Human is an iPhone app created to track all your daily exercise and calories.
The app itself is wonderful, and cities.human.co takes it to another level.
You can see real-time stats for 900 cities worldwide, and see how the rest of the world is moving too. The daily rankings for the top ten cities in walking, biking, running and other activities are posted to the site daily.
Is your locale in the top 10? Get out there and #repyourcity!
