest. 5. Nocturnal Disruption Log Track the exact reasons behind night awakenings. Log nocturnal events like middle-of-the-night waking, ambient environment noise, coughing, or anxiety, to evaluate exactly what is disrupting your restorative sleep cycles. 6. Clinical Digests (PDF Share) Prepare for your next doctor’s visit with professional data export. Generate a comprehensive Sleep & Medication Summary PDF Report detailing compliance rates, sleep statistics, and logged activities.
