Ripple

Inspiration

A lot of people care about the environment and try to help by recycling, biking, or saving water. But many of them slowly give up, because they feel like theirs actions are useless. I saw this happen to many people around me. It's not like they just didn't care anymore, but they felt like their actions didn't make a difference. I wanted to fix that feeling, so I created a plan for an app that shows people their actions actually do add up when combined with everyone else's.

What it does

Ripple lets a whole community track their climate actions together. When you open the app, the first thing you see is the community's combined impact, such as how much carbon dioxide everyone has saved this month. You log small actions like biking or refilling a water bottle, then prove it by taking a live photo in the app, and your action gets added to the group total. Groups compete against each other, like dorm versus dorm, and when the community reaches a goal, a sponsor funds a real world reward.

How I built it

Since Ripple is currently an idea, most of our work went into research and design rather than coding. I started by researching the problem to make sure it was real, using studies like the Lancet survey on climate anxiety. I then planned out how the app would be built. It would run on both iPhone and Android using React Native, and use a service like Firebase or Supabase to handle logins, store data, and update the live community counter in real time. I designed an way that converts each action into carbon dioxide, water, or waste saved, using published conversion numbers from the EPA. Finally, I created mockups of the home screen to show how the app would look, and mapped out the full business plan behind it, including who it's for, how it makes money, and how it would grow.

Challenges I ran into

Our biggest challenge was verification, making sure people actually did the actions they logged, so the numbers stay accurate. I solved this by requiring photos to be taken live inside the app, so old or fake pictures can't be used. Another challenge was keeping the app simple. I had a lot of ideas, and I had to decide which features were core to the main goal and which ones to leave out. I also had to figure out a business model that could actually make money while keeping the app free for students.

Accomplishments that I'm proud of

I'm proud that I took a problem that sounds impossible to solve, people feeling like their actions don't matter, and turned it into a clear, focused product. I designed a full business plan covering who it's for, how it makes money, and how it grows. I also built clean mockups that show the idea at a glance. Most of all, I'm proud that our solution is based on real research and targets the actual cause of the problem, not just the surface.

What I learned

I learned that the hardest part of solving a problem is understanding it deeply, not just building something. I spent time figuring out why people really give up, which led me to the idea of showing collective impact instead of individual impact. I also learned how a business model works, things like customer segments, revenue streams, and cost structure, and how to explain our idea in a simple, clear way. Finally, I learned that focusing on one specific community first is more realistic than trying to reach everyone at once.

What's next for Ripple

Next, I want to build a working version of the app and test it with a single school club. From there, I would run a full competition on one campus with a local sponsor to see how well it keeps people engaged. If it works, I would sign up more schools, add automatic ways to verify actions, and give schools reports they can use officially. Over time, Ripple could expand beyond schools to companies and cities, and beyond climate to other kinds of community good, like volunteering and donation drives.
