HopIn

Transport is one of the largest sources of greenhouse gas emissions. HopIn was built for a two-week coding competition on the environment and climate, around one idea: help people who travel the same way share a car. Fewer cars means less CO2, less traffic and lower costs for everyone in it.

A mobile app in React Native and Expo with a Node.js backend.

• Drivers add a ride: where from, where to, the earliest departure and the latest arrival, how many seats are free, and on which days: one day, this week, or for several weeks.
• Passengers find rides going their way and join them. New matches arrive as notifications in real time ("We found a passenger for your ride").
• Every ride has its own page with the start, the destination, the times, who is driving and who is in the car, and a preview of the route on the map. Problems can be reported from there.
• Driver and passengers message each other in the app to agree on the pickup.
• The profile shows the impact: rides shared as a passenger, passengers picked up as a driver, and how many cars that took off the road.

There is no public code for this project. The screenshots use demo data: the names, rides and conversations are made up. The app's demo is in Polish.
