But they are. Keep, Fit are prime examples of stretching but offering a mediocre "service".

The way I see it, Google turned hard into a direction from building services with APIs into data collection silos. Google+ with Photos, Keep, Fit, Now. The data is even isolated from each other or really hard to access : - you can't access Keep data anywhere, or what you upload on it - Google+ Photos are available on web, not in Drive. You can see Drive photos in it, but you can't edit them with auto awesome

Fit is so basic that it offers practically nothing that it doesn't already exists out there. Data representation is in a form of one graph of total calories/steps. It does require you to enable location tracking though, to be able to automatically track steps/workouts (how suprising), which takes a major effect on the battery life.

Google is coming for your data and coming hard.
