How do I check my sleep patterns on the Kore 2.0?

Kore 2.0 smartwatch must be worn overnight at least once in order to monitor your sleep patterns in the KoreHealth app.

Sleep as you normally would with your Kore 2.0 fitness watch on the outside of your arm, just below the wrist ensuring skin and sensors are touching for the best reading.

When you navigate to the Sleep function on the KoreHealth app, you’ll see your sleep cycle broken down into 4 categories: Awake, REM, Light, and Deep. There is also a breakdown of the average time you spend in deep sleep, light sleep, and awake. With the KoreHealth app you are able to review the data collected on your Kore 2.0 watch and break down your sleep patterns hourly, daily, weekly and monthly!

If your smartphone is not in range of Kore 2.0 while you sleep, all of your sleep data from the night before will sync automatically once Kore 2.0 pairs with the KoreHealth app.

The watch will monitor sleep data in the full 24hrs interval. The watch will ONLY display the longest sleeping duration in this 24hrs period. In addition, the watch will ONLY record different sleep if there is 2 hrs in between the sleeps.

Also keep in mind, the sleep data is determined by the movement of the wrist during sleep. Be sure that the front of the device is facing up when you wear it, adjust the watch and ensure that it fits the skin to avoid wearing too loose or too tight. If you don’t plan on wearing it while you sleep, take it off and put it sideways or facedown on the table to reduce miscalculation of sleep.

If you believe the sleep data to be inaccurate it may be as a result of the below:

1. The sensor might misjudge that you are awake if there are rapid movements or you fall asleep on transportation. Example of this would be taking a nap on a bus or train, although the biometric input of a sleeping pattern can be detected, the vibration of public transport can register the user as “active”, thus the nap/sleep is not recorded.
2. If you sleep less than 30 mins
3. If you are wearing the watch too loose, it might cause abnormal sleep records. 
4. The watch is in a relatively stable state, and there is a motion range similar to that of sleep, which makes the device misjudge it as sleep. For example, the watch might detect sleep while watching TV, reading books, or sitting on a stool right after you wake up because your movement amplitude and frequency are relatively small. 
5. After you are awake, if there is minimal movement or do not perform screen operations, the device will not exit sleep mode immediately, which may result in the device still recording you as asleep.
6. Waking time increases by mistake: If you turn over unconsciously during sleep, you may be judged to be awake, and the number of wakefulness will increase. Other causes of movement such as sleep walking, large movement while turning in bed, etc.
7. Waking time decreases by mistake: If the amount of activity is relatively small after being awake, and you are still lying in bed, the device may not detect it. 

If you are NOT wearing the watch but you notice inaccuracies in the sleep tracking function it may be a result of the below:

1. The optical sensor group senses changes in light, not a bioelectric signal. The sensor itself cannot sense a living body. When the watch is placed on a table, sink, sofa, quilt, the light sensor might sense the watch is on the wrist. It will then judge that it is currently in the wearing state, and sleep monitoring is carried out, resulting in sleep data.
2. When the bottom of the wearable device is obstructed or slightly shaken, it may cause the device to enter sleep monitoring and incorrectly record sleep.
