Nice design... not sure what this is doing that the Fitbit software doesn't though. Or Strava for that matter.
How long did that take you though? At least 90 minutes I would guess? 12 miles is 19 kilometers, that's almost a half-marathon. Not exactly typical but good for you.
Don't think 5km is enough frankly. I mean it's good but i can't actually hit my 3k calories-burned goal in a day, if I only ran 5km as part of my 10k steps. I'd be under until I was closer to 14-15k steps.
Well, for starters, it's a free app and you don't need anything else but a smartphone for it..
There are probably lots of other wearables and/or apps that do a whole lot more then Human, but I enjoy the easy interface and the simple fact it just works in the background.
