Requirements for Sleep Data Display on Your NOWATCH App

If your NOWATCH app isn't displaying sleep data, consider these possible explanations and solutions:

  1. Proper Placement

    • Make sure the crown points at 8 o'clock.

    • Ensure your NOWATCH fits snugly and comfortably on your wrist.

  2. Data Storage and Erasure.

    NOWATCH continues to collect data even when disconnected from the app. The data is transferred once the connection is restored.

    Data stored on the device is irretrievably erased upon:

    • Reboot

    • Factory reset

    • When the battery drains

  3. Software Updates

    • Ensure you're using the latest software, as updates may include fixes for sleep-tracking issues.

    • While not compulsory, data transfer and the app work better when the app is open or running in the background.

  4. Data Processing Time

    • Sleep data processing may take a few hours. It may be recalculated several times throughout the day.

Sleep Data Processing

You wake up and reach for your phone to see how you have slept. Your sleep data, however, may not be ready for display.

Due to the data processing involved in sleep scoring, which starts only after waking up, it may take some time for your sleep data to show. Additionally, it may be recalculated several times throughout the day.

Sleep Detection and Scoring

The algorithm tracks your movement and heart rate to determine whether you are asleep or awake. A decrease in movement and heart rate indicates sleep, while an increase signifies wakefulness. This helps determine sleep duration.

After detecting wakefulness, the algorithm calculates the sleep stage for every 30 seconds you were asleep. Once each sleep stage is scored, the data is sent to the app.

As a result, it may take some time before your sleep data is ready for display.
