This article will help you if you encounter any of the following issues:

- You have no sleep data in the Withings App app
- Part of your night is missing from your sleep data
- Your data seems inaccurate

You have no sleep data in the Withings App

If you have no sleep data in the Withings App app:

1. Make sure that your Withings Move appears in Devices in the Withings App app.
   If not, you need to install it.
2. Select Devices in the Withings App and make sure that your Withings Move is connected. If not, try to turn off Bluetooth on your mobile device and then turn it back on.
   
   You'll know that the connection with your Withings Move has been established when you can access the Alarm or Notifications screens. Your data should then start syncing.

If you still encounter issues, reach out to Customer Service by clicking the Contact Us button at the bottom of the page.

Parts of your night is missing from your sleep data

If some parts of your night are missing from your sleep data, it may be because you move a lot in your sleep. Withings Move can be quite sensitive to motion until it is certain that you're asleep. This can affect the beginning and the end of your sleep data.

Note that at least 3 hours of sleep are necessary to receive sleep data in the Withings App. We have chosen to disable the detection of naps to focus on an improved tracking of your nights.

Your data seems inaccurate

If your data seems inaccurate, it may be that:

• You're also using a Withings Aura to track your sleep. If you use both devices, sleep data coming from the Withings Aura will systematically overwrite any sleep data coming from your Withings Move.
• You're wearing your Withings Move in your pocket, in which case sleep can be falsely detected whenever you stop moving. We strongly suggest that you wear your Withings Move on your wrist.
• You have an unusual sleep pattern due to health or work-related situations. 

Notes:

• A prolonged lying down position can trigger sleep detection. For example, if you are in bed doing something such as reading or watching TV for about 3 hours, sleep can be detected from lack of movement.
• The watch will need to take at least 150 steps in for sleep mode to transition to activity in the morning.
