Fitness × Environment: track your activity and your CO₂

CarbonTracker is an open-source, privacy-first fitness app that helps you see the environmental impact of walking, running, and cycling. Track your routes on a map, estimate the carbon emissions you may save compared with car and bus travel, and monitor your fitness activity. Your data stays on your device, with no account required. It also includes a Wear OS companion for tracking activity from your wrist.
I started building CarbonTracker because I kept thinking about two things: how much personal data fitness apps collect, and how little we get to see the environmental impact of our everyday choices.
I wanted to bring these two ideas together in one place. What if you could track your fitness, record a walk or bike ride, and see how much carbon you could potentially save compared to travelling by car or bus, without needing to create an account or upload your personal data to a server?
That idea became CarbonTracker 🌱
I wanted to build something that connects personal well-being with environmental awareness while keeping privacy at the heart of the experience. It’s also open source, developed under AOSSIE, and has a Wear OS companion.
This project has been a learning experience for me, and there’s still so much to improve. I’m sharing it here because I’d genuinely love to hear what you think, what could be better, and what you’d like to see next.
Maybe making a difference doesn't always start with something big. Sometimes, it starts with one small step. 🌍
