Shift by Green Streets

Green Streets Initiative

About this app

Shift tracks your daily trips and shows the real impact of choosing to walk, bike, or take transit. Built by Green Streets Initiative, a Boston-area nonprofit, Shift makes sustainable transportation fun, measurable, and rewarding.

HOW IT WORKS
Shift automatically detects your trips using background location — no manual logging needed. Your Shift Rate shows the percentage of trips you take by active or shared modes. Watch it climb as you build better habits.

LEVEL UP
Every active trip earns XP. Build streaks, climb through five tiers from Starter to Trailblazer, and unlock multipliers up to 5x. Hit milestones to unlock achievement badges and qualify for perks from local Rewards Partners.

COMPETE WITH YOUR COMMUNITY
Join your neighborhood, workplace, or school group. See how you stack up on leaderboards and track your community's collective impact.

SEE YOUR IMPACT
Track the money you save, CO₂ emissions you avoid, and calories you burn — all calculated from your real trips.
