Facer Android App is not Working

Facer app for my android one plus 6 mobile is not working fine for me. It’s not tracking my daily activities like workout, running and walking activities. is there any error with the new versions. By the way, I have downloaded the latest version from here: Facer Watch Faces APK : Download v5.1.2_100533 for Android at AndroidCrew
Can I know whats the solution for my error?
