Earlier quoted context omitted.
> "You can also connect your favorite fitness devices and apps like Strava, Withings, Runtastic, Runkeeper and Noom Coach to Google Fit and we’ll surface all of the relevant data in one spot, giving you a clear and complete view of your fitness. No need to check one app to see your weight and another to review a run – with Google Fit, that data will all be surfaced in one, simple place."
Yes, I clearly read that line as I pulled a quote directly from it. If you read the quote they don't expand beyond what is already available in the app. If I track a 2 mile 20 minute run with another app, Google Fit (so far) only exposes the data as "Ran 20 minutes" completely eliminating the useful information. And if they have a hidden feature that does track distance as well, why isn't that exposed to me to manual…
