Sleep Score Chart

Our sleep score is a comprehensive metric derived from analyzing four primary sleep states: REM sleep, deep sleep, light sleep, and awake periods. Each of these states contributes differently to your overall sleep quality.

  • REM Sleep: This stage is associated with vivid dreams and cognitive restoration. It's a crucial phase for memory consolidation and emotional regulation during sleep.

  • Deep Sleep: Known as restorative sleep, this stage is characterized by slow brain waves. It's essential for physical recovery, immune function, and feeling refreshed upon waking.

  • Light Sleep: A transitional stage between deep sleep and wakefulness. It typically constitutes a significant portion of total sleep time and plays a role in processing memories and restoration.

  • Awake Sleep: Periods of wakefulness during the night, which might disrupt the continuity of sleep and impact overall sleep quality.

Our algorithm evaluates the duration and quality of each sleep state, considering factors like duration, interruptions, and transitions between these states. By quantifying and analyzing these parameters, we compute a sleep score that reflects the overall quality of your sleep. This score serves as a valuable indicator to help you understand and improve your sleep patterns over time.

The steps chart offers a visual representation of your daily activity by displaying the number of steps taken throughout the day. It serves as a straightforward indicator of your movement levels and progress toward achieving your activity goal.

This chart dynamically sets your daily step goal based on the average number of steps you've walked over the past 30 days, adapting to your recent activity levels. By comparing your current day's step count to this personalized goal, it provides immediate feedback on whether you've met or surpassed your target, encouraging you to maintain an active lifestyle.

In essence, the steps chart is a simple yet effective tool that encourages consistent physical activity. It aims to motivate incremental improvements in your daily step count, promoting a healthier and more active routine.

Heart Rate Chart

Our heart rate chart illustrates your heart's activity over the last 24 hours, presenting your heart rate measured in beats per minute (BPM) every 5 minutes. It categorizes your heart rate into five distinct zones, providing a comprehensive understanding of your activity levels and exertion throughout the day.

Zones Overview:

  1. Active Recovery: Representing the lowest range of heart rates, this zone signifies calmness and relaxation during periods of rest or low-intensity activities.

  2. Endurance: A moderate intensity zone where the body starts using fat as a primary energy source, beneficial for endurance and weight management.

  3. Tempo: This zone indicates a moderate-to-high intensity level, ideal for improving cardiovascular fitness and overall endurance.

  4. Threshold: A higher intensity zone for challenging workouts or activities, helping enhance athletic performance and pushing physical limits.

  5. VO2 Max: The highest intensity zone, representing maximum effort during intense exercise or high-intensity intervals, crucial for building strength and pushing boundaries.

By analyzing the distribution of your heart rate across these five zones, you gain insights into the intensity levels of your daily activities and workouts. Monitoring the time spent in each zone enables you to tailor your fitness regimen, optimize training routines, and maintain a balanced approach to physical exertion aligned with your fitness objectives.
