Missing heart rate, or distance, or cadence in the application ? Your Activities are recorded without any GPS route ?
You may have inadvertently dismissed the 'authorizations' screens at first app install. It's necessary to not only click 'Yes' but pay attention to toggle all switches 'ON'.
2 options to fix this:
Uninstall the mobile (and watch) application. Then, during the whole reinstall process, watch carefully for the prompt and ensure you toggle all switches ON.
Enable health and location data access (access to heart rate data, localisation, distance, speed etc.) :
1) On your iPhone, open "Settings" > "Privacy"
2) Choose "Health", search for ActiveLook and ensure *all* toggles are ON. Then tap "back".
3) Choose "Bluetooth", search for ActiveLook app and ensure toggle is ON. Then tap "back".
4) Choose "Location Services", search for ActiveLook app and ensure "While Using the App" is enabled. Then tap "back".
5) Choose "Motion & Fitness", search for ActiveLook app and ensure toggle is ON. Then tap "back".
