Your current streak is under your profile under personal records. I can see it in the app. So I guess the added it to the app since you asked 7 years ago.
Is there a way of tracking an activity streak without setting a specific goal? I'd like to be able to see how many days in a row I've run. That HAS to be an easy metric to add to the website or the app. I see that there is a widget that does this, but it's not compatible with my particular Garmin device.
Got here searching for the same. Yes, please add this nice people @garmin!
