The Amazfit Pace is not compatible with the Amazfit - Activity + Sleep Tracker app. Therefore, you cannot view your activity using this app.
The Amazfit Pace is compatible with the Amazfit Watch app only and data collected on the device can only be viewed through the watch screen itself. It cannot be viewed through the mobile app.
Our developer team is working on integrating the two mobile applications for users to view their Amazfit Pace data not only through the watch screen but also on their mobile device. We hope to make this available in the near future. Thank you in advance for your patience.
