A popular European app that incentivizes users to walk instead of drive with cash rewards is coming to the U.S. — and the developers behind it are betting that it can get people moving on their legs even on dangerous American roads.

For the first time, stateside cell phone users can now download the popular WeWard app, which translates the number of steps they take each day into digital coins redeemable for real-world prizes such as discounts to major retailers, donation credits to charities, and even real cash.

Its creator is optimistic that the app has the potential to get Americans walking — or at least, to get them talking about why walking matters.
