Frequent flyer programs are a frustrating paradox. As humans, we’re always on the hunt for a discount, but how often do most of us fly? Once every few months? Once a year? For the most part, we spend far more time traveling in a car or bus, on a bike, or on foot. To the right kind of mind, that sounds like an opportunity, which is why a new Silicon Valley startup called Miles has built a rewards program for all these other modes of transportation. The cost? You have to let Miles follow you everywhere.

Today, the company launched a free iOS app of the same name (Android version coming soon) that lets people rack up miles based on all the different modes of ground transportation they use to move around each day. Ostensibly, the greener the transportation method, the bigger a multiplier assigned to those miles: one mile traveled in a car nets you one reward mile, for example, while one mile in a ride-share is worth two, a mile of biking is worth five, and one mile of walking or running is worth 10. (One mile of flying is worth just 0.1 miles.)
