What is the calibration period?

When you first start your journey, you enter a 14-day Calibration Period. During this time, Kira, your personal AI assistant, works behind the scenes to learn your unique biological rhythms and lifestyle patterns.

What to expect during the first 14 days

Think of this period as an "onboarding" for your body data. Because Kira is building your baseline from scratch, your experience will evolve as the days progress:

• Days 1–4 (Initial Data): You will see limited data in your Sleep and Energy circles. This is normal! Kira is collecting enough data points to ensure your "normal" range is accurate.
• Learning the Metrics: This is the perfect time to explore the app and learn what each metric means.
• Daily Check-ins: Kira will ask you questions about your lifestyle. Please be diligent in answering these! Your input allows Kira to correlate your habits with your heart rate, movement, and sleep data.

💡 Pro Tip: Answering Kira’s questions accurately during these 14 days directly improves the quality of your recommendations and data analysis for the long term.

What happens after Day 14?

Once the calibration period is complete, the app unlocks its full potential. You will transition into a fully personalized experience, including:

• Deep Personalization: Your metrics will be measured against your own established baselines rather than general averages.
• Personalized Home Feed: You will gain access to a new home page feed featuring Kira’s custom recommendations.
• Chronotype Insights: You’ll receive specific advice tailored to your Chronotype (your body’s natural clock), helping you optimize when to sleep, eat, and work.

Does calibration ever end?

While the initial period is 14 days, your body is always changing. To stay accurate, your baselines and metrics automatically re-calibrate every 14 days.

This ensures that as your fitness improves or your lifestyle shifts, your recommendations evolve right along with you.
