Tracking your sleep is a great way to understand your rest patterns and build more consistent habits. If you use Apple Health to record sleep, you can sync that data directly to Second Nature.
Step 1: Give Second Nature permission to read your sleep data
Open the Health app on your iPhone.
Tap your profile picture in the top-right corner.
Scroll down to Privacy, then tap Apps.
Tap Second Nature and make sure Sleep Analysis is toggled on.
Step 2: Sync your sleep data to Second Nature
Once permissions are enabled, open the Second Nature app and tap Sync at the top of your Track page. Your sleep data will pull through automatically.
How to manually add sleep data in Apple Health
If your sleep wasn't recorded automatically (for example, if you don't use a wearable), you can add it manually:
Open the Health app.
Tap Browse in the bottom-right corner.
Select Sleep under Health Categories.
Tap Sleep Analysis, then Add Data in the top-right corner.
Enter your sleep and wake times, then tap Add.
