BodyState requires you to track your sleep using your Apple Watch or a device that syncs with the Health app. Sleep tracking on the Apple Watch involves enabling Sleep Focus mode. You have the option to manually activate this mode each night before bed and deactivate it each morning, or set up a sleep schedule that automatically handles this. We recommend manually controlling Sleep Focus mode, as sleep schedules can vary.

Getting Started with Sleep Tracking on iPhone:

1. Open the Health app.

2. Tap "Browse" at the bottom of the screen.

3. Select "Sleep."

4. Tap "Get Started" under "Set Up Sleep."

5. Follow the prompts to define your Sleep Goals, Bedtime, Wake-Up Times, and activate Sleep Focus.

Getting Started with Sleep Tracking on Apple Watch:

1. Launch the Sleep app.

2. Complete the onscreen setup to create a sleep schedule.

To Activate Sleep Focus at Night:

1. Press the side button to open Control Center.

2. Tap the moon icon.

3. Choose "Sleep" from the menu; a small greenish-blue bed icon will then appear at the top of the watch face.

To Deactivate Sleep Focus in the Morning:

1. Access the Control Center again

2. Tap the moon icon.

3. Select "Sleep" and tap it to turn off Sleep Focus.

Important Considerations

• Sleep Tracking: Needs at least four hours of sleep data each night to be effective.

• Battery Charge: Ensure your device has at least a 30% charge before going to bed.

If you're tracking sleep but encountering an error that shows no sleep data, here are steps to troubleshoot the issue.

Initial Check:

• For BodyState to function properly, a detailed sleep report must be available in the Health app. To verify this, open the Health app on your iPhone, navigate to the Sleep section, and check for a report covering the current night, including stages like core and deep sleep. It is not sufficient to see "In bed" values. If you don't see a detailed sleep report, despite tracking your sleep, consider the following steps:

Speed Up Syncing:

• To speed up syncing, try opening the source device or app. For example, open the Sleep app on your Apple Watch, or if you use AutoSleep, open the app to kick-start the syncing process. If you use a Garmin device, open connect and make sure sleep data is synced.

General troubleshooting:

• Reload All Data: You can try to reload all data to see if the sleep data appears. To do this, navigate to Settings > Reload all data > tap Reload.

• Change Sleep Source: You can manually try to change the sleep source if you have other devices or apps that write to the Health App. To do this, in BodyState navigate to Settings > Data & Sources > Source Priority. After selecting a new source, the app will need to reload all data to incorporate this source for computing baselines and today's values. It is essential that this source has been used enough to provide sufficient data (at least 7 nights of sleep data) for accurate baselines.

Apple Watch Troubleshooting:

• Bluetooth Connectivity: Ensure Bluetooth is enabled on your device. It's easy to accidentally turn it off.

• Airplane Mode: Check if either your iPhone or Apple Watch is in airplane mode, which could prevent data synchronization.

• Passcode: When your watch is locked with a passcode, sleep data will be recorded but will not appear until the watch is unlocked. Many users charge their watch before bed and put it on just before sleeping, which prompts the need to enter the passcode.

• Sleep Tracking Setting: Check if 'Track Sleep with Apple Watch' is activated. This setting is vital for using Sleep Stages. To enable it, go to the Apple Watch App on your iPhone, scroll down to 'Sleep,' and toggle the 'Track Sleep with Apple Watch' option.

• Sleep Schedules and Focus: If you are using Apple's sleep schedules, make sure the 'Use Schedule for Sleep Focus' option is correctly configured. Incorrect settings here can lead to Sleep Focus turning off at inappropriate times, affecting data capture.

• Battery Levels: Verify if your Apple Watch battery dropped to 10% or lower. The watch needs sufficient power to record background heart rate data essential for sleep tracking.

• Wrist Detection: Confirm that wrist detection is enabled on your Apple Watch. This feature is necessary for gathering background heart rate data. Enable it in the Apple Watch app under the 'Passcode' settings by turning on 'Wrist Detection.'

You have the option to manually choose which sleep source BodyState should prioritize, such as a third-party app like Autosleep or a Garmin watch.

To do this, navigate to Settings > Data & Sources > Source Priority.

In the BodyState app, access the settings by tapping the cog icon in the top right corner. Next, tap on Data & Sources, then select Source Priority, and choose your preferred source.

After selecting a new source, the app will need to reload all data to incorporate this source for computing baselines and today's values. It is essential that this source has been used enough to provide sufficient data (at least 7 nights of sleep data) for accurate baselines.

Bodystate is compatible with any device that can transfer its data to Apple Health. However, not every device may integrate smoothly with Apple Health.

By default, BodyState gives priority to data from the Apple Watch. However, you have the option to manually choose which sleep source BodyState should prioritize, such as a third-party app like Autosleep or a Garmin watch.

To do this, in BodyState navigate to Settings > Data & Sources > Source Priority.

Currently, naps are not supported and won't directly improve your BodyState score, but naps can still help reduce fatigue and improve subsequent night's HRV and resting heart rate. It is not supported because there's no native nap tracking in watchOS. This feature will be introduced with the next watchOS 11 update.
