I'm just figuring out Steemit and the Actifit tracker. I have been using Google fit to track my activity for about a year when I bought an Android smartwatch for a considerable discount.
As far as I can tell, Google Fit doesn't seem to interface with Actifit which stinks. I also lost a very active day yesterday on the Actifit tracker because I failed to make sure it was running. That last one is completely on me.
I also admit that I have zero knowledge of what it takes to interface 2 applications, what Google may require to do it, or what Actifit doesn't want to compromise.
So with that said, I am still quite pleased to have an app where I just need to turn on and post my activity. Pretty simple.
