How Google Fit has made me a slave to my phone

About a month ago, I discovered something called Google Fit. The programme, or 'app' as everyone calls them these days, had been on my phone since I received it as a gift the Christmas. But for 16 months it lay dormant in the inner bowels of my phone, along with YT Music, Calendar and Assistant, whatever they are. As far as I am concerned, a phone is predominantly for making and receiving phone calls, sending text messages, or maybe emails if I'm feeling adventurous.
