Since you mentioned Garmin Connect in this thread, I would like to throw in my five cents too. I’m in the Garmin ecosystem for my fitness tracking devices, so it would be amazing if the game could get my step counts from Garmin Connect, since that’s where I’m collecting them anyway, and lugging my phone around to do the step counting can be a bit cumbersome. But if the game is fun enough, I guess it’s not a dealbreaker for the time being!
