I installed it because, because I hoped that I could say while standing on the scale, "Hey Google, record my weight as X". This feature did not exist, so it was immediately off to a bad start. It got worse when I linked it to my calorie counter app (Lose It!), and Fit started writing random weights to the counter app daily. I had to disable and ultimately stop using Fit because of this. Fit also has an incomprehensible "Heart Point" system, and a strange way of counting calories burned each day. Fit also has a confusingly-named section for "body measurements", but it doesn't seem to actually have a space to put body measures (such as waist size, bicep size, etc). Instead, this was more of a vital statics section (blood pressure, respiration, etc.). Overall, Google Fit seems to have a lot of features, but all the features scream for you attention with endless notifications (until you disable them and get no notifications or reminders). Some of these features may be useful, the I wanted the app to be a central place to link my various fitness app, and Google Fit simply does a poor job a linking and syncing info to/from other fitness apps. The Fit app is just to confusing and clunky to be of much use.
