Walking is an excellent way to reduce your carbon footprint and stay healthy. The Walking app - Pedometer eStep by 1zlabs is a free lifestyle app designed to help you track your daily steps and carbon emission savings. The app's mission is to empower everyone to live a sustainable lifestyle by walking more and driving less.

Eco-Step is a pedometer that automatically records the number of steps taken in real-time, even when your screen is locked and the app is closed. It then generates a daily report that displays your steps and carbon emission savings. The app uses the built-in sensor to count your steps, so it barely consumes battery power. All features are 100% free, and there is no GPS tracking when counting your steps.
