Although most countries are in quarantine amidst the COVID-19 pandemic, a lot of people still need to go out of their homes and buy groceries. Sometimes grocery stores can become overwhelmed with an influx of people and have to start lineups outside, creating higher infection risks for both customers and employees. We wanted to find a way to help people plan their grocery trips and minimize their waiting times.

Line Jumper allows users to find a grocery store's contact information and to leave their own input on their shopping experience. It was submitted for the Data Day Grind hackathon.


Line Jumper uses crowdsourced data to determine the average wait time for specific grocery stores. When users submit their inputs on how occupied a given store is, their data gets stored into a database. This data would then allow other users to view updated information about the store.

Line Jumper is a cross-platform application for both Android and iOS. It was created using the Flutter SDK and the Dart programming language. Figma was used to prototype the application.
