You have two possibilities to update your steps and other records with StepsApp:

1. Keeping StepsApp in sync with Apple Health and your Apple Watch (this is particularly useful for users with an Apple Watch or a Third Party Watch)
2. Importing your data, updating your steps with the motion sensor of your phone and deactivating the sync mode.

In both cases the steps are being counted live.

How to change the sync mode:

• Open StepsApp
• Go to “Settings”
• Tap on “Apple Health” 
• Turn “Activities Sync” Off or On if you have a watch or other additional devices (such as a Garmin watch).
