Carbon Tire

Inspiration

I'm sure that we have all heard the phrase a Carbon Footprint but I realized that I didn't really know how much carbon I was emitting my self. Did it really matter if I biked to school and didn't have my parents drive me?

What it does

Carbon Tire is an app that measures how far you travel and whether you were biking or driving. Based on how far you were driving it calculates how much carbon you emitted (if you were driving) and saved (if you were biking). The calculations are based on studies from the EPA (United States Environmental Protection Agency). From the amount of carbon you save and emit it creates a score for you ranging from 0-100 with lower numbers being better. The average person has a score of 75 by the end of the month and the users goal is to have a score much lower than that. You can lower your score by biking more places.

How I built it

I built it using Kotlin and Android Studio. For getting the location I had to use the FusedLocationProviderClient library.

Challenges I ran into

It was my first time actually using a phone's location in an application and I learned a lot through the process. I had to make my mom drive me around a lot to test the app. It was also my first time making a circular progress bar.

Accomplishments that I'm proud of

I am very proud of how the app turned out. I am also proud of being able to learn how to use the phone's location as it can come handy in other applications I will make as well.

What I learned

I learned how to make a circular progress bar and use a device's location and do distance calculations. But the biggest thing I learned was how much carbon dioxide one drive to work can actually produce.

What's next for Carbon Tire

There are two things that I would like to add to my App. Firstly, I will add the feature to automatically detect the mode of transportation (bike vs car). Secondly, I will integrate my app with social media accounts so users can share their environmental impact achievements with friends and influence others to have even more impact.
